Photoshop 6 Question

[Mike_W]

I am in graphics class at my community college. I have a graphics (Photoshop 6) project due in a couple weeks. My question is, I am not sure I am understanding correctly about what type images I can open and use within Photoshop for my project. I was told to use high resolution images of 220 to 240 ppi (not dpi).
I was also told that these images would only be available off a cd-rom or from a graphics, stock-photo outlet. I purchased a cd-rom set of different pics, jpeg, gif, vector art, etc. I noticed that most of the so called "high-quality" photos were in jpeg format, and I checked all the different sets at the store to see if their pics were in another format such as .eps or .psd. All seemed to be in jpeg.
Can a jpeg image be high resolution enough to use in Photoshop?
My project must contain multiple images, must have filter effects used, labeled layers, and a finished printable size of 71/2 by 10 inches.
I am confused as to the high resolution part. The finished product has to be saved in a .eps (encapsulated post script) format to save the information such as layers intact and not flattened.
Can I open and use a jpeg image in Photoshop and then save it in high resolution .eps?

There shouldn't be a reason why you can't.

Mike,

Usually when you alter a jpeg image with Photoshop and save it, will save to .psd

[Scum333]

yeh, just save it to psd format.

i have not seen one image bundle that comes in psd format. psd format is used to start a raw photoshop project and then you wittle it down to various formats for transport and presentation.

You can have big jpegs, but they are plenty smaller than other file types. Just take a look at the file size. If the files are a few Mb's, they should be sufficiently high res. Or you could scan a few files on maximum resolution and get real big files like 100mb. Those are always very helpful

hi mike
regarding your first Q: dpi=dot per inch and ppi=pixel per inch
in photoshop these means the same even there is some differences.
second Q : high quality means with higher reso. then any reso with higher than 200 and higher it is consider as high quakity.
third Q : all image files are kind of flatten image ( means carry only one layer) Except those files created by photoshop or other software . psd files are one of most important files because you have all layers seperately so you can work on each one of them.
btw dont forget there is relation between those high resolution and printing.
have fun with your photoshop.
here are some links that will help you alot....

Thanks. I am aware of the dpi and ppi resolution. I was asking about what type of images I could open within Photoshop and still have enough resolution to make good quality prints. My project specifies minimum ppi of 220-240. I had a hard time finding photos on the web with that much resolution. I found some on the NASA site, which was perfect because of the theme of my project.
I was confused as to whether I could even utilize jpeg images. I was thinking only .psd or .eps illustrator high res images would work. The jpeg's I found were great!

"I had a hard time finding photos on the web with that much resolution. "
the reason you can not find too many photos is that the page become too big for downloading which i am sure you know it, but there are some places that you could find them .
i dont remember their address but i'll check for you.
another solution is if you have a scanner and some high quality pictures just scan them and import them.( just a thought).

Web pages typically use 75dpi images for standard web appearance. It gives a good image and it takes up no space at all. If you want high res pics, go to a site that specializes in pictures. NASA is a good example. A photographer's site and any art photo site, archive, historical site etc.. would have real nice photos.

Just a few examples. I am sure there are piles of websites. You can even search for photos high res and come up with a lot.

Yeah. The NASA and FEMA sites had a lot of great high rez pics. Now, I am struggling to find a good high rez pic of a wall of fire (flames only). No luck so far.
I have a possible inside lead to design a public relations poster for the Fire Department.

What comes to mind is the scene in the matrix where the flames burst out on the wall and then the floor...whichever. You could get a DVD and pull a screen capture. That should be a very nice high res pic. You know what scene I mean?

I don't know if you could use the pic for a job...
