Depth of Field
By: Mark SincevichIf you would like to be able to photograph jewelry or other smaller objects and want to make sure that the entire product is in focus, then make sure you have a macro lens. An example is a macro 1:2.5 (that is what is indicated on the lens).
First, it's a good idea to have a light tent and lights to photograph small objects like jewelry. If you are a Canon photographer, then having the Canon Macro f/2.5 is a great first step. The light tent is about the size of a medium-sized stereo speaker. Also, this lens gives you close-ups up to half of life size. Certainly the f/2.5 gives you a great background blur, but if maximize the aperture, you can go as high as f/32!
If you are shooting at a shutter speed 1/125 at f/2.5 with ISO 100, this might not give you enough light. First, put your camera on a tripod if you haven’t already done so. You will also need a cable release. I recommend that you try a shutter speed of 1/30 of a second. Change the aperture to something like f/8 or f/11. This should give you plenty of room for depth of field. Do a meter reading in your camera (better yet with a hand-held light meter) … you might have to adjust the ISO to 200 or even 400 to give you a balanced meter reading.
Another idea is to bring a stronger light into the setup, so that you can get a higher aperture (more depth of field) with the same settings. Also, if you want to obtain full-size reproductions with your photography, then you will need the Canon Life-Size Converter EF for about $242.
