To be honest, the colour images haven’t had much done to them. Maybe a slight tweak to contrast and saturation and some noise reduction (to remove the noise that high ISO creates in colour images). All this is done in seconds in Lightroom.
The blue toned and sepia toned images are simple actions in Lightroom. My favourite though, is the ‘cold tone’ effect, where warm colours (reds and oranges etc) are desaturated and the cold colours (blues and greens) are slightly boosted. For some reason this effect seems to work really well with some concert photos (although certainly not all of them).
I must admit I don’t have any great plan for post processing – Lightroom allows you to view what different effects (actions) will look like before you actually apply them, so I just play and choose an action that compliments the image I’m working with. Once loaded I would expect to spend no more than 10-15 seconds on each image for post processing.
Also, I don’t use RAW, especially when I only have a few minutes to cram all my shots in. They fill up the camera buffer too quickly, and it’s a pain to work with afterwards. I know it can lead to more detail captured in the shots, and if I was looking to get maybe 10 shots from a concert that I’d spend ages processing afterwards then I’d consider it. However, my particular style is about trying to capture the atmosphere of a concert over a lot of photos, not looking for technical perfection in a single shot. It doesn’t worry me if it’s slightly underexposed or overexposed or the white balance is off (all things that could be fixed with RAW) as long as it evokes the right impression of what it was like to be at the live show.
Yike I’m starting to ramble now. I must learn to say what I mean in fewer words.
