Preparing your images for print

In this video tutorial, Karl talks to you about preparing your images for display print and runs you through various stages including screen calibration and preparation of your image in Photoshop.


  1. That makes sense. Thanks for pointing out the scientifics of the unsharp mask re changing relative contrast. That helps me understand what’s going on under the hood and will aid me with adjustments.

  2. I understand the first technique for adding ‘sharpness’ using the unsharp mask. But when you move on to adding more contrast, also using the unsharp mask tool, won’t those settings then overwrite the original unsharp mask setting that you used to sharpen the image? Or do you use two layers, one for sharpness and another for contrast? How does that work?

    1. Hi Nigel, no they don’t overwrite they simply add, even if I used the same settings you would notice it ‘sharpen’ slightly more. But and this is very very important, remember that sharpening isn’t sharpening, that is actually impossible as there are no extra pixels. All it is doing is changing relative contrast between adjoining pixels in key places to enhance the appearance of sharpening. On my second adjustment with my different settings I’m changing contrast in a different way and different areas of the image.
