Problem with Multiply Blend Mode

Greetings,
I'm a Photoshop beginner with Photoshop 7. I've got a big problem with the Multiply blend mode. When I use this mode (i.e. with tools and/or layers), it often creates blocks of thin lines randomly throughout my pictures. I've tried everything I can think of and can't prevent this from happening. I've looked online and haven't found anyone else discussing this problem, can I be the only one who has had it?

I've attached a pic which, shows the discolored blocks. The actual lines they're made up of don't show up very well, but they do really stand out and totally wreck the picture!! This only happens in the Multiply mode that I know of. Any advice would be greatly appreciated!

Re: Problem with Multiply Blend Mode

they could be jpeg artifacts but it's hard to tell with such a small file...post a hi-res version to flickr so we can have a better look...

Thanks for your response! I've never used Flickr before, so hope this works.

I think the last photo titled "Multiply blend mode lines" is probably the best close up of the problem.

Yes, they're from the same camera. I haven't tried photoshopping images from other sources.

I've also added a couple more examples on Flickr, which might show the actual lines better (same link in previous post). One was created as a result of using the gradient tool and another using the brush tool, again, in Multiply blend mode.

Should I try using an image from another source? I don't have another camera, so would have to download something off the internet.

Thanks again!

Unfortunately, I don't have access to any better sources. My only camera is a new Canon PowerShot SD800 IS, which should be alright for a point and shoot.
So I'm stuck?

Re: Problem with Multiply Blend Mode

Very odd problem you have there. Its certainly not related to Photoshop itself, I've never seen anything like this. It may something to do with your setup, I assume you are using a PC, or some strange issue related to screen resolution (check your color depth) which I seem to remember is located in a control panel "displays"

Re: Problem with Multiply Blend Mode

pixelzombie - thanks for the beautiful pic. I wasn't sure how to know if a photo downloaded from the internet was from a "good source" or not...

Unfortunately, the problem's still there. If you click the link below and look at a large version of the photo, you can see the lines in the grey area, which I created with the gradient tool in Multiply mode:

Markzebra, Yes, I have a pretty good HP with Windows Vista and a Samsung SyncMaster 900BW monitor. Both are less than a year old. The display settings are optimized according to Windows instructions in the control panel. As far as I know, I don't have any other problems...including with Photoshop, or even other blending modes! Are you sure it isn't related to Photoshop?

I guess this is pretty unusual because, as I said, I haven't seen anything at all about this type of problem online. It's very frustrating, especially since I'd like to use Multiply alot if I could.
