Taking notes on the Pink Beach
Originally uploaded by Mooganic.
Created using Topaz Labs, first clean then processed again using adjust to alter exposure and colour saturation. All worked on via Aperture 3 (not layers in Photoshop). Processing things through multiple passes with the Topaz Labs plugins can produce some very rich textures and effects.
If you use a layers based application like Photoshop or Pixelmator etc. you can isolate the impact of effects by employing a layer mask and brushing in or away one of the effects. This can be particularly useful if you wanted a pseudo HDR effect on a background but wished to keep a face looking more natural.
