[thelist] "muddy" images

[Scott Harman]

Being a pure video type - I cannot see any reason why people would not
work in the highest quality imagery possible.
Storage is not expensive, and it's ridiculous to think in this day and
age that any company would not specifiy a minimum resolution of 4/8x
resultion at 300dpi as minimum working resolution.
For PAL output, all our renders are performed at 2880 x 2304 at 24bit
color (+ 8 bit alpha) then scaled down by a factor of 4 for broadcast,
or by a factor of 2 for print - and dynamic scaling for web output.
It's the only way to ensure quality throughout the production process.
One of our printers (now ex-) insisted that JPEG compression was
acceptable for print graphics, where instead we would provide TIFF and
TGA streams to ensure correctcolor spacing.

Just my slightly on-topic whine of the morning! :)

If I might add to Sharon's suggestion...

A statement like that might be very useful if graphics are an important
part of the site and the client knows a lot of AOL users are gonna be
the audience.  It will also go miles in quelling the AOL-centric
client's fears
- any client that I've had who's web world consists of AOL has had
trouble understanding the world outside of that environment.  Why AOL
has that option clicked ON by default is amazing in this day and age.


Carol also addresses the other question:

If a client is going to do the scanning I always ask for source images
sized at least 220 dpi, if not 300, reason being simply because the
larger screen image makes for more precise editing.  Then I bring them
down to 72 dpi when saving for the web (in Photoshop).

I've not seen any real reason to save to 96 dpi but I'm sure that's been
a subject of debate here before???
