Happy Canada Day, everyone. In the absence of any actual photography (I have some digital stuff in the pipeline, but sadly, have not taken out the Rolleiflex in several weeks) here are some interesting links that may of interest to my readers (are you out there?)

“Popping” images with Unsharp Masking

Colour Digital,Photographica,Worth visiting — Jordan on April 30, 2009

Over at The Online Photographer (a site that has lately become regular reading for me) a recent post by Ctein linked back to an excellent summary of the benefits of using low-level, high-radius Unsharp Masking as a way to get images to “pop”. This is a technique that I use on almost every scanned image — for lack of a better description, it increases contrast “locally” without making the whole image look contrasty. Ctein explains how it works better than I ever could, though he does use different settings (I typically sharpen at 20% with a 20- or 30-pixel radius, while Ctein uses 8-15% over 60 pixels).

I remember feeling elated when I discovered this technique. It gives images just a bit of an edge without any hint of that nasty over-sharpened or posterized look. You can use it in pretty much any image-editing software that provides an Unsharp Mask tool. It’s simple and definitely worth trying.
