Yes, in Module 4 (the "Tour") you'll find the bit about sRGB if you need it.
PLEASE don't wait any longer to step up to the Levels and Skin classes. They'll blow your mind.
Outside of class, only this: https://www.damiensymonds.net/workspace-video
Don't forget that raw will be set to Adobe RGB by default, so you'll need to change that to sRGB the first time you open a raw file.
There are lots of ways, of course. Here's a pretty easy one ...
Add a blank layer, then use the eyedropper tool to sample some of the yellower skin just under the eye. Add a Solid Color layer of that colour, and change its blend mode to "Screen" (which will immediately make the whole photo quite light). Invert the mask to hide that, then use a very low opacity white brush (eg 3%) to gently paint into those spots.
If you don't know the exact resolution, that's fine. Just crop it to the dimensions required, without imposing any resolution at all.
Will you need to allow some extra for bleed or wrap?
Let's put this nonsense to bed right away. That has NEVER been true. I don't know why this myth still exists.
You need to talk directly to the printer, to find out what resolution they require.
As you know, it's common for normal printing to be done at 300ppi, but that's far too high for this. It's more likely to be 100ppi or thereabouts.
It looks ok from here, but I'll need the 100% crop to tell for sure.
ALERT! DANGER! ALERT! You're working in Adobe RGB! That's very very bad. Make sure you click on the link at the bottom of the ACR window to change to sRGB.
Hi @kymater, yep, I can definitely help with this.
Go ahead and do your raw processing as usual, then post the photo again for me so we can discuss the shirt.
Oh, by the way, which version of Photoshop do you have?
Lightroom is utter shit, and I urge you to get a version of Photoshop or Elements pronto.
You can choose any profile that's on your system with the little app I described in this article. (You can also do it with Windows itself, but the app is easier.)
And now that I think about it, I guess one of the most poignant reasons is that some people prefer to save their profile with the date (thereby gradually filling their system with out-of-date profiles) and some people prefer to save it without a date (thereby replacing the same profile each month). Software that automatically made that choice for us would only please half of us, if you know what I mean.
