I have a color negative scan that is a 64MB TIFF file. I crop and edit it and it turns into about 54MB. Then I need it to be 1.75in x 2.25in and print in the middle of a 4×6 sheet, so I turn the canvas size to 4×6, leaving the smaller image in the middle of the canvas. When I do this, the file size turns into 260MB. That doesn’t make sense, nor can my camera store print a file that large. Help!

Bill,

An image 1.75" x 2.25" should be about 664Kbyte ONLY.

You need to re-size the image from Image>Image Size with re-sampling ON and a resolution of 240 ppi to 300 ppi.

You will probably need to apply some Unsharp masking following the re-sampling

Bill check the resolution… chances are it was scanned at a higher dpi than you actually need eg… 4000 or 2000 dpi… and that’s the size you’re working in…. so, when you increase the canvas to 6x4in it’s 6 x X dpi by 4 x Xdpi. Therefore… You need to reduce the dpi of the image….

The other possibility is that your image was scanned in 16 bits per channel colour and you haven’t reduced it to 8 bits per channel. In which case, reduce the bit depth to 8bits per channel.

Cheers…

I need to print this and give it to the camera store to print. The Yearbook staff will then take the print and use it for the yearbook. I don’t know what they’re doing with it, but probably scanning it. They won’t take a digital image. What resolution should I use for that?

either print the 1.75×2.25 image to a regular sheet and trim by hand, or set the paper size to 4×6 and print the 1.75×2.25 with image centered (print w/preview). your problem is you’re adding all that blank area to the image’s actual size and that’s causing the file size to grow accordingly.
