Imossible to do adjustments after using "click white" tool?

[hhvaal]

Hi, if I use click white tool to pick a white balance, I often get something very close to what I want, but just a tiny bit off. In these situations I really want to just make a minor adjustment to get the perfect result, but whenever I trigger that adjustment, the whitebalance mode goes from "click white" to "custom kelvin" and the color changes completely. Can I carry over the selected whitepoint from the "click white" tool into the "custom kelvin" mode somehow and then make adjustments on top of that?

Thanks,
Harald

Hello,

Just tested there : picked wb from an area of a picture, giving color T°=4519.
Then, went to the tool and adjusted color T° to 4560 : the display toggled from click white to custom, this is normal, but no value other than this one did change, and no side effect as well.
Could you give us more details (snapshots before, what you do, after) ?

Regards,

J.-L.

I wonder if it was a bug; I suddenly can not reproduce it any more. I will try to get a reproducible procedure posted should I see the bug again. (wonder if I might have been accidentally doing click-white adjustments on a JPG, which shows somewhat similar behavior)

[hhvaal]

I tried the same procedure with adjust from "As shot" whitebalance, and there I definitely see the same buggy behavior.

We start with one picture where the "As shot" white balance is clearly off:

Next, I adjust the tint +1 by pressing CTRL-SHIFT-G (I observe the color immediately going from way too red to way too green), then -1 again with CTRL-SHIFT-F. Now the temp and tint values are exactly as before, but the white balance mode is changed from "As Shot" to "custom kelvin". I expect the pictures to be exactly the same, but here's what I get:

Why does the white balance mode make any difference here?

Hi hhvaal

it is an old problem which has been already reported.... here I add an additional info there and sent the bug report to the monkey also more than 1 year ago ... Nothing was done.

As ASP seems to be dead I do not expect any correction but it s for me one of the really annoying bug

[ferdinand-paris]

This may not be any consolation, but I have same kinds of problems. The eye-dropper does not give good results for WB, and as soon as you start to adjust WB manually the white balance jumps and the image becomes rather green. What is happening is that a given temp and tint is producing an image with a different WB for As Shot compared with Custom. This should not happen and must be a bug. So getting WB right in ASP is a lot of hard work. Each image has to be done manually, unless you have a batch with the exact same lighting, and each time the program is fighting against you.

This is with Nikons. To be honest, I've never been happy with the colour rendition in ASP compared to B5. The Canon guys might be happier, but I'm not.

ASP is moribund, with no sign of any development, so I have no expectation that this bug or any others will be fixed. I've gone back to B5 for colour work where the camera is supported, and to other software where it isn't.

It always makes me sad when I consider all the potential that was B5 / ASP, which is rapidly going down the drain.

Oh, that sucks. I was really starting to get comfortable with ASP, and the other linux alternatives really do not compare at all.

Sorry about not seeing the other duplicate threads, but the damn search function in this forum wouldn't let me use quotes, and kept ignoring half of my search term because they apparently were too common.

[ferdinand-paris]

Oh, that sucks.

Ain't that the truth.

Hello,

To be sure, as I tried it once more and still no such behaviour : I'm currently using 1.1.1.10 (yes, the one with no NN anymore ).
Which one do you both use ?

Regards,

J.-L.

[hhvaal]

I have been resisting that update because I'm using NN as a RAW default everywhere... I'll try with the new version as well and see if it fixes it, but if it does, I'm still not sure if I will upgrade with NN going away

Are you trying out with the click-white tool, or are you doing it with the "As shot" switching as I mentioned above?

[FalCT60]

First, I just discovered that the behaviour is different whether working from the Standard tab or the Colour one.
Within the standard tab, Shift+Ctrl+G changes the tint but not any cursor value.
In the Colour tab, the Tint cursor moves accordingly to the keys depressing. End of the parenthesis.
1- I start from a picture with As shot settings,
2- I pick the white balance from an area, so the color T° (and tint, if within the Colour tab) is set up correctly, and the field toggles to White click (pipette des blancs).
3- if I depress Ctrl+Shift+G, the tint increases by 1 and I get Custom (personnalisé) instead of White click.
4- I can move each of the Temperature and Tint cursors as I want, then if I type the values that were displayed when picking the white balance (2-), I get correct display again as in 2-
I will give it a try with 1.0.1.30 when I'm home, and report what happens then.

Hello,

So, I checked with the version on my home computer, which is 1.0.1.10 (vs 1.1.1.10 on my way faster office computer) and still couldn't reproduce what you describe.
Picking the WB from an area adjusts both colour T° and tint and toggles to Click white, then depressing Ctrl+Shift+G decreases the tint value by 1 and toggles to Custom, with no important change, and finally Ctrl+Shift+F goes back to the picture displayed after picking the WB.
Moreover, if I move both sliders at any position and type in the values as they were after I picked the WB, the pictures becomes what it was at this time, and typing the values that were when As shot, the picture is as it was then.
This is on 2 totally different computers, both running XP sp3, BTW.

Hi FalCT60

it might be camera dependent - What kind of camera have you got ?

I have this problem with my RAW files of a canon 5D mk II (as well as the sRAW) - Can you tried with a RAW file of this camera? i ll be interrested to see if on windows you have the problem (you ve got plenty of samples on dpreview.

Thanks

Hello,

My camera is a Nikon D700.
I went to the pages, but could only find JPEGs there. Maybe me doing something the wrong way.
Could you provide me with a direct link to a RAW file ?

Thanks,

J.-L.

OK, me again, just to be sure I didn't misunderstand anything...

Ct'ed in next post... impossible to attach more thant 3 files.
