Spiders are tough to get a good photo of, which many members have already done, this is a female Wolf Spider with her offspring ready to be let loose to hunt in the yard.
Arun, rather than commenting much on your photo, I would like to address the issue of how you might be able to improve your macro shots. You have a good camera and lens combination, but in your comment you said, "the camera is constantly fooled". I'm assuming you mean that the AF is fooled? Focus manually. You listed in the camera data for the picture that you used automatic shutter speed and aperture. I would suggest you try manually setting at least your aperture. For a macro shot, you want maximum depth of field. You have to have a fast enough shutter speed to stop your subject's movement, and that's a trade off. You complicate matters significantly when you use a flash, and proper flash technique takes some time to learn. I'd suggest trying to keep things simple, use a tripod, manually focus, and set the aperture to f16 or so, and I think you will be pleased with the results.
Thanks Harry,hence me putting it in the photo help category, the whole roll because of the babies had either eyes or offspring in focus, there must be a way....I know Nat Geo had troubles taking shots like this, the camera is constantly fooled. Onward an (hopefully) upward.I am primarily an underwater photographer, I find it easier.
Nice shot Arun, but it is good that you did discribe this as a spider with youngsters on her bag because otherwise we would not have seen this. Background colors are matching to much with those of the spider and because you did take a shot from aside the only thing to see are some legs. Depth of field is very small taking macros so it's very important to show as much on a photo as possible. In this case it would have been better to take a shot from the front so the spiders eyes will be visible ore a bit more from above to see the little ones on her back, Nevertheless nice try.....Best regards Harry
