Develop Persona for RAW Image: Mask for Vectorscope?

[Seikilos]

Hi,

after I learned about vectorscope for skin tones I want to use it everywhere, where skin is shown. Super useful tool without mingling around with color calibrated EIZOs anymore 🤔😅.

Now when I have RAW files in the develop persona of AP2: Is there a way I can mask out most of the image?

I see the vectorscope skin line but since I cannot mask out everything, that is not skin in the image, it makes it harder for me to find a good adjustment, when in the develop persona. Masking in photo persona and then going to develop seems not to honor the mask

Hints appreciated

Just do the adjustments in Photo Persona where you can use masks.

The Overlay Brush Tool kind of works as a mask in the Develop person but to be honest you lost me at Vectorscope

I have raw files, which I develop. Using photo persona is not convenient because accessing all relevant RAW image operations is AFAIK not possible there

Check these last 2 minutes (just hit play), pretty cool thing. Vector scope is great before applying color grades or if you want natural skin tones. Works in video as well in photos.

You normally do only basic edits in develop persona, and then switch to photo persona for the rest, especially grading of skin tones, as shown in the tutorial video.

I basically agree with this statement but changing exposure, blackpoint and adjusting the white balance temperature and tint is much more convenient in develop persona when dealing with RAW files.

My current solution is actually using the crop tool in develop persona. I wasn't aware that this is undoable when I click the hand again and allows me to actually crop down to skin tones, adjust them and then manually recrop to original size, all in develop person. Cropping back to 100% is a bit hacky but worth the pain.

Nice trick.

Actually, you can add a mask in Photo persona, nest it to the raw layer, then go back to develop persona. Histogram is the restricted to masked area, i could not try scope (currently iPad only).

Didn't work. The vectorscope when dealing with RAW seems to be applied to the pixel area, which does not consider the mask.

I've been working with vectorscope for non RAW files exactly like you mentioned. But I always remained in the photo persona.

Actually I've broken the vectorscope now multiple times trying to do the thing you mentioned. As soon as masks are in a RAW file the vectorscope sometimes just stops updating altogether even rendering the wrong scope (e.g. histogram lines with vector scope image data). Very weird.

Seems like I've found a dark place in AP2 that could use some maintenance 😅🤷

Hi @Seikilos,

I have a background of processing my B&W film and printing the negatives in my own darkroom. The way I treat the Develop Persona and raw files is I think of the Develop Persona as the chemicals used to process a piece of exposed film to turn it into a negative. Then I use that negative to make a print, I would choose the paper and an exposure time and developer for the print. It is a two step process, make a "negative" then use it to make a "print". Develop Persona then Photo Persona.

Think of the raw file as the exposed film, the Develop Persona as making a negative and the Photo Persona as "printing the negative". The beauty is that I still have the raw file which I can process again to make a new "negative" with subtle or wild changes to it.
