Copy adjustments from .arw, apply to .jpg, the reset .jpg

powul62
Out of curiosity..

I have this RAW file (Sony .arw) and .jpg
The camera shot in both filetypes simultaneously, i.e. shooting in raw and jpg

I noticed that the RAW (.arw) file showed slightly warmer colors, actually, compared to the jpg a bit unrealistic.

What I did and just to see what would be happening..

select the raw file, i.e. with the warmer colors
clicked on copy adjustments (note: I did not adjust anything...)
select the jpg
apply adjustments
seems nothing was happening

so I wanted to 'reset' the jpg to revert to its 'untouched' version so to say: rightclicked on Reset.

One way or the other the RGB-levels graphs of the 'reset'-jpg are changed compared its 'original' version.

Again, I did this just out of curiosity, but I wonder.. is this correct? (changed rgb red level)

Thanks

    I am afraid I do not see the difference in the histogram before and after the reset.

    Hi,

    if you copy any adjustment where actually no adjustment has been made (defaults) then in the process of copy (the copy-to-clipboard-icon right above the item) you need to activate in the shown dialog box the marking box for the corresponding item. If you've made already a change, pressing the copy-to-clipboard-icon will show a dialog box with box already marked.

    BUT the transfer of WB adjustments from a RAW file (with its normal default "as shot") to a JPG file doesn't make much sense. In the JPG file you have the WB from the camera already embedded and even if C1 allows some tweaking, it's not the same "liberty" in changing the WB as in a RAW file. For this reason JPG files show a default WB value of 5,000 INEDEPENDANT of the real lighting situation, whereas the RAW file shows a WB value which is normally the metered AWB value as determined by the camera (or one of the preset values as selected on the camera). But this WB works essentially only as a tag for the screen preview and can be adjusted freely as required (not sort of "hardlinked" to the representation of the colours).

    Concerning the possibilities of tweaking the WB of a JPG file I think the best idea is simply testing. At any moment you can get back to where you started by simply pressing the "return" icon above the WB section (or the general return key)

    Also @Michael11
    Sorry for the confusion. Shame on me, but got lost myself as well. ..
    Initially caused by a much 'warmer' color raw-file compared to the jpg shot at the same time.
    I started experimenting - how would it be if at all possible(!) when I were to copy the RGB levels
    from the raw onto the JPG.
    (never tried it, I wouldn't know if this would be possible, I guess it can't)
    After reset I mistakenly -thought- the rgb levels of the jpg were somewhat changed, you are right, they aren't.
    The orange vertical line in the levels graph was on another position, so I thought it was changed... 🤭

    Again sorry for the confusion.
    Ahum..

    One of my cameras (the one that I always have in a pocket on the principle of never going anywhere without a camera) is a Canon S110 compact. For various reasons, I shoot RAW + JPG on that camera. For a while I worried about the fact that the colours in the RAW files as rendered in Capture One were not the same as in the out-of-camera JPGs - they were generally more saturated and in particular blue skies were rather different in hue. I spent some time trying to adjust the RAW to look like the JPG. I even enlisted the help of Phase One in a support case. They helped me see how to achieve the same blue sky look as in the JPGs, but also persuaded me that the JPG out of camera is not necessarily "right". After that I took some photos with blue skies in them and made a careful mental note of the colour of the blue sky. I discovered when I got them on to the computer that although I quite liked the blue hue of the sky in the JPGs it was not in fact the actual colour that I had taken mental note of, and the RAW rendition was nearer to what I had seen.

    Just shared as a cautionary tale - you may want to do something similar and ask yourself which is a more faithful interpretation of the scene.

    Never mind. Just come back for another question next time. Have fun! 😉
