WB correction suggestion

what would the community suggest as an aid for correcting wb? im currently using the gray page from kelby's LR3 book, which i fold and tuck into my bag, and whip out before i shoot. its a bit flimsy, and i get plenty of confused looks when i take it out and ask someone to hold it so i can set custom WB

i was looking at the expodisc, and some of the other gray card aids. with a card though, i feel like its the same issue as with my current sheet - having to fold it and tuck it into my bag. the idea of an on-lens aid sounds appealing, but they are pricey.

what would you recommend?

I've gotten great results with the expodisc but if you're using flash then it's almost moot.

is the expodisc worth the premium over the other aids?

I use colorright pro.

I did a comparison a while back between the Expodisc and a generic brand. While the differences were sbtle the Expodisc produced slightly truer colors to me.

Shooting in raw format where WB in the camera only impacts the jpg thumbnail, not the CR2 file contents. Then in LR or other tool you can adjust temp (blue-yellow) and tint (magenta-green) all you want without altering the CR2 contents.

I always shoot AWB with picture style of Neutral. This gives me jpg thumbnails and histograms that are as close as possible to how the CR2 file will appear in LR prior to adjustments.

If your going to shoot jpeg, have a look at the Brno Balens WB cap, all you need to is take a shot with the cap on then use the image to set the custom WB, very easy to do.

i shoot RAW, but often find it hard to find something in a series of images to use to set custom WB. for those that correct in post, do you then use one of those pocket sized grey-cards? how effective are they

I have tried the expo disk and found the results so so, I have been using the WhiBal card since last year and have had good results. http://www.bhphotovide​o.com …White_Balance_S​tudio.html.

I use this photovison target to set exposure and WB.. works great!
