P: 12.4 color sampler/readout issue.

Hello,

 

Anyone experienced this issue?

Upgrading to Ligtroom classic 12.1, RGB color readouts were completly off on masks. Visually you could see the expected changes in contrast, brightness, etc while mouse over readouts showed the same numbers as before. So completly off. Like you could see that black areas were getting toward complete black, but the readout was still at around 14% in all 3 channels.
 
I downgraded my Lightroom to previous 12.0.1. which works just fine.

Hello,

 

usually on masks I edit exposure, shadows, highlights. Sometimes whites, blacks.

I have a constant workflow of products, shoot under exact lighting conditions and some colors have to match exactly (+ - 2%).

In 12.0.1 all was working well, in 12.1 not anymore. So I went back to 12.0.1

My RGB values changed, as expected with masks/exposure.

Still having the same issues even with Lightroom 12.4 and osx 13.5 (ventura).

It works fine with LR 12.0.1

I can't replicate on my Mac either. With or without a mask, the RGB values are identical in the same location. After creating a mask, what edits are you applying?

I cannot replicate this behavior in Lightroom Classic 12.1  RGB values reported under the Histogram adjust for masking changes.  Perhaps you could give us a step-by-step example?

Hello, i  wrongly replied to all in this chat.

Mu issue : I am adjusting still life pics, so that they are consuistant.

1. I import daily around 60 raw files, from canon r6.

2. Apply custom settings to each of pics (contrast, brightness, shadows, lights and red hue)

3. Zooming in i check the exposition values (RGB) on various parts of the products.

4. I draw a mask, cross select it with red color (which usually needs adjustments), so to select only red parts of the product. Many times i draw many additional masks, for different parts of red areas, if these areas are more in shade.

5. Usually i adjust exposure and shadows, so to get the red in RGB readouts at around 60%.

6. I check adjusted areas so that R from RGB is around 60 (usually is lower before local adjustments with masks).

7. I also darken other, too bright areas and lighten too dark ones, but there i don't need readoust, it is purely visual.

But for red parts i need to be consistent, so that R from RGB is around 60%.

This way all works well with LR 12.0.1

Today I did a clean install of osx 13.5 (ventura) on my Imac 27' (3,8 GHz 8-Core Intel Core i7 / 

AMD Radeon Pro 5500 XT 8 GB / 40 GB 2667 MHz DDR4). I also installed LR 12.4.

The problem persists . Visually the adjustment happens,  color readouts are wrong.

Downgrading LR to 12.0.1 it works normally.

I guess that something happend when reprogramming LR from 12.0.1 on.

Any suggestion?

Greetings, @Boris27771378e35s 

I've reviewed your steps with the engineers. Here are some asks:

  1. Do you see the same issue in Camera Raw as you do in Lightroom Classic
  2.  Is it possible to edit a file in 12.0.1 and export it as a DNG and then edit the same file in 12.4 and export it as a separate DNG and share both with us?
  3. A picture is worth a thousand words and video even more.  Is it possible to demonstrate the issue on video  (it would be most helpful to have a video of each version)

 

If you can answer/supply that, I can have an engineer evaluate it. 

 

Thanks!
