Re: Resizing images for the web -Digest Number 49
- Hi everyone,
For photo manipulation software, I like Adobe
Photoshop the best, but it is the most expensive. In
the past I have had access via my employers (graphic
design, mulitmedia producer or university).
With Adobe PS there is great flexibility for altering
an image -- scan in a photo and fix what life didn't:
remove your boyfriend's zit from his otherwise lovely
face, compensate for an under/overexposure or a
hotspot, even shift color palettes and contrast (much
as you can with all the other programs, though with
lesser control I think).
The best feature is the one Dafne probably wants to
know the most about -- not so much the IMAGE size but
the FILE size; the combination of both will help
images load quickly on slow computers/connections.
First: manipulate your image at the highest
resolution. With each major change, save a different
version(i.e., Matt1.psd, Matt2.psd, etc) -- don't
overwrite (it's very hard to go back and get that
highlight 'just so', etc.). Notice these are not
image files yet, still Photoshop docs.
When you finally have the version you like and want to
put it on the web -- Photoshop lets you chose a format
(stick with .gif or .jpg - though .gifs load faster --
I prefer .jpg). (e.g., Matt.jpg)
In .jpg, you have the option to "save for the web" at
various degrees of resolution (best, okay, etc.).
Again, save this version differently (Matt4web.jpg);
you may not be happy with the loss of quality on the
first go and will have to make adjustments by
reopening the 'good version'(e.g., Matt.jpg) and
trying again at a higher resolution. (I've also cut
the size of an image but kept the resolution higher as
a compromise to the reverse).
Best example: Do you know how large the file of your
pic is on the Webheads Yahoo Groups page is? Mine is
a faculty photo and 92K -- larger than it should be --
I don't have any image manipulation software at the
moment. Though the image is tiny -- but the file size
This same file is approx. four times larger on my
homepage and takes that much more time to load on the
screen. At the smaller image size, no one will notice
the difference in file size but -- on a slower
computer -- the larger image could load up annoyingly
slow (my apologies - 2001-02 has been rough and rapid;
web has been the last thing on my mind).
I hope this helps (and doesn't confuse-- I'm getting
confused just reading it over!).
all the best,
