Photoshop question-#1?

Can anyone explain the differences in saving formats in Photoshop? What I mean is, I have been generally saving images/artwork in JPEG but recently discovered that this is not necessarily always the best way to save an image for different applications. (For example, I created a logo for a friend's business, saved it in JPEG, and then was told by my friend's printing company that BITMAP or TIFF is a better format to use for printing business cards as, these formats preserve the clarity of the image better. I had sent him the completed image as a large-sized file but, when he attempted to shrink it to a smaller size, the text I had included with the logo was not as crisp/sharp.)

I would really like to understand about different formats and which ones are better for different purposes. Please explain in simplest terms please as, I am still learning everything in general.

I don't know too much about the different formats. I save everything as BMP's, PNG's and PSD's. When you save it as a PSD, you can go back and edit it easily whenever you want.

Here's some more information on image formats that you might find helpful: http://en.wikipedia.org/wiki/Graphics_fi...

No offense, however I am amazed...you have no knowledge of file formats and you are making logos???

and Business cards? Business cards need to be saved in tiff format at 300 dpi. They also need to be designed to allow for bleed.

To save an image on a transparent background you need to use gif or png formats.

most files for the web can be saved as jpeg.

72 dpi is the norm for web graphics.
