Nice comments!

The wife crazy comment was related to asking her about hues and red/green and tint questions...

So with the x-rite you have, you only use the grey or white point and not the other colors on the chart?

Am I right that this option  http://www.amazon.com/dp/B002NU5UW8/?tag=googhydr-20&hvadid=14123715355&hvpos=1t2&hvexid=&hvnetw=g&hvrand=11235267231475335855&hvpone=&hvptwo=&hvqmt=b&ref=pd_sl_2m2w85pyb7_b   would really not be needed because I have profile prism?  And there is the QU camera profile....so really two options.

Sure I could use it for setting WB with the dropper but couldn't I use this option as well?

I really like the idea of using the photovision 14" target to get the exposure right and not blowing out the highlights too.  I'll probably have $125 in all three of these tools (expodisc, target, and vello).  Seems reasonable.

I appreciate your dialog.

I only use the grey patch that is 200,200,200 (under the correct lighting), for "grey balance".
Those Velo WB cards may be ok. but I had some that look very similar and they are not accurate. They are cheap enough to try out though.

That is probably over the top!
I rely on using the histogram view on my DSLR; it has highlight warning too but that is a little pessimistic for raw images, ok for jpeg.

Hi Terry,

Do you have any particular gyre cards/brands to recommend?

Also do you profile your camera?  Use QIU provided profile?  Use profile prism to profile under various light?  Or use something like the industry standard x-rite passport?

Thank you....

Sorry, no. As I said I use an X-rite mini checker, handy as it's pocket size.

Yes, my camera is profiled for use with QU raw. I made my own profile with Profile Prism which uses an IT8 target. I sent my target image to Mike who used it for the 600D profile available from DDI.
Making a target image for a camera profile with Profile Prism is done with full direct sunlight. Care is required to avoid any reflections on the image and if you have PP and want to do it, Mike will send detail instructions on request. If you have an IT8 target you can send a target image to him who will than make a profile to publish on the DDI web site.
