Photographing human eye

iskoos · Feb 24, 2010

I tried to take a picture of my eye last night and the result was not so bad for no flash/ambient light conditions. Pictures came out clear but when I view the full size image, I don't see the sharpness I wanted right on the iris.

I used my Canon 500D with its kit lens 18-55mm

At Av mode, I set the aperture as f/5.0 (I tried stopping up and down from this point but I always got the best result at f/5.0). Shutter speed was around 1/50. Due to the ambient indoor lighting, camera was running at 1600 ISO but I really didn't see so much noise.
I was using center focus point. Camera was on tripod and shutter was set on 2sec to prevent camera shake...

Again, it wasn't so bad but still not like the ones you see online.

Am I missing anything important? Do you have any suggestion for me to try? Would a 50mm prime lens do a better job?

BTW, I don't remember exactly but my focal length was around 40mm

It would be alot easier for us to help you out if you post samples of your shots. It gives us a better look at what your talking about and what can be improved.

I posted to see if I am way off with my settings. I understand seeing the picture would help better but let's just pretend that I asked this before my attempt. Or let's say I would like to know if there is a basic set up to start with.
Posting picture is not possible at this time. So if anyone can contribute/advice(about ligthing, flash, lens type, focal length, aperture etc...) without seeing the pictres, I would appreciate. If seeing pictures is a must, then I would understand that too...

Thanks

Shutter speed. Get to at least 1/100 in AV. 1600 iso is high as well. Go outside, or next to a window if needs be. You just need a greater light source.

Advice taken... I will try to reduce that ISO by increasing light source. Will give it another shot this weekend.
I just want to get it done as best as possible with the equipment I have...
