Guest guest Posted June 23, 2002 Report Share Posted June 23, 2002 I had been taking tongue photos for quite some time now. from my experience this are the main points i can think of: - DONT use a flash! - Make sure the lighting in the room is the same - i use close up lenses - use not less then 400Asa film - if you want a digital camera it will have to be a very expensive one - keep in mind that the main problem is with the colors hue, so recheck it with the real tongue.

You may be able to get decent quality with some of the cameras in the $800-1000 range, definitely nothing cheaper than that. Olympus, fuji and Nikon models in this range get pretty high marks from most reviewers. Plus you can store all your records, including photos, electronically. Good digicams will probably get cheap very rapidly, ala computers and VCR's. So waiting ,may be a good idea. Quote Link to comment Share on other sites More sharing options...

If you don't use a flash, then the photo will be too warm and lean more to a reddish tint. When using a flash, it should be bounced off a white wall or off a white cardboard taped to the flash with the latter being tilted to an angle away from the patient's eyes. An alternative to using a flash, would be to replace the lighting in the clinic to full sprectrum lighting (this should be done anyway. Inside lights are usually 3200 on the Kelvin scale and natural daylight is around 5500 same as a flash), place the camera on a tripod, open the aperture wide enough to get a good reading but not so wide that you loose depth of field, and hope the patient's tongue doesn't quiver Not sure if the above is true with digital cameras. ~Fernando > > > I was wondering if anyone has tried taking photos of patients > tongues and > > > what equipment they used.

Guest guest Posted June 24, 2002 Report Share Posted June 24, 2002 Hi, yes I am still on the list. I personally have decided against a digital camera, because the quality of the slides- when required for printing- is much better. For this I use a special camera from yashika which is designed just for the mouth. (Some pictures in the tongue book have turned out to be slightly to red. This was due to problems with printing. The second volume has just been published and although I have used the same camera, the quality is much better (german edition) due to the fact that the printers have new printing machines and scanners have much improved. I think for teaching purposes or reference a digital camera is a good idea. Barbara K Quote Link to comment Share on other sites More sharing options...
Guest guest Posted June 24, 2002 Report Share Posted June 24, 2002 Digital cameras are nice in that they need very little light and that's a plus in most treatment rooms. Also, make sure that the pictures are taken in the same lighting conditions for everybody. Then, any changes made to the color and hue balance of one should be made to them all. In photography, we often use a 22% gray slate to calibrate the density or saturation on the images. You might consider buying one from a photo shop. Also, Barbara Kirschbaum used to be on this list, might still be. Her book on tongues makes use of much of these concepts. -al. dany_lv wrote: > > I had been taking tongue photos for quite some time now. > from my experience this are the main points i can think of: > - DONT use a flash! > - Make sure the lighting in the room is the same > - i use close up lenses > - use not less then 400Asa film > - if you want a digital camera it will have to be a very expensive one > - keep in mind that the main problem is with the colors hue, so > recheck it with the real tongue. -- Al Stone L.Ac. <AlStone http://www.BeyondWellBeing.com Pain is inevitable, suffering is optional.

Guest guest Posted June 24, 2002 Report Share Posted June 24, 2002 Hello Rich, When I worked at Emperor's, we had a practical portion to our comprehensive exam, similar to the CA state board. We would take pictures of tongues and faces with a regular camera, no special equipment. They didn't always come out mostly due to developing. It didn't really matter because we could write any story we wanted to. This was before digital cameras were around. If you can get accurate color using the digital camera, that might be best. I would try taking them outside, out of direct sun. Or if inside without a flash but it is difficult to get the lighting right inside.. Hope this helps. Good luck.

What you need is a ring flash. This will give you a consistent light source, without hard shadows, and will allow you to use high apertures and low film speed (asa), thus sufficient depth of field to give good image quality. It will also avoid camera movement and subject movement. With available light you have none of these advantages, and probably have images that break down with any degree of enlargement (eg for reproduction, or a slide show).

Guest guest Posted June 25, 2002 Report Share Posted June 25, 2002 I've heard a couple of mentions about digital charting. I'm not familiar with that system, could anyone enlighten me? I was also interested in using a digital camera for taking tongue pictures. I was working with an expert in digital cameras who works for Adobe, and he told me that the megapixel rating would not be too important. He gave me the dpi (dots per inch) that the publishers printers could print at, and it's not that high. I seem to remember that the minimum was 890k pixels for 3 " pictures or somewhere around that. I do think that for cropping and enlarging that particular section of picture will need additional pixels, so a 2 mp camera should do fine. I was primarily concerned with color rendition, and someone mentioned to use a color card. That's a great idea. When looking around for cameres, I came across this website, where you can compare color bar samples on various camera reviews. You can see there that the color reproduction varies quite a bit! The website is: http://www.dpreview.com/ I think it would be great if someone could setup a web page to upload sample tongue slides on for comparison and analysis.

Guest guest Posted June 29, 2002 Report Share Posted June 29, 2002 Dear Richard, I am just about to begin taking pictures of my patients' tongues and attaching them to my digital charts. I've already done a few 'pilot tongues' to check for color accuracy. I think it is very worthwhile. I will be a Dimage Minolta digital camcra hooked up to my Powebook G4.
