Your coment: "The point is, if you have enough memory (and you know you should), then there's no reason to shoot at lower resolution and risk missing the opportunity to show off your work in a big way" adds to my confusion about digital photography. I mainly take fishing pictures for my website. To avoid long download times I try to get the picture files down to about 20K. I had great 35mm shots which scanned/compressed nicely to 20K. I can't decided what to do for digital settings to get the same results. thanks

    I would suggest saving an origional digital image master in the highest resolution and dpi possible. I usually import and save mine in photoshop elements. If you are printing on your own photo quality printer, I like to stay around 240 dpi as a guideline. On most 5 mega pixels cameras you will maintain at least this dpi even after cropping. Multiplying your height by width will give you the desired resolution guideline. (example 5 x 7 photo is 1500 by 2100 at a 300 dpi resolution. I upload some of my shots to for professional prints and have found the same guideline to be sufficient for lab quality prints.
    Here's a not for those of you who use the Fuji photo processing machine at Wal Mart. IT DOESN'T RECOGNIZE ANYTHING OVER 300 DPI. You are wasitng your time trying to print anything with any greater dpi than that. Hope this helps.

    if you use Macromedia Fireworks MX and go through this route File\Export there should be steps to save your image at web quality. Also, there is a function through this route to specify the file size which you want.
    If you use microsoft photo editor and go to save as, select .jpg then click on the "more" button and select the quality manually. 50-70% is good enough.

    Hi there,

    On some high-end digital cameras, you have the option of saving the picture in both resolutions: hi and email. The email-picture is the compressed version of that picture. If you don't have that option with your camera, then you'd have to use a picture eiting software to compress it manually. The best one is Adobe Photoshop, but there are many less expensive and easy-to-use software for the consumers out there.

    I understand the initial confusion. Here's the way I explain it in my workshops. Think of the "high resolution" shot that you originally recorded with your camera as your "digital negative." This "master" enables you too make a photo-quality print, if you choose, at the maximum size your camera allows (5x7 for 2 megapixel, 8x10 for 3 megapixel, etc).

    But, in this case, you want to use those same images for your website. So then you open your "master" in an image editor, such as Photoshop Elements, make a copy of it (Save As), then resample down that copy so it is a small, web-servable file.

    Your original image is safe and sound so you can always return to it for other uses.

    The thing to remember is to keep your master files at high resolution, then make copies of them.

    I hope this helps...
