Hi

I have bought the Canon Powershot G3, and I took some pictures with it. I think it is a great Camera.

But, when I went to post one of them on this website to ask a question about the algae in the pic, I had to resize it to get it under 256Kb.

What is the best file type and size to post here. The pic looks really grainy to me compared to the unresized one.

Thanks, BTW here is the resized pic

For color pics, you might want to go with a .jpg instead of .gif. .jpg compression is more efficient for color photos while .gif's are more efficient for black and whites. It also might have to do with your compression scheme from your software. The Gimp which is the photo editing software I use, automatically slightly compresses my pics which turns them slightly grainy. I have to adjust that before I can get a good clarity pic.

Typically, .jpg files are used for internet as they are compressed a bit more and make them smaller in kb. .gif files can also be used though.

As for size, to make viewing easy for everyone, you should probably be resizing images to a maximum of 600 pixels. Keeps the browser from expanding its edges and keeps people on dialup happy as well.

Lviewpro is a very quick and easy program if you need one to shrink the images. Photoshop is great as well (save for web option does work)...

Thanks guys

I am using Print shop photo pro express to edit the shots, although I did get Adobe Photoshop 5.0 bundled with the camera.

I will try some JPG's tonight, and I will remember the 600 thing. That always irritates me too.

Bryan

BTW I just love this camera

JPEG is a great standard for compressing photographic-like images.
GIF is perfect for web graphics that are NOT like photos: Where the image may have large areas of the same color. You only get 256 colors with GIFs, but you can really, really get great compression ratios with it if the colors are smooth (without gradients) and there are not too many edges.

Add an example, on the screen I am looking at while typing this message, the clownfish Reefs.org logo should be a JPEG, while the little smiley faces :)
should be GIFs.

Hope this is clear.
Basically, for photos from your camera, use JPEGs exclusively...

Regards.

If you've got photoshop, it probably has a function called "save for web" (at least my copy of photoshop elements 2.0 does. With that function it automatically compresses the photos down to a reasonable filesize without a great sacrifice in quality. Also, you can specify screen size as well. I usually make my photos 650p wide--that seems to make for a nice size photo that is large enough to see detail, yet small enough that most users don't have to scroll their screens to see the whole thing.

I second what John says. I think one of the best investments I made was getting the new Photoshop Elements. I've used several editors and it's by far the best in my opinion. Very user friendly and comes with a utility to adjust your monitor color as well. The "save as" function is great and allows you to adjust the quality of the pic, even showing the file size before you save it. It's so much better than what I've used in the past, that I've gone through hundreds of scanned photos and redone the touch-ups. Since a lot of my scans are from 20yo prints, the scratch removal tool is excellant.

Peace,

Chip

Cut-down, more beginner-friendly version of photoshop. Usually goes for around $60-$99 instead of the $700+ tag of PS 7.0. 8O :D

Every time you save a jpg file it gets compressed and therefore loses quality.

I always save pics that I want to keep to a tif first. This uncompresses the file. Now the file is at it's best possible quality.

If I want to post the file to the internet or send it via email, I save it to 640x480 at about 70%-80% quality. Now here is where I am careful. If after I save the pic, I think that I went to high or low on the quality, (maybe the picture looks distorted becuase I compressed it too much, or maybe the file size is still too big to be efficiently posted on the net or sent via email), I always revert back to the tif and save it again at a different setting until I am satisfied.


NEXT.....

If I take a great pic and want to share it with someone via email, I always tell them what the original size was of the image. This way, when they get the compressed jpg, they can resize it back to the original size as a tif file and get the uncompressed image at it's largest size.


Results may vary depending on the quality of the orginal picture.

The Canon G3 is a great camera. A good friend of mine here at the office has one. We were comparing pics between it and my Olympus C-5050Z and the Nikon 5700. The G3 had great picture quality considering it was 2MP less. The G3 images tended to have a lot more magenta in the pics though. Everything had a slight blue/purple haze to it. Easily corrected with software. Are you expreriencing anything like that?

No, the color's look pretty accurate.

Mine is the Powershot G3 and is 4 Megapixels

I am looking for a way to hook it up to my telescope though

Anyone ever done that?
