Desk top publishing

In just a few days I will participate in an exhibition so I've better get ready. Last week I spent quite a number of hours in the darkroom. Today, after selection of pictures, I started retouching them. However careful you are there are always dust dots to remove. And I am just a beginner in retouching images. It's far more easy in photoshop. But a well done copy from the darkroom gives me far more satisfaction.
