Hi, Drew,
I had intended to post this not in the "COLORRIGHT Sales and Support" forum but rather in the "white balance tools discussion" forum, but I can't seem to find that (wonder where it went?), so excuse me for posting here.
There are at least two basic approaches to white balance measurement with a diffuser-equipped camera that are widely discussed. One can be briefly described as a measurement taken "at the subject position", and the other as a measurement taken "from the position where the camera will be for the actual shots".
You and I have of course had some debate over these two basic techniques. I have described a principle under which we should expect the first one to most reliably provide the information we need, and you have assured me that the second is just as worthy of consideration. (At least, if the diffuser in effect is a Color Parrot/ColorRight diffuser).
I note that in the current on-line literature for the ColorRight diffuser, there is no mention of this distinction, nor really of the mode d'emploi at all. The pertinent part of the description of use says only, "Hold COLORRIGHT over lens & take one photo".
Thinking that perhaps this matter would be treated more completely in the instructions for specific cameras, I went to your on-line instructions for the Canon EOS 20D. There, with regard to the overall procedure, you suggest, "Take 1 photo".
Perhaps just what one is supposed to "take a photo" of is clarified by other material to be provided with the product. There was in fact some discussion of this in the card included with one of my Color Parrot diffusers.
Or perhaps it doesn't matter. The photographer, could, perhaps, take a "photo" (of course it is hardly a photo with the diffuser in place) of any handy thing on the field of battle.
What am I missing here?

Dang, that's confusing.
What are you asking?
Which is the better method to get a measurement?
or
Why it states to take one photo? And of what?
Taking one photo is in regards to the scene you'll be needing proper WB. In some cameras the reading comes from the most recent photograph taken and you take an actual photo. The camera uses this as a reference.
Of course, when you change scenes and/or the lighting/ color temp changes, you'll want to make another reference shot. | | | | | | Re: ColorRight diffuser - basic technique

My point is not that I want to know. My point is why does the manufacturer give no hint as to how one might want to use the tool?

Hi, Drew,
My apologies for having thought that the White Balance Tool Discussion forum had "disappeared". I guess I was just not looking close enough and under the right category.
Best regards,

Oh...perhaps I read it too quickly. The way I understand it is we have basically two options. subject to camera area or from the camera/ reflective.
The options give you a bit of flexibility, while the overall design is to be used in the reflective type method. Hence the design for use at events and such where getting anything up there by the subject isn't feasible.
Are you basically stating the instructions are not clear enough to the average user? I'm certain some modified instructions will appear with the change. I'm sure you know it's not feasible to instruct for every manufactuer and every photographic situation.
My question to you would be how else would you word these instructions? What is lacking in your opinon? I understand you write and are very detailed, however those type of instructions would leave the average user confused. Like me for example. I understand about every other word of your reviews. It makes my poor head hurt. I admire your knowledge and time you take to do this, however. For many, it is great knowledge to fully understand it all.
I must've read your post too fast without my spectacles on. ha ha. | | | | | | Re: ColorRight diffuser - basic technique

| Well, here's one possibility: 1. [Make camera settings as appropriate to make WB measurement or take WB reference frame]
2. Hold the ColorRight diffuser over the front of the lens.
3. Place the camera at the subject, aimed toward where the camera will be for the actual photograph(s).
4. Take the WB measurement or reference frame.

Hi Doug,
I think you have a revised set of instructions that came with the last unit I sent you. These instructions point out both methods, although I think I steer clear of the words reflective and incident, or whatever else we may wish to call these two methods.
We plan to update the website to reflect something similar in the near future. In the meantime, all units will be shipping with a similar set of instructions with the unit.
Hope this helps. | | | | Article Tools | Search this Article | | | | | Display Modes |  Linear Mode |
