Technical Issues


If you are currently handling enlargement work, you are probably aware of the image cropping that may need to be performed when printing an image from a 35mm negative to an 8"x10" sheet of paper. The same thing occurs when an image is scanned in from a negative or print size which does not correspond proportionally (in aspect ratio) to the desired output size. In simple terms this means that unless a scanned print is 2" x 2 1/2", 4" x 5", etc., it cannot be printed in its entirety to 8x10 size. One or both sides of a 35mm negative image (in landscape mode) or the top and/or bottom (in portrait mode) will have to be cropped to fill an 8x10 sheet of paper. If the entire image area is important it can be printed fully but larger than normal borders will have to be present on the long side of the 8x10 paper, whether in portrait or landscape mode.

Listed below are the true original to output size ratios. We have limited the target output sizes to 5x7 and 8x10 for convenience but any output size up to 8x10 is possible.

The amount of image that would be cropped out to fill the target print dimensions is variable. We prefer to print the image in its entirety, leaving borders, unless the customer has decided otherwise. Please make sure that your customer clearly understands this issue, and indicate on the order form what portion of an image should be cropped if needed.
