How can I take a company logo, blow it up, and make it clear to read in a powerpoint presentation?

I have Photoshop 7 but can't make it clear enough to read when blown up at a reasonable amount.

Find the original vector version of the logo.

Vector images can be resized without degradation, raster (bitmap) images can not.

A few things that everyone should know, especially if you are working with a designer on a project.

-It is always easier to shrink something than enlarge it (you can't make more pixels from nothing)

-Always start with a large image and shrink to fit your desired size (especially if you are going edit it first)

-For *most* print jobs the original image should be 300 dpi

-For logos, you should always have a vector (.eps) file of it if possible

Now, for your presentation, I'm guessing you are working with what you have. The best you can try is to go to Filter > Sharpen (good luck, it doesn't do that great of a job, and the larger you go from the original size the worse it will be).

Hope that helps, and sorry for the rant, but I get this all the time...

What's the company? Maybe I can help.

"What's our vector, Victor?"
"What's our clearance, Clarence?"

Sorry, it's Friday, and if I didn't type it, I'd have it in my head all afternoon (kinda like with a song) . . .

You forgot one,

"Roger, Roger"

"Over, Over."

Actually my wife is the one doing it. She is at work in a meeting and asked if I can try. I don't know if she obtained permission or whatever for the use of the logos. I am sure she did because it is being used for a big presentation with a big national bank.
The companies are NCR, Sun Microsystems, Bellsouth, and Hitachi.

Vector is that breakfast shit that tastes like rope...

Look for the logos here...

Thanks, that might help.

1. Mess around with the resampling methods - try bilinear, nearest neighbor, bicubic etc. Under "image->image size" you'll find those options.

2. Make sure your image is not limited to indexed colors. If you downloaded the pic from a website, there's a good chance it was saved to an indexed or web-based palette. Under "image," click "mode," and if it is not selected, click "RGB." Resampling indexed images is a bad idea, especially when using bicubic resampling (default) because the palette is limited to the colors in the image.

"Huh?"

Surely, you can't be serious.

"I am serious and don't call me surely"

"No, not a ba, a bomb."

"Excuse me miss, I speak jive."
