Mike,
You do not need to make a copy of a jpeg before editing it. Edits to any type of file in PhotoLab are non destructive and are located in the database and sidecar files. They are only applied to newly exported files and not the originals. In that respect editing Jpegs in PhotoLab is similar to editing raw files.
Mark .
But when exporting the original can be overwritten. And then it’s goodbey.

But only if you deliberately change the default suffix. And using the name of an existing file for export does raise a warning. I would say it takes a particular type of idiot to ignore all that.
I don’t use a suffix under normal circumstances. And yes, when the file will be overwritten I get a warning whether to use an unique name. But that isn’t the point. The point is to be aware that a jpg can be overwritten, nothing more as a warning. Just a matter of take it or leave it.
By the way, my exports are always going to a subdirectory .\jpg.
George
You’re confusing me - when I export images, PhotoLab saves them in a folder inside the folder with my images, and inside a sub-folder named (in this case) PL5 Exports:
I assumed everyone did it this way, but maybe not. The filename remains the same, but it is saved in a different folder, so the original image is untouched.
As you see here, the Suffix is also changed to “_DXO”
And no the jpg file will not be overwritten on my Mac if I want to export in same folder than original.
When I do that I have the following popup:
So you have more options in Windows, lucky are you…
Well, I use all of them.
George
And we have the same on Mac when exporting raw to jpg for instance, and there is already a same jpg in the destination folder.
It’s true, one can’t overwrite the image for the image is in use by the program. It’s a blocking of the os.
George
OK, just to confirm, the difference between adjusting the gamma and adjusting the exposure, is that gamma only affects the dark tones??
Doing a quick Google search I found " Gamma is an important but seldom understood characteristic of virtually all digital imaging systems. It defines the relationship between a pixel’s numerical value and its actual luminance . Without gamma, shades captured by digital cameras wouldn’t appear as they did to our eyes (on a standard monitor).
Reading further:
Gamma
I need to re-read this slowly, maybe three times, and maybe I’ll eventually get it sorted out in my mind.
I won’t ask about it any further here in this topic - it deserves its own topic, where other people might find it useful. Maybe you or Joanna could start a new topic, explaining to the 98% of us who don’t understand, how and when to use the gamma setting tool in PhotoLab.
You and I think very differently - you suggest I play with it and see the results, while I want to understand it first, and only then start to play with it and experiment.
My best guess right now is that the gamma setting brings up more levels of dark tones, trying to get the image on the screen look more like what we saw with our eyes…
ARGGHHHHHH!!!
i am thinking of buying a gift for my daughters journey a LX100mk1
So she can take images in low light and better images on the day then her phone or my old fz200.
what do i stumble on looking on a secondhandwebsite?
an Almost new G9 with extra batteries!!
for 50% of the new price. Damnn!
and i didn’t looked for replacement of my g80.
ok it’s somewhat better in all directions:
4Mp’s extra.
one stop extra stabilisation
newer sensor => higher iso 1 stop.
more dedicated buttons.
higher burst speed and bigger buffer.
Dual Sd slot. (i think only mirror based as backup but didn’t looked at it)
heavier 150gr bigger (mostly grip)
better EVF and extra LCD on top.
voice right shoulder: you don’t need it! the g80 is not worn out or old and the g80 is good enough!
voice left shoulder: you have the money! live a little. it’s a hobby.
voice in my ear if i buy it would probably : why did you buy it? we could used the money for our new house to renovate/ buying stuff… 
i am on the fence here! help me out!
compare
Why not ask your daughter which one she prefers?
One is newer and more powerful, the other is smaller.
owh the lx100mk1 is for her but the G9 is for me! 
(The compare would be G80 vs G9)
(i think the G80’s menu is a bit too difficult to untangle when sher mesh up in far far away place so i can’t help out re-setting it properly. (yes i can set a C1-2-3 so she can return to memoried settings but stil she isn’t a experienced camera user) So that escape to justify isn’t a real stronghold in the discusion by telling she get the G80 and i have the G9. (and i have to let her take a lens of my collection with her journey…)
The LX100 is “mechanical” driven enthousiast camera with Aperture, Focus, and such all dedicated rings and buttons. not much to dive in to menu’s and screw up wile miss choose settings
Peter, I have & use that cam since years. With ‘careful’ handling of the raw-files it is no problem to use the pics for a photo book in A4 portrait format with so-called “Layflat-Bindung” (see here for examples).
Fully open the net size is 27cm high and 42cm wide – that is a nice size. I did so with pics from landscape & people, but also with photos I took in a oldtimer museum, not so well illuminated. The latter one was from 2016 – and no use of PL yet, not to mention the latest DeepPrime XD, which does ‘wonders’ for that cam.
Don’t wait for the last minute to get a(ny) cam, so that she gets used to it before travelling.
One simple question – did you try it or are you still reading?
I tried various settings on that one image, and I have just started to read.
I went through it quickly, and now need to slow down so I understand.
Oops, sorry. This might be a better link for a comparison:
