I've had my first go at post-processing an image using Photoshop today, it took me about half an hour, will post 'before' and 'after' images! Before I had a go at lightening the image in Photoshop, as you can see the sky's exposed fine but the catedral is far too dark: This is my first real attempt at post-processing an image using Photoshop, I used the magnetic lasso tool to select the cathedral, altered the levels and slightly reduced the green in the colour levels dialog box, and this is the result. I also had to manually go round the edge of the cathedral as there were some white parts (sky that had been lightened as well) where the lasso tool had just caught some of the sky as well (I though it'd missed it!). Probably not perfect and the composition's a bit off (missed the tops of the two spires) but I'm quite pleased with my first attempt with Photoshop! I'm after some C & C, I know it's not perfect - there's still the odd white bit I think - any suggestions on how I could improve this process, and avoid those white parts that I had to manually remove using the clone stamp would be welcome! Could I have used layers or something to do this better?
