You shouldn't be living among these people then obviously.
What's a nice kid like you doing in a place like that?

Agreed you haven't given much info, but I'm going to guess anyway. You have been shooting in aperture priority?
A mostly automatic exposure getting the basically same type of results at various ISOs ?
Remember that studio lights don't change their intensity.
So you might do better here in shutter priority to vary the intensity of the light coming from the studio light.
It appears in this shot that if shutter a little faster it gets you a shot highlighting th edge where the wedge curves
and lessening the light just a bit on top of the wedge with a bit more definition.
If that doesn't do it for you, we would need info on how you are exposing your shot, and just how you want the
subject to look.

Wonder whether some folks sit around thinking up ways to "make photography difficult" games?
Just skin out of this exercise and shoot monochrome and be happy if colour irritates yuh...I never
knew colour to be harmful though. :)

Yep, never saw one walk around. Of course some people have a
"go to" lens also, gotta watch those or they might get away if not
being watched.

Then how do we REALLY know, since originally he said only that he didn't make any tapes himself, it doesn't mean
the staff didn't install the means to do it for him, and especially if maneuvering a visitor to the office in just the
best part to do it. It's not last half 20th cent. but 2017, and technology is quite amazing these days. Or, by
teasing with a delay for a month, some tapes might have conveniently disappeared...the behavior is just....
odd ...to say the least, misleading, or downright tricky?

There will be a chart with every one you look at in the store I'm quite sure, listing size, cooling
capacity per sq. feet..
First other consideration would be that it fits the window! If you go for lowest power for the room you
might have to be in front of it to stay cool in a serious heat wave.
Then if it's for a bedroom, or if a small child's room, you wouldn't want it blowing cold air directly
on a person. So would you be able to rearrange furniture? (There may be other considerations that
other people think of that so let's see what other suggestions they may have....

Wow, you've gone far afield with this one Brent. No water!!!
Not at all anything like those we came to know you for, here the
faucet doesn't even drip. Nice work!....but I would be a bit worried
there, as something happened to "dark", these people don't even
have shadows? Ah, looking back now, I see they do, relieved,
because "science fiction" is a bit disconcerting..

Thoroughly interested and delighted in the shots, all of them, from Union Station to the nightmare of making
up a freight train on that web of tracks. Sometimes grit and spots belong in a photo, even when we could remove
them. This was one of those situations. Sometimes a high ISO is wise or essential, whether because of action or a
need to get sharp in less than bright ambient light if ot on a tripod. Thank you for the treat!!

Well, don'tcha know, this is just the beginning! He's invited her to dinner, they take up residence in the yard or nearby,and
soon you will be photographing a little family!

They look so delicious....
If I pick them will it make a hole in my monitor?

Ok, seriously, I'd like to recommend mirrorless. Specifically, I have an Olympus, many folks recommend Sony. In either case,
travel, or project work, the image quality is excellent, they have great lenses, lighter weight to travel or work all day. It's
really not so much a case of larger being better anymore, the difference is quite insignificant or evidence lacking.. That said,
someone will surely claim otherwise and tell you that you might see a difference if you enlarge to great murals, and maybe
they are right, but then, do you really need to enlarge that big?

Another option, if you don't know what you want, just send the $2k to me :)

Referring back to the Op's topic and question then, he does not understand why 16x20 is not the same ratio as 20x24. Let's try to help him:
Both 16 and 20, can be divided by 4..... to get 4, and 5......and 4:5 is NOT the same dimensions as
20 x 24, as that gets you 5 and 6..... 4:6 . No one ratio will "translate" to another in some other size! You need to stay in your own aspect ratio.
Whatever one is the default ratio for your camera, or any other ratio you choose, needs to be in the SAME ratio to enlarge or reduce in order to fit a
standard size paper, (unless you want to pay for custom printing), and to avoid minimum crop.
So multiply to enlarge or divide to reduce by the same numbers for BOTH dimensions. What was your original starting point, i.e. camera's ratio
before you enlarged anything?
I notice that this thread is taking 2 different paths, those who print and those who send out, and further subdivided by those who send to custom
labs and those who go to Walmart. I think the Op wanted an answer for the local option. Maybe 3 different threads would cover this subject, and almost
certainly there are answers for everyone else in the search feature or especially in the printing sub-forum.

But they "got what they asked for". So I guess if they can't understand what they should be
asking for, they should just ask the printer to tell them what they can get in the aspect ratio
they use, rather than ask for what they "want". (Still, it's our duty to try to help when they ask
here.)

Yep that's what it is. They didn't know there's more to composition than
composition...... until they went back to the printer
