I attended this exhibit last year at the ROM, and it is well worth it. Over 100 photographers' are represented, and I think I spent about three hours going through it. (two or three times) The exhibit starts on November 21st.
A great way to make local adjustments to an image, using luminosity masks. Tony Kuyper has developed masks, in three combinations, lights, darks, and zones. He also has a panel for quick access to adjustments in Photoshop. The masks leave no outline, so it is great for LCE (Local Contrast Enhancements). The whole package is 40 USD, and his site includes a lot of tutorials. Pretty easy to use, and it gives you very good control over certain areas in an image that you choose.
A before and after comparison.
In this image I knew I had to lighten the lightest lights, and the darkest darks for print. The first image is before the luminosity mask, the second after.
