This may have been already discussed at length, but I still thought it worth giving people the benefit of my wisdom (or stupidity, you decide!!)
For some months now I have wondered why my photos are rejected for bad dark, bad quality, just bad......I have now identified one of the major contributing factors (other than me not being very good). Colour calibration between camera, monitor and editing software. I finally got round to Adobe gamma and adjusting the screen to match the output on my printer. This was motivated by a new camera (20D). Well guess what. All those photos rejected for bad dark were too dark.......the surprise. And the quality jaggies are now easier to see with the right balance of contrast and brightness......yet more surprise.
So two things -
1. to those who are beginning - calibrate your monitor, Camera (if you can) and software to show the right results - I went for Adobergb1998.
2. to the screeners and responders to my forum posts- thank you for putting up with my "what have I done wrong here" posts. Your patience and guidance is to be noted.
I'm off now to see if I can increase my acceptance ratio - might take a few years but at least rejections will be down to raw talent, and not miscalibration of tools!!
