Gadget & Tomkin,
Just a comment....
it's not a race or a competition, the aim should be to help, even if the pics are slightly better than the original most people appreciate the results.
People use different methods to get different results, after all it is only a hobby? and we're not all professionals at this type of work?.
Some people use filters & plugins and the pictures can be done fairly quickly, just the other day i had a go at using the healing brush in photoshop at a friends and you can get some quick results with it.
Others like the challenge to brush, burn & dodge going down to pixel level to blend, merge, shape and clone to get the results they think fit which can take some time to do.
At the end of the day if the person who posted the pic is happy, then everyone should be happy.
