What picture dimensions to people prefer for posting here?

You should suit yourself on picture format as everyone has a different
shaped monitor these days so whatever you choose will not be perfect for
all. Most picture viewing software is made to accommodate these
variations anyway, we are used to different shapes and sizes.

I've experimented with IrfanView and Digital Photo Professional.

I prefer Photoshop and use CS3 [well, about 1% of it].

First, there's the size in pixels.....................

I started with 800x600 in the days of small monitors then 1064x768 as
the monitors got bigger and more folks changed their screen resolution.
Now, I lean towards 1600x900 as it suits my screen here but if you've
got a 2 1/4" square print from the 1960s you do whatever you can, we
still wanna see it!


My originals come from an EOS 350D. It was the bee's knees when I bought
it 6 years ago, but it's practically Stone Age technology now. Original
file sizes vary from about 2.5kb to around the 4kb mark. 8 megapixels.

Your 350D is still a great camera. More megapixels does not always give
a 'better' photo. Buy better lenses first, that will show the greatest
improvement in your pics for the money. It looks like you meant MB
[megabyte] not kb [kilobit] for your image size (4kb is very small).

Thanks for the comments.

It's not that the 350D isn't any good, it's just that newer models have
better facilities. I'd been looking at the 60D just out of interest, and
a few days later discovered my nephew had one, so played with it a bit
at a family wedding. It's more convenient as far as the screen and the
settings display go, and a faster fps speed. As you say, the megapixel
count isn't important.

Better photos depend a lot on who's pushing the button. I've known
people with much fancier cameras than I've had in the past whose efforts
were consistently poor. My failures OTOH are due to the weather, people
getting their heads in the way, pilots flying at the wrong speed and the
phases of the tides and moon.

I did indeed mean MB. Win Exp was showing n,nnn KB as the file size and
I was thinking in terms of nnn KB for posted pics. Managed to confuse
myself.

Lenses I use are the Canon standard EFS 18-55 1:3.5-5.6 for when I need
a wider angle, EF 28-105 1:3.5-4.5 USM, and Sigma 50-500 1:4-6.3 APO.
The Sigma isn't the sharpest thing around, but it's acceptable,
especially if you can't afford better. I bought it second-hand for just
over half the normal price. Haven't tried printing bigger than A4 yet,
but I might one of these days.

Then there's the scanning resolution.

Sorry, I never scan prints so I can't say anything other than I would
assume, it is best to scan at max resolution and then reduce your file
size with software if required. And on file size - I have seen some
great shots posted here at less than 100KB. It depends on what you start
with.


I meant the resolution when resizing. Should have made myself clearer.


Time to get cracking with the blower brush and fetch the big Lowepro
from the loft.
