G3 for OR pictures

[bak5e]

Any suggestions for macro work in an operating room. I've tinkered with the various WB settings, flash, ND filter, etc. and have gotten very variable results. Center -weighted metering seemed to do best, but had unacceptable overexposure on lots of shots using the flash with the birght overhead lights. Ideally, I'd have one set of settings programmed into C1 and use it almost as a point and shoot in the operating room. Thanks in advance.

bak5e,

What flash are you using, built-in or external? You may want to consider using Canon MR-14EX Macro Ring Lite as shown on this review page: http://www.dpreview.com/reviews/canong2/page5.asp .

I have tried to use built-in flash to take some macro photo of my eye. I used evaluative metering and -1/3 flash compensation. I did set the zoom at most tele position. Here is a picture I got.

Good luck in your searching. Let's know what you find out.

Zow, I hope you don't plan on doing many more of those shots. Can't be good for the eye! =O

That's a good example of what the G3 can do in macro though. I can't get nearly that close with my G2 (unless you cropped the image).

To bak5e, do you have some examples of those problem shots along with EXIF data? Maybe we could figure out what went wrong. The macro ring light should work very well for you, but it's quite expensive and there's probably an easier workaround.

Are you actually shooting in the sterile field? Is the room dark except for the surgical lights? I would suggest you set the WB for tungsten, but you will probably need to consider the primary light source. I've seen guys operating with the overhead flourescents on and the surgical lamps. The surgical lamps are probably halogen. I wouldn't think you would need flash with all the light. Maybe there is a spare Luxtec headlamp you could use so wherever your looking you'll have light. What type of procedures are you photographing? With my G2 I rarely use the flash for any closeup work.

The room is bright with flourescents even without the spots on - I usuaaly have been using the high tungsten WB setting. When I've shot with a headlight on the field (halogen) I hopelessly underexpose whatever isn't "in" the headlight. Ideally the flash would act as a subtle fill flash. Also, is it better in macro mode to be as wide and close as possible, or stand back and zoom? Metering mode? All of this is head and neck - some cancer, lots of plastics.

Are you using flash. The camera's flash is ill suited for macro work. A ring light is specially designed for this purpose.

Seems to me that you would want to avoid a flash lest the surgeon flinch. But seriously, so long as you can use the ISO settings to help adjust clarity and depth of field the G-2/G-3 by providing manual settings should fit the bill. Just make sure anesthesia is not using flamable gases lest you spark and make major headlines...
Good Luck
