How do you get a jpeg with the long side at 10 inches at 72dpi to be 2000 pixels? I'm applying for an art show and that is the specification

How do you get 10 inches at 72dpi to be 2000 pixels? I know there's a trick, but I forgot. I have photoshop. If I use "image size" I get 10 inches at 72dpi at 720 pixels which I worry is too low rez.

Correct answer Tamara

I texted the curator of the art show, the specifications were an error.
I would like to delete this question, but I don’t know how.

Don't worry about deleting it. It's good for other people. I've seem a lot of questions from others regarding this issue, all basically the promoters having the wrong info.

Can you type or paste the exact text of the competition size requirements here? Are they requiring the 10 inches, the 2000 pixels, and/or the 72 dpi? Or is that your image starts out 10 inches wide?

Because it’s mathematically impossible to have an image that is 10 inches long, 2000 pixels long, and 72 ppi (dpi). You can have any two of those, but not all three. That’s why Image Size says what it does: It can only give you a mathematically possible answer.

The standard formula for resolution is:

pixels per inch = number of pixels divided by the number of inches

Image Size uses that exact formula.

2000 pixels long side is a very reasonable minimum requirement for, say, a photo competition.

720 pixels is too small for any such purpose! That’s what a web-sized image used to be with older low resolution screens.

You can upsample to 2000 pixels, but I can guarantee it won’t look good. Traditional upsampling will look grainy and mushy. AI upsampling looks immediately impressive, but is in fact very easy to spot because it is too plasticky perfect, with giveaway added details that usually look very artificial and alien.

In short, find another image.

Dag, the full version of Gigapixel is pretty good at upsampling, but you wouldn’t use it for a competition entry. You get a lot of model options with the full version, and they make a real difference. Diagonals will not show jaggies regardless, but details can start to look pretty crunchy. I’ve been seeing similar artefacts with webcam interviews on the TV news when they wheel out one of their talking-head ‘experts’. Skin too smooth, and wrinkles with way too much contrast making the image look nasty. I know you are not a fan, but it has its uses — just not for preparing best quality compo images.

Yes, well, some are probably more prone to artifacts than others. But there is always some and I’ve seen some horrible examples.

If I had to upsample, gun to my head, I’d still use traditional bicubic smoother, and then spend a considerable amount of time optimising sharpening and noise reduction - which Photoshop still does better than anything else. Maybe ACR super resolution in some areas, but even that has the occasional tendency to giveaway artifacts.

The bottom line is that it always, no exception, looks best at native resolution.

The thing that has surprised me most over the last year or so, is how incredibly easy it is to spot generative AI when you know what to look for, be it text, images or video. There is always an air of generic and non-specific sameness. In short, it’s dull and boring and uninteresting. I’m not buying.

Yea, @c.pfaffenbichler said it: 10 inches at 72 ppi is 720px. It's like saying you want 10 feet to fit inside a yard - not going to happen, unless you alter one of the three numbers. It sounds like the competition committee doesn't really know about how image dimensions works. If the end result is a print for showing, then I would keep the 10 inches. Otherwise, I would go with 2000 ppi at 72 and let the inche measurement fall where it may.

10inches at 72ppi are 720px.

If you need more then you need to upsample the image which you can do with Image > Image Size.

But you might get a more aesthetically pleasing result with Image > Generative Upscale, Filter > Neural Filters > Super Zoom, …
