Hi guys!

When I very first started my Photoshop program for the FIRST time EVER, i got a pop up window message stating that I should set the primary scratch volumes on Photoshop or something.

I have noticed that with all the people I know they have not had the following problem which I believe is related to the above issue;

when creating an image, I have it perfectly how I want it. This pertains to hex colours, positioning etc. I then click on save for web in the drop down ‘file’ menu. Upon being prompted with a ‘preview box’ containing the graphic I had just created and been proud of, I realize the once exuberant tones of #CBE007 i once had have turnedf more into a more watered down ‘green’. On many other occasions, I have created an image with a nice, ‘watery’ blue, only to find my preview box contains the same graphic with a more illumious tone!

The program in itself is fine, but if anybody can please help me with this issue that is highly annoying, I would be eternally grateful.

Thank you very much in advance,

Charles Carter, 15.

Version: Adobe Photoshop 7

P.S I have been told that I need to set compression and i have experimented with all types of image saving such as .gif .jpeg and .bmp etc so that is also out of the question. Thanks again 😉

Scratch volumes and compression and color change are 3 different issues.

Scratch volume warning and set up:

Happy now? Or does that look like too much reading?

Chaz,

The message you received asked you where to set your scratch volume, and to prioritize it. This is in no way a problem, nor is it related to your other problem.

Photoshop uses a scratch disk – temporary disk space that it alone can use. It is temporary in that each time you close Photoshop, provided PS closes normally, it is deleted – kind of like a Word temp file.

When you start PS for the first time, you have some choices for where this temp file can be located. Most pundits put it on a separate drive as the primary, and in the event that drive ever gets full, they will appoint another drive as secondary (or tertiary).

That’s all that is.

Upon being prompted with a ‘preview box’ containing the graphic I had just created and been proud of, I realize the once exuberant tones of #CBE007 i once had have turnedf more into a more watered down ‘green’.

This is an indication that you need to calibrate your monitor using Adobe Gamma in the control panel (classic setting).

Photoshop is a color managed application, the web is not. That means that there is a profile that matches your display with the colors in the image to produce the colors you want. It’s like a translation table.

When you save for Web, you strip all the color information from the image. Thus, you are stripping the "translation table" and you will see it’s preview in a non-color managed state.

Having a corretly calibrated monitor, usually in the sRGB space, will show little or no difference between your image in photoshop and save for web, depending on your SFW settings.

So in sum, calibrate your monitor. The best information for doing so comes from a 15 minute read at Ian Lyons’ site:

Peace,
Tony

Well Tony, Sir, what can I say.

I really appreciate the time out you took to write this message, and I am sure your recommendations will become of great use to me, as I am about to see.

Thanks Phosphor, for whatever you did lol 😛

I am very grateful to you, and I am sure this will be sorted soon.

Thank you very much,

Chaz 🙂

Depends on the font, Dave.

I’m using FF 1.0.4, with Trebuchet. That "y"s descender is bisected.

I’ll thank you not to presume that we will tailor our posting habits solely for your benefit. I suggest if you want to get along well here, you step back a wee bit and see how things are already running here, and tailor YOUR behavior to the established norms. Unless you seriouly want to upset the natives, that is. It’s your call.

Visit the forums using a web browser if you want the full experience. That way you can check in when you have the time. If you lose track of your message, simply bookmark it like you would any other link online.

If you’re going to subscribe to a forum or thread through a newsreader, you have to expect the traffic a place like this generates, and check your own reaction to the number of emails you receive.

This ain’t no kiddie board, son, where dust devils and tumbleweeds blow by between posts.

doodZ: this is a public forum (that’s also mirrored on usenet). not your inbox. unsubscribe then just come here and check your thread. otherwise you takes what you getZ.

It’s not spam. Spam has its own definition, and spiced ham is the other one.

Chaz, this is a user forum. If you choose to have it sent to your inbox by email you will have to endure messages that might not seem on-topic (there has been a major thrash in another topic about how PSCS2 handles underlining, for example). Spam is pretty well-understood to be commercial solicitations, not mere BS. It’s pretty hard to avoid BS in any forum thread.

The difference in color you are seeing is probably related to color profiles. If the image was created using the Adobe RGB profile, when you go into Save for Web it won’t look right. You should convert it to sRGB first. Then it should look the same in Save for Web and will look similar on others’ monitors when viewed over the web.
