Here are a collection of other photography sites I enjoy using (starting with a few friend and family plugs!). I’ll add to these over the next few weeks.
My Flickr site
Sites by my partner Kim: Kim Byrne Photography & Kim Byrne Landscapes (at the time of writing this, the former is about to move over to a new WordPress tyle and the latter is still in the process of being built)
The Luminous Landscape – a great resource for general photography advice. I also enjoyed their LR & Photoshop videos.
