View 9 RepliesI am on OSX using Photoshop CS6.
For a couple months now I have experienced the "Building Histograms" dialog appearing on nearly every move or action; moving an object, adjusting a shape, zooming in & out, simply selecting an object.
The building of the histograms almost always takes up to 10+ seconds to complete.
I have followed other topics where there was no solid professional answer to the problem. The closest thing everyone was able to pin it on was the use of an extension or add-on. I have none of these.
In my opinion an update / fix should be applied for this. I won't be interested in further debugging or providing information. Simply stating that I am experiencing this for history sake.
In the histogram palette menu there are red, green and blue histograms to give the saturation of those colors, and a luminosity histogram to give the overall ( greyscale) brightness. There is also an RGB option, presumably to give a composite version of the red, green and blue saturation. In Levels, however we have the same thing, except there is no luminosity option, only RGB. But RGB in this case cannot be a composite of the three color channels, as we use it to adjust brightness and contrast; in other words it is presumably the same as Luminosity in the histogram palette. Despite this, when I do adjustments to an image the RGB histogram in Levels looks identical to the RGB histogram in the histogram palette. I'm using PS 3 Extended.

I am working in Photoshop CS5 on a MacPro with Snow Leopard, 10.6.4. I have a file that is a little over a gigabyte open. Every time I make any changes to the file (i.e. select a different layers, grab the text tool, etc.) a menu pops up with a progress bar and says it is building the histgrams.
This process happens with EVERY move. As you can imagine, this has slowed my productivity down to a crawl. Can I do anything to make it stop rebuilding the histograms at every step?
Photoshop creates several preview images (more smaller than the original) for displaying the effects and creating histograms. So, I think that if I choose the cache level as 1 in the preference window, Photoshop does not create any smaller preview and it always displays information according to the original file.
But, this is not the case, as far as I can see. I set my cache level to 1 and it still displays histogram for cache level 3. So, my question is ... what is the secret behind the cache level?
The histograms on the library panel and on the develop panel are not same for most of the images, there is a tiny difference between them. What is the reason for this difference?

I started to get this strange error with my Photoshop when making a new document in Photoshop and got the following error: "cannot initiate Photoshop because Photoshop cannot create any more windows".
I thought the easiest thing to do would be to reinstall (Photoshop needs reinstalling extremely often unfortunately), but now when I try and open the program it just give an alert beep and closes back up. Even though I rarely use ImageReady, I opened that up to check and it does the same behavior.
Can anyone tell me what color settings I need to set in photoshop in order to avoid this from happening? It only happens once in a while and I don't know what I've done to fix it or screw it up. What happens is that when I'm in photoshop and I do a "save for web" my document jumps to image ready and when viewing '2 up' for optimization purposes and comparison, I realize that the original view is actually duller in color and does not look like the original in photoshop. The blacks are definitely not as black.
View 1 Replies View Relatedwhen I got my first Macintosh IICX and all of my MacPaint clip art. I don't want to get rid of the clip art because since I'm still using a black ink printer and not upgrading to a color one, the clip art looks nice in newsletters and the like.
Up until this time I had been using SuperPaint which had the New Superbits editing plug-in to refine the pictures so they had the smoother and cleaner lines instead of looking jagged. With my new computer and printer, I'm also getting Photoshop CS packaged with Adobe Creative Suite Premium, which I have never used before. Since I have not received my order yet, I was wondering if anyone could tell me whether Photoshop has the capability of improving the older MacPaint clip art like SuperPaint did with the New SuperBits editing plug-in. Over the past two days, I have been trying like crazy to back-up my pictures with SuperPaint and then re-saving them with Graphic Converter. It's been so incredibly slow that I thought I would go ahead and ask you, the experts, if Photoshop can also improve the quality of my older MacPaint clip art or if I should continue to back-up my clip art like I have been doing.
I have just got back from the Elbow gig and pulled the images off the card. They load up in Bridge but don't have actual picture thumbnails. They are named correctly, ie: IMG_3483.CR2 but they won't open!? Error message says 'Could not complete your request because Photoshop does not recognise this type of file'
I could see them on the back of the camera.
mac users... i did a software update the other day and I noticed that there was an update for ACR. Could it have been something to do with that? And why can't I find ACR in my Applications?

View 3 Replies View Related of Adobe Photoshop v6.0.1 (quite old, I know, but it do all I want and on my old HW I did not plan/want to use any more recent version, because they are HUGE and with just a little preferences trick, I did not need to reinstall my PS - ever ), yet as Czech user, I need my software to type some special characters as well. These are looking like this:
[URL]...
Now the only problem is, that some of them PS just refuse to type. Seven small and seven caps are just wrong. See the line "for PS:"...
I battled the problem even by editing the fonts itsels, because that seems to work with Adobe Illustrator, yet this also cause the edited fonts to be useless in another programs. So I looked deeply and in the Adobe settings in directory Fonts / Reqrd are directory CMaps and perhaps editing the character map used will be better and usable solution? how to do it or even determine with file from the 96 files in the CMaps directory are right now used by Adobe Photoshop?
Everytime I open my CS6, it always show " Could not initialize Photoshop because the preferences file was invalid (it has been deleted)" I reinstalled it but it is still popping out.

Has anybody got any idea why?
My old version of photoshop 6, allows you to save alpha channels!
the soft edge feature of the eraser and the brush no longer work. I can go into the pallet and choose a soft edge eraser or brush, but it comes up hard edge. When I try to use the marquee box with a feather to get a soft edge, I again get a hard edge. I've used this technique a lot, so I think I'm doing the method properly. I have removed the preference files a number of times and have trashed the old Photoshop and reinstalled Photoshop 3 or 4 times,
View 2 Replies View RelatedI am working on someone elses computer and the Software settings are different. The old owner does not use this computer anymore. The swatches are set and I would like it to function how it usually does, etc. I mean, even the transparent swatch on the tool bar is not there anymore, so when I use the pen path tool, I get these white and black fills which makes it difficult for me to see the path I am meant to be following.
How do I reset Photoshop so that I can customise it the way I want it? Reinstalling the softwares is not an option.
I would like to reset Illustrator, Indesign, Dreamweaver, etc.
I'm having trouble with my zoom tool. If I have multiple Photoshop windows open, when I go to either zoom in or out of the top window... ALL the other windows mirror what's happening to the top window.

This means that I know exactly what I want on each page and I've done the whole page by adobe photoshop. However, most website host needs the file to be in html in order for it to appear on the web. Is there any way to change an adobe photoshop image into a html file without changing the layout or anything? Coz it was hard work designing the layout and inserting the content into adobe photoshop image.

These files are saved as TIFFs, and as part of my workflow, I have just about everything in Groups. She currently has Elements 10 on her system, but that absolutely does not permit access to the Groups and the components within. Because of her job duties, I cannot necessarily justify adding her to the CC account since she does not need PS, AI, ID, or any of the other applications as I do. However, I can easily justify upgrading her to Elements 12...provided it does what we need it to.

Whenever I am working in Photoshop, my blue looks purple, my red looks orange, but my green seems ok, however when I save it, the colour is different. I know it is not the gamma because that affects everything, not just how Photoshop looks (I'm pretty sure). If someone could help me and tell me how much of a loser I am and give me some simple solution, that would be great because it's a pain not being able to see what it is really going to look like without saving it and looking at that.

I made a graphic, hosted it on a site, and looked at it in a browser. For some reason, the colors in the image look darker than how it does in Photoshop.
What do I need to do to make them both look alike or maybe I should be asking, "How do I make Photoshop display the color it will show as in a browser?"
If it's any help, I'm using a working space of "Adobe RGB 1998." Is this correct for web design work?
