A question about digital scanning, and printing plus why I didn't become a Rock photographer... [View all]

Story first (and applicable)

So, I love making art, and taking photos! 🎨 📷 I also love live concerts (various styles). One of my favorites is Rock.

I've taken occasional photos of bands I really like, to seriously following, and photographing my favorites through decades ; depending on how far away my seats were. I used to sneak my SLR w reg, and telephoto lens into arenas! 😄 This was when they were serious about limiting photography. I was very, very good. (rare now since 10's bc $ issues, then still concerned w Covid). I think I would have done well.
One of my photos even won a contest from a modest (not the most well known) Rock Magazine (not like RS, or Creem, etc).

But 1) I originally have so-so hearing, and permanent tintinitus in one ear from a show when I was 16. (not the worst kind that drives 😔 some folks round the bend!) So that wouldn't have been too good to excessively expose them even more even w protection. 2) l didn't want to sit through bands I really didn't like 😄 bc at least to my thinking - that's what It'd take quantity wise to make a partial living at least.

So to my questions. 🙂

While somewhat grainy (Tri-X 400 pushed to ?1200) depending on blowing up a section - I have some wonderful B&W photos of The Who from their 🧡 Who's Next Tour 1971.
My Art College let any student use their Photography Lab, even in the summer time! I got film professionally processed with contact sheets bc I hadn't yet learned how to process a film roll. And w something that precious to me; even if I had learned I'd let very experienced people take care of it !
Some time over that summer I lost 3 of my 4 rolls of negatives! 😫😭😭😭 The 4th one I still had was the further away one.
The only 2 lucky things were 1) I'd already printed a bunch of my favorites, 2) I don't think anyone found them, and made prints, and sold them bc I never saw any in all the rock mags back then, nor local newspapers. (I could be wrong, but I once saw on FB a photographer like 4-7+ yrs back mentioning they hardly saw photos from the WN Tour, and he had taken some if anyone was interested.)

Besides from the obvious action of taking them to a professional - I could have these contact sheets digitally scanned, right? Then what? They're on a SD Card? I upload them to a computer: pick out, zoom in a bit if I want, compose, and print - right?
(I've made digital art on a computer, and composed, and printed my later in life: various kinds of subjects using digital photography, Including Rock- like U2).

Tia!
No rush on answers; gonna to take a good while to save up anyway if this ( I hope) is a viable option.
