size required for panoramic prints.

I would like to have some pano prints made. Paper size will be 20 x 16. I would like to combine 2 pics on the print so as to give me 2 off 20 x 8 prints when guillotined. I am unsure as to what size to save both pictures to prior to submission. I have never done this before. Any help gratefully received. Am using my K10d and Jpeg and 18-55mm

I make up panos using Panorama Factory and then will attempt to place them into PS7.(god help me!) but am unsure of dimensions

CORRECTION TO MY EARLIER POST

Paper size will be 18 x 12 giving 2 prints of 18 X 6. Everything else is correct. I get dafter every day

In Photoshop you could create a 18 x 12 image comprising two 18 x 6 pictures.

John,

Not to put too fine a point on it............How????????

First, prepare your two images and crop then to the size you want. 18 x 6 at a resolution of 300ppi. (This is done in Image>Image Size)

The create a "piece of paper" to put them on. This is created by going File>New and then defining the size of your paper (18 x 12 at 300ppi)

Now drag and drop your two images onto the paper using the Move tool. Make sure they are lined up properly. Then Flatten the image as at this point you will have three layers (the background, Image 1 and Image 2).

Save As a TIFF.

Easier to show you than describe it, but I hope that helps. If you are in doubt about any part of that, just ask.

Thanks John,

I think I follow your instructions. Should I save as a Tiff if the processor requires Jpeg?

Thanks again

No, save as a JPEG if that is what is required.

What you could do is save your original as an uncompressed TIFF and then save under another file name the JPEG version for the processor. Best of both worlds then.

Do all your editing in psd, tiff or a similar format and only make the finished product JPEG.

Thanks for the assistance gentlemen. Greatly appreciated.
