Splitting an Image for Print Upload

I have a massive panorama to print. Is is 18000x2500 pixels and I want to do a large print of it.

The print service I use can only offer aspect ratio 2.5:1 prints, so I need to split it into 3 equal parts (the whole thing is aspect ratio 7.4:1 or so).

I found the slice tool in photoshop but I cannot work out how to save the slices other than "save for web" which insists on interpolating the resolution down and also complains of not having enough memory. My machine has 16G of ram and 3T of disk so I don't think that the error message is very helpful.

What I really want to do is save the slices at full resolution with any further processing. I have the image ready for printing already.

Any ideas appreciated.

why dont you get it printed somewhere else.

I think it would cost alot to get a one-off print done at that aspect ratio - how would they mail it for example?

This cannot be that hard to do in photoshop surely. I find it an incredibly frustrating piece of software when you try to learn a new section. I really is impenetrable.

The mailing could easily be done in a tube, that the easy part.

I'd certainly want it printed in one piece. I have been asked to rescue an old, faded pano made up of two seperate prints (pre digital/pre photoshop) and am intending to reshoot the image because it will be far easier all round.

My Epson R2880 will print 13" wide by about 10 feet, so depending on what size you are after, printing it should not present too much of a problem.

If you really must chop it up, it can be done very easily in Photoshop:

1. Make sure the image is open with rulers selected, mm will be better than inches as they are smaller.
2. Carefully crop the first selection making sure you crop EXACTLY on a particular measurement. Save the cropped image using a different name to the original.
3. Edit>Step backwards through the previous cropping/saving and the original will reappear, using the exact measurement (which you wrote down!), recrop a second time, using that measurement as the start of the second crop. Save that to yet another name.
4. Repeat step 3 as many times as required.

This will produce a series of images which if carefully trimmed after printing will reproduce the whole image, but you will always be able to see the joins.

ok thx.

as i suspected, the slice feature is half-assed and bolted on, like 90% of photoshop. what you can do with it is good but it is an organisational nightmare. i would hate to work for adobe, must be a managerial wasteland.

btw, is there no way to crop to an exact, typed-in pixel point?

Use the rectangular marqué tool (fixed size), then go Image > crop.

Slice used to be an ImageReady feature, not PS. It's meant for websites, not "regular" images.
