How can a print be 350 dots per inch with a high resolution rgb and yet be 8x12?

Need to know how to do this in PS please.

Kind of urgent.

Thanks in advance.

Edit= the requirements are as follows.

All submitted art should be of reproduction quality. We accept color or black-and-white prints and transparencies (no negatives, please) and digital files on CDs with printouts. Digital files should be TIFFs or JPEGs, highresolution RGB, 350 dots per inch and approximately 8 x12 inches.

In the "Image Size" choice in the PS menu (Image, Image Size - I think) there are boxes where you can enter desired sizes, either in pixels or in inches. With the aspect ratio, you may have to do some cropping to get exactly 8x12. But that aside, the bottom-most box should say something like "DPI" or "Resolution", and that's the one you type 350 into.

I don't have PS in front of me, so sorry if my names aren't exact. I hope this helps - it's the only way I know of to alter the resolution.

12 x 350 = 4200 pixels on the long edge
8 x 350 = 2800 pixels on the short end

Just resize to 4200 x 2800 and print at 8 x 12.

Yeah, I have done all that already. This I do know.

BUT, two things.

When I crop a 8x12 I don't get the image that I am after. Too much crop.

Also, when I enter 350 dpi the image is way small imo, and when enlarged is really pixelated.

I don't get it.

What I would do is to crop to a 3:2 ratio, then set the DPI to 350 without resampling. Then change the size to 8x12 with resampling.

it does say approximately 8 x 12, you could probably crop to 11 x 14, 10 x 13, or 8 x 10 if that works better for you.

so I am looking at an image that is in RAW.

presently it is 2988 pixels wide by 2336 pixels high.

so if I just enter the 8x12 dimensions under doc size, then I don't get the 350 dpi.

if I enter the 350 dpi, i don't get the correct doc size.

If I take the 2988/12= 249 and 2336/8=292 OR 3988/8=373.5 and 2336/12=195.

How do I crop to a 3:2 ratio?

I am not getting this.

Please help me.

Maybe you should watch Ben's tutorial.

I dont have Photoshop, but I have PSP. I can do it like this:
1. Open resize page
2. Change resolution to 350 first
3. Change print size to whatever you want it. But, the aspect ratio will depend on your camera.

Your photo is approx 1.28:1. So ,the closest to 8x12 you can get is 12x9 or 13x10 without cropping.
