You don't necessarily have to change an entire way of working; local problems like the isles and the head can be fixed locally by simply using the burning-in tool set to 'highlights'. Run it over the offending area at maybe 3% - 5% and problem gone. I'm talking about web images - hell knows what it may look like in print, but that's the past for me. Frankly, almost nothing most people do is worth printing, and I very much include my own amateur work in that thought. Images, by and large, are nothing more than passing thoughts, and few such are worth recording in a coffee-table book of essays!
