For some unknown reason i get a slowdown when using RGB color mode, brushes, even 1px sized brushes trail behind the cursor and makes it rather slow and rather problematic to draw and paint.When i change to any of the other modes, greyscale, cmyk, etc; this slowdown doesn't occur at all which results in no slowdown.
Yesterday, painting with 1000px brushes in rgb mode didn't even give a noticeable slowdown which is very weird. So the issue has to have happend today.
When using the brush tool what is the difference between using the brush in color mode on a normal layer vs using the brush in normal mode on a color mode layer?
In the Printer Settings drop down menu both Color Mode and Print Mode are grayed-out. This just happened I cannot think of anything I've done differently.
I'm using OS 10.6.8 and the latest Epson drivers for the 3880. I have re-installed both PS and the Epson drivers. If I print from Acrobat Reader everything seems to work fine, this only is happening in Photoshop CS5.
I have a PSD file open and I added a new layer via the copy command. I have added a Layer Mask to the new layer and I'm trying to use the Brush Tool with black forground to cover part of the new layer. I'm following an online tutorial step by step, but when I try to use the Brush Tool I get "could not use color replacement tool because it only works in full color mode". The Image>Mode is set to RGB.
The project is a photo montage. It was 4-color, now must become 2 colors. So I've changed each of the original 4-color photos (jpg and eps) into separate psd files (as grayscale/duotone/montage-and assigned it One pantone color)
In a new psd "montage" file, I plan to place each photo on its own layer, adjust tints, transparency, etc, to create one new montage/flattened.I'm not sure which color mode is best when setting up this new file, CMYK or grayscale?
Once the PS doc is done, the job will be saved as a PDF for 2-color printing.I want to insure the 2 pantone colors separate properly at press.
I am running a Q6600 quad core with 4gb ram, Windows XP Pro 32bit. Video card is Nvidia 8600GT 512mb with latest driver 1.8250 & have latest update of CS4 11.0.1.CS4 works fine for me for 40 - 60 mins or so & then starts to slow down. It gets to the stage where any selection tool is unusable. As ann extreme example, today I had been working on an image, then went to do something else for an hour or so, but left cs4 running with the image open, came back & 1 click of the quick selection tool resulted in a progress bar that took around 30 seconds to complete. If I shutdown cs4 & restart its fine again for a while. So it seems like some sort of memory leak.I have noted also that the enable Open GL option is greyed out. I tried resetting CS4 preferrences, but still greyed out. I had previously tried the DisallowOpenGL Windows_on patch from adobe, but found it made no difference so ran the DisallowOpenGLWindows_Off patch.I cant honestly remember if the openGL option was always greyed out or notI know there are lots of CS4 slow threads around, but I hadnt come across a thread on my version of the problem, where cs4 works ok for a while & then slows down.
After eagarly installing the CS4 extended trial (on vista x64...) (and yes I should have seen it coming, as it does with every new release...) I was extremely dissapointed to find that, well, it doesn't really work.
It loads fine, images load, but as soon as I try and use a tool, zoom, scroll, paint, etc... I get a huge lag/slowdown. For example, rotating the canvas becomes slow and horribly jumpy, brushes lag a few seconds behind my cursor....
I have so far only heard from one other user who is experiencing a similar problem and I cannot understand it. My PC is surely up to standard (see sig links for details) and the only thing I can think of is that vista 64 is working its usual magic. My drivers are up to date and I've played around with the RAM and open GL settings in both ati catalyst and CS4 but have got nowhere.
I have installed Corel VideoStudio Pro X4 (32bit version) on my Win7 64Bit laptop.But when I easy playback, preview, 2 tracks with a Crossfade the preview slowdown. I remeber X3 on the same laptop works fine.

I've just starting experiencing a tremendous slow-down in the viewport (Nitrous, Quadro 4000) . . . and discovered that the trajectory being displayed in the object properties is causing it. When I turn it off, everything runs as expected.
I've been experiencing some slowdown on my PC when exporting files from LR4. No matter the size, or if it's .jpg or .TIFF... it always gives me some frezzes (mouse etc)

I am using Gimp for years now, and few days ago I have updated to latest 2.8 version. However, since the update (more like clean installation than update) to 2.8 I am experiencing extreme slowdown while moving image around with middle mouse button (wheel) or with the button on my tablet's pen. The image gets thorn apart a Gimp freezes for about 10-15 seconds. The thing is, this only happens with 2.8 version (never happened with 2.6) and only while I am using middle mouse button (wheel), or the button on my tablet's pen, for moving around. If I use "Navigate" cross at bottom right, I can move the picture without any tearing and slowdown/freeze.
Intermediate and advanced members probably know the following technique (beginning users, probably should better first start with learning the tools before trying this):
1) Switch an RGB-image to another color mode (CMYK, CMY, Lab, ...)
2) Copy the channels you find in the other mode and paste them back in the original RGB image as Alpha Channels
What's the purpose of this?
By gathering channels of the same picture in other color modes, it becomes easier to get the best channel for your needs (selecting, masking, etc ...)or just for plain experimentation with other color modes
Why don't people do this:
The hassle of switching to other color modes, the copying, the pasting, ...
So, I made an action for this which gathers all the channels from CMYK, CMY, HSB, HSL, Grayscale, Lab and puts all these channels as alpha channels fully automatic.
WARNING BEFORE USING !!!
1) You should have the HSBHSL fitler installed (which you'll find in the goodies folder of your Photoshop software)
2) You should start out in RGB mode
This action has only been tested in Photoshop CS and Windows XP,
I draw comics digitally in Photoshop, working in Gray scale mode to reduce file size (I work very high-res). Is it possible to make Photoshop display certain layers in color, without switching to either CMYK or RGB mode?
I have two images on two layers, the one which is on the top has a blending mode set to it (hard light for example) and opacity at about 70%.
What I would like to do, is to save that image (which is on the top) so, that every time I combine those two images, I would get the same result. (By combining I mean applying those images on top of each other outside of photoshop.)
The opacity is not a problem - I can save the image as 32 bit bmp (8 bit alpha channel right?)
I need to create a document, which i want to print, in CMYK mode, but this is not possible on Photoshop elements 5. Apparently Photoshop doesn't support CMYK. Some of my colleagues are graphic designer who also work with Photoshop and they say, that CMYK is always available... I don't understand why it's not available on my software. Do i need to change the setting or something?
I changed the mode of a RGB image to HSB color model then copy and paste hue channel as a layer to the original RGB image ...After changing the blend mode of the hue layer to the hue blend mode..I can't see my original RGB image.
I have a layer with some blurred spots. I want them to glow. I have a colored background (light brown). For some reason, when I set my layer to Color Dodge it does nothing.
But when I make a group and set it to Color Dodge, then put my layer inside that, it glows like freakin crazy. Can anyone explain why this is? Should it work both ways? Is there some magic to groups?
I am reading a tutorial about the background eraser, and in this tutorial, on the screenshots, the erased parts are in red. It is the same red than the default one for the mask mode.
Is there a mode to see the mask color instead of what there is beneath the layer ?
Note : Maybe the tutorial author put a red layer beneath the current layer...
I wanted to create an action to determine if the color mode of an image is Lab, and if so, convert it to RGB. But there’s no conditional action test for Lab color mode. The list of conditions that can be tested includes RGB, grayscale, and a couple of other color modes, but not Lab, Can I get it done with scripting?
My PS don't want to understand me! Every time i close brush panel, save document and every time after starting PS i see this panel. In preference i try picking "Remember Panel Location", but it's not working. And this software don,t save last color mode, i start PS with grayscale mode.
I'm doing some painting with a lot of layers set to different blend modes. I find that every time I want to paint on one of these layers, I have to go to that layer, set the opacity back to 100, change the blend mode back to "normal" sample the color, then change everything back and continue painting. I realize I can save a swatch for the color, but it can get confusing when you're using subtle color differences on multiple layers. It seems like there should be a modifier key to the tool that samples the layers "true" color discarding opacity and blend mode.
