Re: My photo`s are pixelating

Thanks for getting back to me :)

My graphics card on my old computer isn`t as high as on my sony vio lap top
and when I zoom into my picture by less than 100% it pixlates, this doesnt
happen on lager pics (2592 x 1944, dpi=720) it happenson the smaller pics
(640x481 dpi=230 and there abouts)

I`m zooming into my pics because I paint (amonst other subjects) pet
portraits, mainly dogs , and people send me their favorite photos to work
from, I need to zoom into the photo to get the minute details for the
portrait, I can`t ask people to send me bigger photos because on many
occassions the pet has passed on and sadley no more photos can be taken.

I don`t need the photo to stay zoomed into as a perminant thing, only while
I need to work on it for the artwork.

There`s no pixelation to the picture at all until I start to zoom to about
40 or 50 percent at a guess.

Many thanks
Pauline

I hope I can find an answer to my problem :)

can anyone tell me why my photos pixelate when I zoom into them, they are
okay for a few zoom clicks, but then they begin to pixelate, the problem
seems to be the same on Photo shop, Picaso and my other programs, but its a
little bit better on Office Picture Manager (which I still have on a trial
basis) the same pictures were perfectly okay on my old computer and I could
zoom right into them without pixelation, my old computer is a far lower spec
than my Sony vio so I expected the photo facilities to be as good or better
on the Sony. The odd thing is that the photos look perfect when the screen
saver slide show enlarges them, no pixelation at all!

I`d really appreciate it if somone can help me withthis problem, I`m not
very computery :) so I don`t know where to start looking, I need to use the
photos for my artwork and its getting urgent :) Thank you so much X

Several things effect how much or if images show pixelation.

Is there a difference between your old computer and the current one's
graphic card resolution? If you're using a flat screen monitor it
should be set to it's native resolution. The higher the resolution the
sharper images will appear but they get smaller, meaning they take up
less space on the monitor screen. I suspect you're simply over
zooming. If the image is raster based, not vector based it will show
some pixelation if you zoom in far enough.

What happens when you print the image?

Just how much are you zooming in? The normal limit is to increase the
image no more than 150% max. Anything beyond that it is going to start
to breakup to the extend it's not acceptable.

Why are you zooming in? If just to work on the image and you return it
to it's actual size before you save it, not an issue. However if you
are attempting to increase the overall size of the image or crop to
take part of the image then make that the same size as the original
the increase no more than 150% "rule" applies.

If you must make the image larger, increase it several small steps,
first converting to some lossless file format. In order words if you
want to increase some image to 150% of it's original size, do it in
steps. The first would increase by 10%, save result, that end product
becomes the source of the next increase you increase by another 10%
and so on until you get it to the size you want. Photoshop excels at
this, more so than other applications.

Depending on file type any picture you over zoom in on unless it's a
high bitrate can start to get pixelated to varying degrees when you
view it on your monitor.

If you can upload a image to some public site where others can see it,
you might get more detailed answers.

Is the picture pixelated at all when viewed at 100% (no zooming)?
