Picture Size

[bgrayky]

I need to resize some pictures to take to the printer. They told me the resolution needed to be at least 294 and they needed to be in jpeg format. I am using Adobe Photoshop 7.0 could some please tell me how to resize these to get the best images for 8x10, 5x7 and 4x6 prints. When I change to document size it goes to 10x7.5 then I can set the resolution. pixel dimension increases also when i change the resolution. Please help.

If the images are correctly proportioned you just need to go to Image... Size and uncheck Resample Image. Then change the Resolution to 300 pixels/inch and click OK.

Nothing will seem to change, but the DPI info inside the image will change.

Now click on File... Save As... and choose JPG. Save it at a Quality of 12 for maximum quality.



If the images need cropping, too, then this sounds like a great use for the Crop tool...

Select the Crop tool from the toolbar, then up top you'll get some options:

(This is from Photoshop CS - I think it's the same in PS 7 though.)

For Width and Height enter the size you want, whether 4x6 as shown or 8x10 or whatever. Make sure that you type "4in" and "6in" to make sure you get Inches. For the Resolution, enter 300 for 300 DPI.

Now draw the crop how you want it. The settings you choose will keep the correct aspect ratio. When you've selected the image how you want click on Image... Crop. PS will crop it, and then resize it to 300 DPI.

Now File... Save As... and choose JPG, selecting a Quality of 12 for maximum quality.

The aspect ration for 8x10 and 5x7 is different from the 2:3 that comes out of the camera. Unless you distort the image you must crop it to the desired aspect ratio. Two different crops for 10x8 and 5x7.

You can set the crop tool to give the required size and DPI and then drag the frame around to choose the best position. When you commit the crop the image will also be resized to take account of the chosen DPI.

You might check whether your print lab can do the upsizing for you. In which case you could just set DPI to 300 and crop to the required aspect ratio without resizing.
