'Photoshop®' for Railway Photographers

I have spent some time wandering in the 'Photoshop' mist'. Whilst not considering myself an expert with Photoshop here are some hints and tips for the digitally challenged that I've picked up along the way. Since I use 'Adobe Photoshop version CS2' the suggestions made refer in the main to that software, other version may be slightly different. Software from other makers is likely to have similar features.
