Hey everyone, So I've had my Sigma 105mm for a couple of months now but haven't really used it for Macro until this past weekend. I went out, took some pics of a few flowers in the garden and caught a caterpillar too. My question for thos who do macro is, How do you get so close to the bugs/insects? I have seen some great shots here that are right up to the bugs face. Is it because the pictures are cropped and zoomed-in PP? Macro is all new to me so some pointers or advice would be great - Thanks!
