Had a word
with David P about his talk on 25th February. He said, OK, at the end of the
day, all we are interested in is the big picture and how it looks. But
understanding how pixels actually work to build your picture, and what happens
when you apply editing tools, can give you a level of understanding that will
open doors in digital photography you never realised existed.
The talk
assumes you know nothing, so if you do know stuff, please bear with...
He will describe what a pixel is, what editing
does to it, how big they are or can be, and how to change their size to suit
your purpose. Includes when to and when not to Resample, and what Interpolation and
Pixelation mean. Also the difference between image resolution and image sharpness,
and that between ppi and dpi.
Finally, how
to sharpen your pictures.
You know you
want to know all this. Questions and polite interruptions welcome. No handouts,
but if anyone would like a copy of the presentation (PowerPoint) to revisit
later, just bring a memory stick along with you.
