You need a planter? Crock for making pickles? Very small infant kayak?
Think f the possibilities for an unused printer ...
OR, you could panic and boil some water ...
I suggest you never carry a camera or a tripod or a flash unit or a string and washer ... instead cry yourself to sleep every night over the shots you missed. When crying stops working you'll turn to prescription drug abuse then alcohol then prostitutes ...
But whatever else you do, NEVER carry a camera!!!
I was on aperture priority at f5.6 with my Canon 100-400 Lens.
I got a 28-135 with my 50D a few years back, was very quickly my favorite lens ... but it too has issues. If you're in a dusty environment the 28-135 sucks dirt inside itself and as it builds up over the years you either have to get it professionally cleaned or plant a garden in it. Weird how my two favorite lens suck dirt, have to wonder if it isnt an omen.
I like your images fine the way they are ...
Couple of things you could try to improve future shots:
First shot - Show her eyes (at the least, one of them), even if they're closed. Captures emotion. A slightly lower perspective would accomplish that.
Second shot - Not sure what you were going after ... image seems scattered. Suggestions: light the cigar, remove her top too, express more similar or more polarized emotions, ...dunno really, can't suggest/help much on this one.
In the final shot I would have asked the dancers to look at a certain spot off camera ... the same spot for everyone. Maybe the back of the front dancers head.
Those are hard to flush too!!
I save anything I want to print in tif format with no compression. this gets the most amount of information to the printer.
Anything you save in jpg loses information from the original capture no matter if it's RAW, jpg or whatever.
Other than that I agree with the comment above about YOU doing all the post processing and showing him the product. Once he concurs, YOU get it printed by a pro and give it to him (in exchange for a tidy sum of $$). No matter who does the PP and printing it's still your picture and your name will forever be associated with it, might as well make it really nice.
ONCE I gave portraits to the (expert) client to work up and he screwed them every way from Sunday ... but my name was on them, never again.
"Canon Beach Rocks" ... well ... it rocks!!
I'm glad you didn't go into aviation as a hobby.
Composure, focus, sharpness, lighting. creativity and appeal ... wild guesses, did you ask the school?
I donated mine to a local non-profit a couple of years ago, good for them and a tax deduction. That's a commitment to digital!!
The AE 1 was my first SLR too, came with a 50mm prime lens and a 70-200 zoom, loved that zoom. You never forget your first time with anything ... LOL,
Now I'm saving up for another 70-200, only a 2.8 L this time.
Go out on the net and read several non-Canon reviews on the Canon 18-200. I did, at B&H and Adorama, and about half of them were bad ... not sure what Canon did wrong, but they missed the boat on this lens.
Wow to all of them ... just Wow!!
