Thanks Peter H, the subjects are usually breathtaking, as is getting to them! Not sure I'm getting that across as much as I would like though.
Adams certainly gets across what it 'feels' like to be there and this is what I hope to be able to do in time. Showing what something looks like is taking a good photo, showing what it feels like is very challenging and I guess thats why I like taking photos and being creative in the attempt.
If I was trying to show what something looks like then I would accept it as criticism for enhancing or modifying but I'm trying to do something different so the 'enhancing' is as much a part of it as taking the picture in the first place. But at the end of the day I dont do an awful lot of modifying in photoshop, I dont add anything, like skies from another picture, and I try not to remove anything unless its a strong distraction. I do try and add mood by tinkering with the exposure (before taking the picture), contrast curve and correcting any colour imbalance caused by the camera. The only filters I use are a polariser (very occasionally) and a ND grad grey to try and keep some detail in the sky without changing its colour. The Nikon D70 I use has a superb metering and flash system which helps enormously.
I do vary my style but not really for the sake of variety, it depends on the place and the picture. Some look better in B&W and some with deep colours, I just try to make a picture that translates what I saw and felt in a particular place so I think it can take a different interpretation from someone who wasn't there at that time and place.
