Thanks Peter but all I know is that if I go into manual I have my focus on auto.My depth of field is set at f5.9. I set my white balance manually using grey card whereas most people will have there's on auto and I keep my speed at 1/25th of a second. I also use a tripod and keep my distance to around 12 - 15 ins from the pen. My focal length I keep at 24mm.
I fiddle around with the f no's and the speed to see if I can make it better but I haven't succeeded yet.
White balance is a subject that you will be able to explain better than me Peter that I am certain of!!!!
As regarding Photoshop Paul told me to go into light levels and adjust to the histogram rather than auto and the same with sharpness !!
I am playing around with most of this stuff and reading books on it to try and learn a bit more as it is a fascinating subject and as Brian once said to me that quality photographs of pens goes hand in hand with making them or words to that effect!!!
I am reading this thread with great interest as the more that I can glean the better !!!!
