Re: Help on scans---------
In Response To: Re: Help on scans--------- ()

Howdy,

I'm not familure with that program, but here are more generals that may help.

Look for words (in the help section?) like resize, resolution, resample or something that would make you think this is what they are refering to. This is where you would tell the graphics program that you want the image to be 72 dpi.

If there is a check box or option to resample the image (or something that makes you think this is what they are talking about) when you adjust the dpi, then make sure it is NOT checked. This will make the program keep the image the same size, but adjust the dpi. If the image changes size when you adjust the dpi, then it is being resampled.

Now, in the software that you use to actually scan the image into the computer with there may be a way to set it there. This is sometimes called a path. Meaning, the path from the scanner to where the image will end up. If the scanner knows the final image is going to be (email, screen, web) then it will scan it at 72 (or very close to it).

When using jpeg (jpg), which stands for Joint Photographic Experts Group you should be asked by your software how you want to save the picture. Using medium or 5 on a 1 to 10 scale is just fine for web.

Final notes, my images are gif (Graphic Interchange Format), which goes against what I told you in an earlier post about how cartoon like pics are best in gif and photo type pics are best in jpg (or another photo type compression scheme). This is because I want my chips to 'float' in mid air. This is accomplished by using transparency.

Transparency is best accomplished using PNG (Portable Network Graphics) compression as it can have 256 levels of transparency (opacity), however not all browsers support it. PNG also has gamma information saved directly in the file, so that each computer that looks at it will be able to make adjustments based on it's gamma. That solves the 'it looks this way on my home vs. work computer' (graphic cards aside).

The basic rule to remember is what will it be used for. Print? 72 dpi is going to look like a slabbed chip! 600 dpi is going to get you started, but if you use it for the web it will do murder to anyone who doesn't have high bandwith.

To give you an example, a 29mm X 29mm graphic at 72 dpi is 20k. A 29mm X 29mm (when printed) at 600 dpi is 1.34MB

Hope this helps and if not, just ask.
