Hi Greg,
see some of the videos by the time and found Arts hint about the picked and inverted color for removing a color cast.
I remember you told us about the photofilter for that. Don't really understand it.
Why not picking the existing color of the cast from somewhere in the picture?
I had a short try and found it works nice for a beginning.
It does work but....
If you choose the wrong spot for the color picker you will introduce a false color cast that is worse than the one you are trying to cure. Not every picture will have a good place to select the color from. It is a solid process and one you should try...it just may not always return the correct hue.
Absolutly! It could not be any point of the picture.
But what point is maybe a good one? I tried with something, which has to be more white.
Maybe this is the only option for this method and don't works, when there are no whites?
One more question about getting color neutral...
Told before from this little hdr-contest in a german forum. I worked on a picture with a horrible color cast by bringing the three pictures together and then try to correct the colors in cm, which was very complicated and don't bring a good result.
After this, I try to set a neutral in all rawfiles in cr and had a much better result with just one neutral to go on in cm.
It's a mirracle to me and not everytime the same. Some Tonemappings work better with a color correction after.
Do you have an idea why?
Tone mapping in HDR is really an interesting process if you use a HDR program some of them can really over saturate the image and any color cast is amplified.
I would not do any color correction on a HDR until I had the file out of the converter and flat into Photoshop. If I use the raw converter and adjust the color of the image I would want to be sure I was not adding color cast to the frame.
Don't try it on the HDR, but on the sigle raw-files before I put them together.
In this special case, it was much easier to remove the most of the color cast and doing the rest in cm.
We have here in germany a growing group, who prefer to do most of corrections in the raw file, because of having all informations about the picture. The results mostly speak for itself.
I'm not that technical, but starts to think about lower information for correction and maybe borders of it.
Knew, there are another fraction too, who says, that there are no seeable difference.
Of course it is much more comfortable to do a color correction in cuvemeister, but in the told picture I failed totally with a lot of work in cm and have that nearly right colors with one klick in the raw.
Very confusing...
We also find out that different HDR-programms brings different colors as the result. Set a programm like that an own neutral point whithout asking maybe?
I tried the ps-own HDR-Pro and HDREfex for comparative. Last brings totally wrong colors. Black went to blue.
Each HDR converter adds color in their own way. Each interprets the file data and predicts a result. You might have to find one you like and stick with it.
Oh, okay. So I always have an interpretation of colors with every hdr-programm?
Even if I hit the right neutral in the raw, something other might be come out?
Wow, complicated!
By the way: My ppw-panel don't work very well. Don't get the helpful options most of the time and some actions don't wanna run mostly.
Do you have same problems?
I have had few issues with the PPW panel. What version of Photoshop are you running? It really likes CS5.5 or higher...
Hmm, have to think about an update. I have CS5.
New lenses are more important. So I have to do more manually, when the panel don't want to work.
Annoying. The options are great and quick.
But not bad to know, how it works manually..
Oh, by the way...
In this little hdr-contest, I told from, I don't had a ranking before this course.
By the time I came from third place after the first weeks of cm-course to second place and now the second time winner.
Speaks for itself, I think.
Greetings, Tanja
