Rusty Nail from the Beer post..
I sometimes like to take a section of a photograph and cropped a portion of it out.
When I set my camera to the highest quality settings the photos average being 1.8MB or 3008 x 2000 pixels in size. Which are huge to say the least.
Once a section is cropped. I sometimes am amazed at the detail. Such is the case with the Nail head from the old board taken while shooting shots of the old Steele/Tin beer cans. Which are the results of such cropping's in the above photo.
