[R-390] BIT Images I Used

[barry williams]

Okay, I think I know what you are meaning. Just so it doesn't seem like 
nit picking here, I was a graphics design major and illustrator, and 
have worked with those formats since the 80's. I know what I"m talking 
about.

I think what you mean is that you are converting your images to a 
background template, and then you redraw over the top of that, right? 
This would produce the object oriented TIFF files that you save in 
Elements.

Photoshop Elements is a stripped down program that was initially bundled 
free with scanners, so that explains the limited modes you have. The 
full Photoshop file format is a compact file that contains a lot of 
information including layers and other illustration options not 
available to PE. The same goes for Adobe Illustrator. The ideal method, 
if you have the software, is to always save in the Photoshop format. 
This saves everything and gives you all options. Then, save out to 
whatever you need for printing and use that just for the print job.

I think some of the confusion is that you are calling a bit mapped image 
a bit image. Bit images are bit mapped to screen pixels. Thus, the fixed 
and poor resolution like we had to put up with in the early 80's. It's 
okay most of the time as a background to trace over. I've done that 
often. TIFFs are not bit mapped files. They can import and save bit maps 
as-is, but they won't up convert them to the higher resolutions that 
true TIFFs produce.
