Thanks Jeanie!
I don't keep track of my time, so it's hard to say how long I spend on something. I work sporadically I'm somewhat of a perfectionist, so I will spend how ever long it takes to get it done to my satisfation. Some days everything just clicks, and it's a quick job, other days, I could work from dawn to dusk. Obviously, I can't charge by the hour and so I have a fixed rate. I just don't think it's fair to charge someone for my crazy work style. (Each of the ones you mentioned would be $75).
PS: The beauty of working at home, for yourself.....I don't like being on a timeclock. For me, it's stifling and inhibiting. I don't measure my work by how long it takes, just the final result.
TECHNIQUE: I pretty much use the same old steps on everything (with the exception of photos like the porch photo). In most cases, 90% of my work is done with the clone tool. I also use the technique of blurring, adding a little noise, taking a SNAPSHOT, and cloning from that. More recently, I've been working with the CMYK channels to fix problems before I get started on the details.
I'll tell you what I DON"T use (and I see this mistake a lot). The SMUDGE tool. I highly recommend that people steer clear of that, it's just not natural and produces a "painted" appearance.
I also never use the DUST & SCRATCHES tool - I don't get enough control.
My big tip would be - work in very small, light steps.
I problably said more than you wanted, but sometimes I get carried away. I hope some of this was helpful!
