Antiquesilver...I imagine that ISO is not changeable when in any semi automatic mode. The camera wants to do that for you so it will most likely be automatic. However you should be able to raise the EV just one notch up to +0.3, or get a stronger light bulb. Also try substituting the thin cloth with white tissue paper or tracing paper. The cloth might be cutting out too much light. I know what you mean about too strong a light blowing out the detail on the silver pieces. But keep experimenting to get the right combination of camera setting, light and diffusor. If you are interested in reading photography books, I can highly recommend this one "Light - Science & Magic. An Introduction to Photographic Lighting."" by Fil Hunter, Steven Biver, Paul Fuqua. There are detailed explanations of setting up tabletop lighting with a whole chapter dealing with how to photograph metal objects. You might want to have a look in your library or bookstores. The ISBN (I have the 3rd edition) is: ISBN-13:978-0-240-80819-2 , published by Focal Press. Tutorial number nine will be a few days late this week. Probably have it ready for the weekend since we had a lot to do this week, including rescuing our new cat from a neighbour's locked backyard LOL. (All turned out well there.) SharonCb

Great pictures, kt! This my first time photographing fireworks...Oh my gosh, it was SO much fun! I learned some lessons. I was almost too close for my lens length and got a lot of "partials". I changed my shutter opening time back and forth depending on how fast they were launching them. I'm looking forward to next year! I'll post a few more when I get them converted.

This forum article is by member bob_71. One of the finest pieces of marketing, ever, has been the coining of the phrase "Point-and-Shoot" camera. In three simple words it promises the ease of operation of an old Kodak Brownie and that you will be able to produce National Geographic quality photographs. Few of us ever produce pictures of such high quality...but we could! The new digital cameras have capabilities beyond our imagination! Unfortunately, the operator's manuals are written by the brilliant young engineers who have grown up with the technology and the language that surrounds it. They fail to understand that many buyers of cameras received their education somewhere around the middle of the last century...many (most?) of the terms in the manual did not even exist at that time. The language discourages these readers so the manual gets lightly scanned, or ignored. When this happens, the camera is used poorly and often with the wrong settings. This mini-tutorial is my attempt at simplifying the language while suggesting the "tweaks" that I use to customize my camera. My goal is to be able to walk outside, observe the weather conditions, make one setting adjustment to compensate for the existing weather and then to "point-and-shoot" all day with reasonable expectations of high quality photos. The camera manufacturer has to produce a camera that is set up to take average pictures in almost any area, but it is NOT set up to take OUTSTANDING pictures of anything. Whether the customer will be using it for architecture, landscapes, sports, portraits, or for butterflies, many settings will have to be adjusted for that purpose. When all the settings are correctly tweaked, the digital camera becomes capable of coping with the special requirements in a simple and straight-forward manner. There are two settings that are paramount in achieving quality, regardless of the subject matter. The first of these, and the most critical, is usually referred to as the IMAGE RECORDING QUALITY. In my opinion, it is a setting of the past that has outlived its time. When digital cameras first came out, storage capacity (same as number of shots on a roll of film) was quite low. For example, the memory space within your camera might allow only 25 high-quality pictures before running out. To boost that, they added software that would allow you to increase up to a hundred the number of shots that your camera could store. The trade-off was that in order to do so, they had to reduce the size of the file for each picture that, in turn, reduced the quality drastically. You ended up with 100 lousy pictures. The high quality that your camera (and you) had shot is gone forever...you can not get it back! Whether you shoot landscapes or butterflies...this one is a no-brainer: Select the option for the HIGHEST QUALITY SETTING available. Set it now and never, ever change it, regardless of what you are shooting. The second setting actually occurs within your editing software. It is a setting that is also designed to allow for smaller picture files (read: Lousy quality pictures) to reduce memory space usage on your hard drive. This option is based on the same as above...smaller files require less storage space...smaller files equate to reduced quality. Most of us utilize some form of post-camera software to edit our photos before we SAVE them. After you have completed the editing and wish to close and save this file to a folder, it will query you to select the quality level at which you would like it SAVED. No-brainer time again: Save at highest quality offered. I have all my photos, at the highest level of quality, stored on the same hard drive that I have used for the last four years and that houses everything from my computer. According to my pie-chart of available space, I still have room for over 40,000 photos! Summarizing these two critical options, (1) choose the highest quality for IMAGE RECORDING QUALITY and (2) choose the highest quality when SAVING from your editing software. If you select less than that, you can never get it back! The montage below shows the quality difference that occurs as a result of the above two options. These two photos were shot with a camera on a tripod and with all but two settings identical. The photo on the left was shot with IMAGE RECORDING QUALITY at it's lowest quality option and it was SAVED in editing to its lowest quality option. The photo on the right was shot with both options at the highest level. (Scroll down to see the montage mentioned above) Now for the settings that will customize your camera for shooting butterflies. We need to determine the characteristics of butterfly photography that are problematic. They are tiny creatures that rarely fill the frame of the camera...they are defensive in nature which causes them to "spook" as we approach...they CAN fly...and they are cold-blooded, meaning that most photos will be taken in full sunlight rather than in easier to handle lighting situations. In my opinion, the qualities that cause a photo to be less than good are poor focus (includes motion blur) and poor exposure. FOCUS: Most cameras have an option for operating in the AUTO FOCUS mode or the MANUAL FOCUS mode. I strongly urge you to opt for the AUTO FOCUS. It is faster, refocuses for each shot and, try as I might, I can not better its accuracy or consistency. When you select AUTO FOCUS, there are usually about three options from which to select. The first is a setting based on shooting still subjects. The second option is for shooting moving subjects and the third is a combination of the two. I get my best results when the "STILL SUBJECTS" option is selected. The butterflies are usually perched when photographed. With my Canon camera, this option is called ONE SHOT AF. I set it here right after I bought it when I did the initial camera settings and have left it there. EXPOSURE: The amount of light that reaches the sensor of your camera is based on the size of the opening that lets in the light (the aperture) and the amount of time that the light is allowed to come in (the shutter speed). When operating in FULL MANUAL, the operator must select and set both the aperture and the shutter speed. This requires lots of experience and/or a metering device if it is to be accurate. This is NOT my preferred operational mode! On some rare occasions, manual is the best but only rarely! FULL AUTO is not my preferred mode, either. There are two other modes that offer equally accurate exposure but allow for better control of other factors such as stopping movement and depth-of-field. These are called APERTURE PRIORITY and SHUTTER PRIORITY. They are based on the operator selecting either one of these controls and allowing the camera's software to select the other. Without getting into the technical aspects (they are tutorials of their own), the aperture size controls the depth-of-field (the portion of the photo that is in sharp focus) while the speed of the shutter can "stop" the blurring effects of motion. Thusly, for me, when I go outside to shoot, if the breezes are blowing I select SHUTTER PRIORITY, set the shutter speed at 1/400 second (which is usually enough to eliminate the movement of the flowers that the butterflies are on) and make no further changes unless the wind goes away. If the wind is not a concern, I select APERTURE PRIORITY and select an f-stop of f/5.6 or higher so I get an acceptable depth-of-field. One of the toughest things to overcome in butterfly photography is the required meter readings for proper exposure. The difficulty arises due to the camera's desire to measure the full frame area while the area occupied by the butterfly is only a small fraction of that area. The skittishness of butterflies has taught us to shoot our first pictures when we get to about six feet away. We can ease in further and sometimes we will be allowed to get quite close but we are usually faced with a small bug in a big garden. This requires that we "tweak" the metering settings to conform with reality. With most cameras the metering settings consist of three or more options serving as choices that control the parts of the image area that will be considered when setting exposures. The first option (variously named EVALUATIVE, MULTI-PATTERN, MULTI, etc.) is usually from nine to more than forty somewhat evenly-spaced points that are "read" and averaged to arrive at the exposure. This is essentially useless for any small subjects. The second option is called "CENTER WEIGHTED" and uses a circle around the center that comprises about 30% of the image area for the metering...better than the first option but still not the best. The final option is the best choice for butterflies...it is called SPOT. It is based on about 3%-4% of the area in a circle right around the middle of which our butterfly is a prominent part. This is how I keep my camera at all times regardless of what I am shooting. It is my belief that this setting is used to influence the auto focus function even though the operating manual does not specifically state this. One of the main settings for me is one called EXPOSURE VALUE or EV. The person(s) who wrote the software for your camera had to, at some point, make a decision as to what constituted the "correct" exposure. It will approximate the middle-of-the-road point that is not too dark and not too bright. It can vary slightly from camera maker to camera maker since it is a judgmental call. They have all set up an EV adjustment (usually as a slider) that is graduated in 1/3 f-stop increments from -2 full stops to +2 full stops. The camera comes out of the box set to shoot with the exposures that yield a photo that would come with shooting at zero adjustment. When you adjust to the left or right of zero, you are altering the aim point to either an overall darker image or an overall lighter image. Your camera will still do its superior job of metering and setting exposures...it's just that you have told it "I like what you are doing but I would like it a little better if your results were just a tad darker". My personal results fit my taste better with -2 increments (-2/3 f/stops). One of the reasons that I select a slightly darker image is that most of my shots are in full sun and the chance of overexposure is great with the vivid colors of the flowers that butterflies nectar on. The second reason is that editing software can correct for considerable underexposure but a picture that is overexposed is mainly lost forever. Burned out highlights are irretrievable. I occasionally shoot a photo that appears a little "off" when I review it on the camera monitor. When I do, I usually shoot two more photos of the same subject...one that has one f-stop increment more than the original and another with one f-stop increment less. This is called "bracketing" the exposure. When I edit them, I keep one and trash the other two. A small group of settings that I consider "personal taste modifiers" include contrast, saturation and brightness. I keep these all at +1...your taste may differ from mine. I do not alter the sharpness setting. I leave it at the manufacturers settings and make any adjustments in my editing software. ISO: These settings serve to modify the sensor's sensitivity to light. Increasing the ISO number allows your camera to arrive at the proper exposure in low-light situations. The trade-off is that you lose quality in proportion to the increase in the ISO number. The reduced quality manifests itself with softer focus, color faults and the introduction of tiny specks of color that increases progressively with the increase in ISO number. Most cameras yield pretty good results up to ISO400...above that can be less than good. I keep my camera at its lowest ISO setting of ISO 80. When you increase the ISO setting the camera must adjust the aperture or shutter speed. Shooting in full sunlight with high ISO settings can cause your camera to be unable to correct to a proper level of exposure. WHITE BALANCE: This refers to your camera's ability to correct from light sources that are less than pure white (the camera's own flash is considered pure white). Pure sunlight produces shades of yellow, red and other colors at different times of day and based on many other factors. Incandescent and fluorescent lights vary greatly from daylight sources. The internal software of most digital cameras when set on AUTO does a superb job of white balancing. A few years ago, the digital cameras had difficulty with vivid colors like dark red and purple but that is history. The recent cameras capture the toughest colors with ease. If spot-on color is called for, most digitals offer a CUSTOM setting that really works...it is cumbersome but will get the job done. In my experience, improper exposure is more often the cause of poor color, rather than off-white light sources or improper white balance settings. Recap of Settings: IMAGE RECORDING QUALITY: The highest level available. SAVE QUALITY: The highest level available FOCUS: AUTO with STILL OPTION OPERATING MODE: Aperture Priority if wind is not a problem, Shutter Priority if wind is a factor DO NOT SELECT MANUAL EXPOSURE VALUE: (-2) increments=(-2/3) f/stops METERING: Spot WHITE BALANCE: Auto ISO: Lowest number available CONTRAST: (+1) SATURATION: (+1) BRIGHTNESS: (+1) SHARPNESS: Make no change Motion blur appears as a blurry, or improperly focused photo. It is a function of movement that usually is generated by the photographer. The best solution that I have found is a good old-fashioned sturdy tripod. Many of today's cameras or lenses have image stabilization capabilities...if yours does, keep the switch ON! It can really help. I sincerely hope that your results give you as much pleasure as mine has given me. Bob Image by: bob_71Difference in Quality Settings

Posted by canarybird (My Page) on Wed, Aug 12, 09 at 11:45 Food Photo Tips: Part 6 - Making a Mini Light Box Hi again everyone. I'm back with another entry on how to use your digital camera for taking tabletop photos. This time I'm going to show how to make a miniature version of a light box, which can be useful for photographing small objects. I'm also working on making a full sized box out of a cardboard printer box which will be used for photographing larger objects, including plates and dishes of food. Mini box (left) Full size box under construction (right) But it might be easier to practise with a mini box to test your results and your skills with a box cutter or sharp scissors. If you have a handy teenager, (or other person clever with crafts and model building, who won't cut off a finger with the box cutter) you may enlist some help with this although it takes less than an hour to make, requires no special skills and doesn't have to be good looking. The idea of a light box is to create a partially enclosed 'white room', with white walls, a white sweep (that paper background we made previously in Part 4 - Seamless Backgrounds), with cutout windows and ceiling covered with white paper, into which we project a strong overhead light and usually a light on either side aimed at the white paper windows so that any object introduced into the box will be bathed in total white light with no shadows. You will have often seen pictures on the web of an object which seems to float on a pure white background. Eg: Cook's Thesaurus. This effect can be achieved in a light box. And it's quite entertaining to see what you can produce from this setup. These last two pictures were taken with my 15 watt CFL desk lamp overhead and one 7 watt CFL spot lamp (that green one) at the left window. Even better would be a 2nd spot pointing at the right window. (I need to go out and buy that 2nd spot lamp...they cost about $12 here so not an expensive item and good for the mini box.) Construction of the Mini Box: Materials needed: small box of sturdy cardboard, box cutter or small sharp scissors, ruler or metal straight edge, pen, glue stick, white paper (I always seem to use printer paper.) I used a small box measuring 5.25 x 7 inches (13.5 x 18 cm) that contained a little desk lamp. You can use a larger box as well of course, but your lights will have to be accordingly more powerful. And I think it's better that you keep it as a vertical box, higher than wider, so that the lid opening will be your ceiling. We can still make the bigger box later once we have caught the idea of how best to create the whitest environment. On my little box I took off the top flaps of the lid and using a box cutter, cut out windows on the sides, leaving a frame of cardboard about 1 inch (2.5 cm) all around, except for the bottom edge of the front 'door' which I cut off. Then I took white printer paper and after cutting it to the size of one side (5.25 x 7 inches/ 13.5 x 18 cm) glued it with a glue stick into the INSIDE of a window side, then repeated that on the inside of the window facing it. Glue carefully and smooth out any wrinkles, which would show up in your photos. To further cover the edges, cut out strips of white paper to size and overlap the newly installed white paper to the back wall and the floor, smoothing carefully so the edges are well stuck down and wrinkle free. Do this on both window sides. Cut a paper sweep to go inside your box, but DON"T GLUE it in, just slide it in so it is removable when it becomes spotted . The measurements should be....width a little smaller than the width of your box. In my example, with a 5.25 inch (13.5 cm) box width, my paper sweep was perfect at 1/4 inch less than the box width...that is at 5 inches wide (11.5 cm). Length of the sweep:....start with a piece of paper a little shorter than the box height plus the box depth (from back wall to front door) and slip it into place until it reaches the edges of the door, as in the photo below. Check that you have a nice curve in the sweep, that it reaches the 'front door' and trim off any excess that sticks up over the top at the back. The finished box should look something like this. Many light boxes also use a thin sheet of paper...often white tissue paper or white tracing paper over the 'roof' of the box and this will give you a soft diffused light. If you are going to photograph any reflective item of metal, ceramic or glass you won't want a reflection of the light bulb in the top lamp showing on your object, so you should then use a thin white material or paper to soften the white glare. If you have a good strong light on both top and sides you will be okay with the diffusor on top as the light will be sufficient. If the light is too strong, then move the lamps away a little from the box. Some examples with fruit: First a sideview of the setup and one example of creating a very soft photo using Exposure Compensation (EV +1.3)... that's 4 clicks up from 0.0... to give deliberate over exposure. Here I was able to get photos using just the overhead desk lamp. If you don't have extra lamps (they must all have the same type of bulb...tungsten or CFL, not mixed) see how you can do with the overhead lamp close to the top opening of your box and raising the EV value to make the picture lighter. This you can do while looking through the viewfinder before taking the photo. A little less raising of the Exposure Compensation, that is.... pushing it up 3 clicks (instead of 4) to EV +1.0, makes the image a little less over exposed and more defined (left photo). With no EV changes to the picture, you would have a normal exposure, as in the second photo. Now you know how to make misty white photos if you wish to have that effect. When you raise the EV value using the plus+, you are actually decreasing the shutter speed of your camera, so it stays open longer, lets in more light and gives you a more exposed (lighter) image. Conversely, when you lower the EV value using the minus -, you are in fact increasing the shutter speed, the shutter closes sooner, letting in less light and your image is darker. If you manage to make this mini light box, try using a PORTRAIT setting, and maybe add a click on the MACRO option as mentioned below. Remember to set the White Balance WB for the type of bulb you are using...hopefully you have a CFL fluorescent in there, and practice using the EV button to lighten or darken your image while looking through the viewfinder. I think this is enough for one day but I did want to introduce MACRO, or closeup photography. If you look at the back your camera you will have noticed a little tulip icon somewhere on or near the round touchpad. That is your option to tell the camera that you want to make closeup photos. You should be able to click on it from any of the other options that you have, such as AUTO, PORTRAIT, INDOOR. By clicking on the tulip icon you will probably bring up three options: OFF, the tulip icon representing MACRO, or another tulip icon with a small 's' beside it. Some point and shoot cameras may not have this second tulip but it refers to SUPER MACRO where you can get even closer to your subject. Try it out....remember you can still be in another mode and add the macro option. I'll explain more next time with examples of how you can capture very close, sharp pictures of food, insects and plants. I hope you are understanding it all and if you have questions please ask here or PM me. So thanks for joining me. I'll be uploading the next installment soon.

I gave it a quick trial run using an under counter light as an overhead with a thin cloth on top & a POS snake light on one side. I'm amazed that I got good shots without a tripod, although I know it will be necessary when I use a macro lense for the maker's mark photos. I didn't have time today for that, but wanted to thank you for taking time to enlighten all of us who aren't quite in the 21st century - at least photography-wise!

The focusing looks good but you do need a stronger light to brighten up the images. Keep the thin cloth on top as you have done to avoid sharp reflections on the silver (beautiful piece by the way,) and raise the Exposure Compensation (EV) higher...start with +0.3, then +0.7, and +1.0, taking one or two shots at each and see how they turn out. You would need a tripod as changing the Exposure Compensation will probably slow the shutter speed, opening up the possibility of camera shake. I would also check the ISO setting if you can do that. Perhaps that's not possible if you are using an automatic setting. Raising the ISO increases the camera sensor's sensitivity to light, so a higher number makes the photo brighter. (Same as when using film we could buy ASA 100, 200 or 400 for different film speeds.) For sure you can change the ISO when in manual or semi-automatic modes, which show as M, A, S, or P on your mode dial. I'm so glad to see you are trying this out and showing your photos here! Keep going....you are doing well!

Taking a decent photo of silver without glare, blur, & a tripod is no small feat so P&S is a small miracle! I did play with the EV but overexposure was a problem when going higher; maybe not so much overexposure as a loss of silver details - another problem w/silver. Yesterday, I realized the overhead light I used is halogen & I changed my setting to adjust for it & that got rid of the yellow tones. I can't remember if I can change the ISO in Portrait mode or not - I've found so many things on this camera that I didn't know were there, it's mindboggling! FYI - it's a Panasonic Lumix. o RE: Food Photo Tips: Part 6 - Mini Light Box & Macro clip this post email this post what is this? see most clipped and recent clippings * Posted by canarybird (My Page) on Wed, Sep 2, 09 at 18:01 Antiquesilver...I imagine that ISO is not changeable when in any semi automatic mode.
