Hello all, this is really just a settings question (I hope) I am making a logo to go in front of a film, so it will be very large when done, probably a 4K film. I am wondering if anyone knows the best settings for such a ting? Or if illustrator is better, and if so what would be the settings there? Thank you for your time!

Resolution doesn't apply here. That's a print parameter.

If it's a one-off, you can just design at the final pixel dimensions. In a 4K canvas, anything between 1000 to 2000 pixels or thereabout. The DCI 4K standard specifies 4096 × 2160 pixels.

Without knowing the final dimensions, it's probably best to design as vector in Illustrator, so that you can scale freely later.

Thank you, so it wouldn't matter if I left it at the default 75 that it seems to load?

Stick to 72dpi,

dpi by definition means Dots Per Inch, so 72 dots per inch of the image.

If you take a 72 dpi image and print it, because it's only displaying 72 dots per inch it will most likely print out very pixilated, for printing, I would use 300 dpi - maybe even higher depending on the canvas size.

but if you're just working digitally you should stick with 72 dpi

Yes, 72 is as good as anything else, if you have to put something in there.

But just so we're perfectly clear on this: If it's intended for screen viewing - which it is in this case - the ppi setting is moot and irrelevant. This is why Save For Web and Export just strip this piece of metadata out of the file entirely. It's redundant, not needed.

If, by chance, you change your mind and decide to print such a file, and it doesn't have a ppi setting, Photoshop will assign 72. This is just a default number, again, as good as anything else. You can change it arbitrarily without affecting the image data - it will just print larger or smaller with the same number of pixels.

The reason this is so, is that a computer display, or cinema projector, or TV screen, all have their own native resolution. There already is a pixel grid that the image pixels align to - you don't have to make one up. That's what the ppi figure is - a made-up, imaginary pixel grid.

You have to create the image at the correct target resolution or larger from the getgo. There is no magic beyond that. The most common broadcast 4k flavors are 3840 x 2160 or 4096 x 2160 pixels.

Thank you. What about the resolution and color mode?
