Macro Photography Tutorial

Questions? Go here: www.youtube.com Basic tutorial on how to do macro (closeup) photography. FAQ Question: There are so many macro lenses, what’s the difference? Answer: Every focal length differs in working space. The shorter, the lesser working space you’ll get. The longer, the greater working space you’ll get. Focal lengths of 60mm and shorter has an disadvantage: at 1:1 magnification, the front of lens will have to be so close, which will block the light. Question: At 1:1 magnification, will the subject appear differently on FX format than on DX format or vice versa? Answer: Nope, the subject size remains unchanged on both sensor formats. DX format is “cropped” from FX format, which makes the subject to appear larger. Question: Why do you have to cover the viewfinder? Answer: To prevent spray light from leaking onto the sensor. It’s recommended if you’re using a slow shutter speed with a high sensitivity. Question: Can I achieve this with a normal lens? Answer: No, most normal lenses don’t have magnification ratios of 1:2 or 1:1. If you can’t afford a macro lens, use your current lens to take photos at its minimum focus distance then do some tight cropping.
