den , your 'suggestions' are quite appropriate and deserve a brief review with each new hiking experience. Fortunately, we came here over 20 years ago with a mindset to never let these surroundings become commonplace. As of today, at least, we have managed to maintain this attitude and continue to ...

Den, my weird sense of humor and reaction (" easy for you to say... ") is superficial and not at all indicative of the level of interest and concern I have to produce images depicting scenes .... as I saw them . You and select others have shown an amazing level of understanding of complex ...

Hi Den, Tried Sigma's SPP 3.5 Auto Raw conversion mode and sky color definitely moved more toward the Ricoh and Nikon. Mid-range boost is apparent in all of Sigma's files, but I have factored that into my posted concerns. I must do some more tests at sunrise and sunset since sun's angle and use of g...

Thank-you Keith. I have reviewed WhiBal several times, but had no basis for choosing their solution versus some respected others. Perhaps their Studio size will still work comfortably for my hiking needs and offer more surface area to use in PP (if variations_reflections_etc. are present on the card...

Sincere thanks for adding your valued perspective. I'm feeling the larger (foldable) White card will be most helpful in landscape images like the one I posted in this Thread. Most of the scene is far from the lens and perhaps getting the card further away, and still a reasonable fraction of the tota...

Jonathan, I do appreciate your comments and clarification. I will definitely do some very similar tests using a white card, although still facing the same size constraint (for hiking) and desiring one which I can 'protect' from damage. If there is an ideal 3" x 2" card ( or larger to be cu...

I appreciate the support received and accept that the issues I posed are not easily solved in the context they were posted (ie. easy gray card, colorchecker, WB, 'fixes'). I am now left with reservations about acquiring and using either the X-Rite Mini ColorChecker card or Passport product .... spec...

Thank-you for the explanation and ideas. Based on this analysis of the issues, are you also inferring that a ColorChecker in these images (or taken sequentially) will not add value in the context of 'correcting' or 'normalizing' this type of image .. when post-processing .. ?

Thank-you,

Here are examples of the problem I'm trying to deal with. All taken on tripod, very comparable settings, all within a few minutes, and all using a separate gray card image for WB. All converted from RAW with only WB adjustment and saved as 16-bit TIF .... resized and saved as JPG. I expect Sigma's F...

I wil be purchasing X-Rite Mini-Colorchecker (Card only) ~$50.,or Passport (cards AND profile software) ~$100. for Custom WB and RAW PP of hiking image files from new Ricoh and Sigma compact cameras. When processing the colorchecker image, will PWP5/Color/MatchReference transformation accomplish the...
