I want to take photos of eye iris for iridalogy readings, what is the best maco mode digital camera without having to buy macro lens? My brother is an optometrist and he just asked me a similar question as he wants to make excellent photos for documentation of pathologies. We did tests with a Nikon D200 and D50 with a macro lens. We also tested various point and shoot cameras, including 4 MP, 5 MP, and 10 MP cameras. ALL of these set-ups produced acceptable results for his purposes, so I am sure that they would be good for you.
The best is any dSLR with a dedicated macro lens, but you can get quite adequate results with almost any digital point and shoot camera if you use it correctly. I gather from the previous answer (and an internet search) that iridology is not an exact science and you don't need a high pixel count camera. All you need is a camera that will get within 2-3 inches in macro mode - which is practically any P&S made - and a little experimentation to get the settings right. I think you will find that you need to set the exposure value (EV) to a negative number like -0.7 or -1.0 to get a proper exposure. After that, you're good to go.
I just took a couple of pics for you and put them on an FTP site. Go to http://www.members.aol.com/swf08302/iris... and check it out. The SD700-IS is 6.0 MP and the SD900 is 10.0 MP. Move your mouse so the cursor goes over the image and it will turn into a magnifying glass. Click it to view the images full-sized. I didn't even look in the mirror for these pics, but just set the cameras on Macro, guessed at a distance (my eye from the lens) and pushed the shutter release, letting autofocus do its thing. After taking the pictures, I just cropped them around the eye without any alteration in resolution so you are comparing apples to apples when you look at the results. If this is not adequate, you need to look into a dSLR. You're welcome. Person. (haha) Report It

seeing you want the best but not the best... I can't say Start comparing in your price range.
Best is going with a slr camera with a macro lens. I'd guess anything with a Carl Zeiss, Leica or Nikkor lens, and a high resolution format.
You have to experiment with manual lens openings to get the best depth of field and probably a tripod to eliminate camera movement. A manual focus override is a good option also.
Photoshop should offer you the color correction you'll require, so also include a neutral gray card in all your photos so you can match it.
Since iridology isn't considered a 'hard' science or an investigative medical diagnosis, all you need is a pretty color picture (in focus) on nice photo-quality paper.
Have fun! Canon powershot G7 $500 |
