I have a PDF target job containing a few hundred patches specified in the Lab colour space. I can import this into Photoshop specifying the 'Lab Color' mode and when I look at the Lab values of each patch they are exactly as the PDF says.
The problem comes when I choose to convert the image to a profile (any profile) because Photoshop appears to do no chromatic adaptation during the conversion. It is as though D50 is assumed, since that is the ICC standard. I can change X and Z values of the white point in the PDF to any numbers and the conversion is always unchanged. If the Y value is changed to any number other than 1, the Lab elements are not rendered in Photoshop.
Is there any way I persuade Photoshop to honour the chromatic adaptation implied by non-D50 white points? I am using CS2 on Windows.
I have a set of images in 32 bit .hdr format, which I would like to turn into 8 bit png files. Specifically, they are 6 sides of a cubemap, which join together seamlessly, and still need to do so after the conversion.
I've played around with the options in the HDR toning dialogue and have a setup I really like the look of, based around the 'local adaptation' method. The trouble is, if I apply those settings to each of the 6 images individually, they are no longer seamless (some have higher/lower contrast and brightness etc), presumably because these settings are 'relative to' the image being processed.
how can I apply the same kind of operations to each of these images (so they remain seamless), mimicking what the 'local adaptation' method is doing?
The specific settings I have changed in the dialogue are the edge glow radius and strength, the 'detail', and the colour vibrance and saturation.
I am learning Photoshop from an excellent book by Scott Kelby. He has a section which clearly explains the use of Chromatic sliders. All I have is a check box. How do I get to these sliders? I have CS5.
I just got started in digital photography and have some experience in PS from a class i took in school.
I used to shoot film exclusively and I LOVED my crappy little plastic lensed camera called a Holga which produced dreamy focus, tons of vignetting, and some Chromatic Abberations. I really want to reproduce the effects given by this camera with images I take with my DSLR.
I can figure out how to vignette and create soft focus effects but how can I create chromatic abberations such as this one?
I have found a billion ways to get rid of abberations but no way to create one. Are there any plugins, actions or filters I can download somewhere?
What can be done to reduce or alter chromatic luminance qualities in photographic subjects of people (skin tones) and liquids (beverages, water, ice, etc.)?
I've used Chrome Acute in Elements 7 with success, but I'm not sure that I can plug it into CS6, not accordingly to Chrome Acutes homepage, so what do i do?
chromatic aberration correction has changed since CS3. It's limited to ONE pixel correction, or what ? It seems i cant get strong cyan/red bands anymore, i used it as an artistic effect and i need it back. I'm not interested in manual workflow (moving manually RGB channels),
I am using bridge CS5 (version 4.0.5.11) and working in camera raw. In the lens corrections tab in the manual control I have lost my chromatic Aberration controll, this is to say, it has disappeared. I now see under the manual tab I now see the transform controlls, below that I see lens vignetting. The chromatic aberration conrolls have disappeared, where have they gone and can I get them back and how do I do that?
I am a commercial photographer and have use Lighroom since it was introduced. I just updated Photoshop to CS6 and found that the Chromatic Aberration corrections I apply to an image in Lightroom 4.2 are NOT following the image when I open the image in CS6 using Command-E to open the image from Lightroom. All other Lightroom corrections have been applied, only the Chromatic Aberration correction is missing. One other piece of information is that I convert all RAW files to DNG when I inport the RAW file into Lightroom. I had none of these issues when I was using Photoshop CS5.
I have recently been playing with removing CA from pictures. I have a particular RAW file picture of the inside of a church dome. I have made a number of Develop Module adjustments. There is purple and green fringing along the window frames and the columns by the windows, which I would like to remove.
I can remove most of this fringing by checking the Remove Chromatic Aberration box and then either use the dropper tool or just slide the Amount sliders a bit for both the Purple and the Green fringes. I do see a noticeable difference.
However, I have a problem Exporting the resultant file. Right before I check the Remove CA box, I can Export the RAW file as a JPEG, with, say, 80% quality, and leaving size/dimensions unchanged.
After I check the Remove CA box, however, when I try to Export the file, I get 1 of 2 results. One result, probably more common, is that it appears as if the file is being Exported; however, after a bit of time, I get an error message that says "Not Enough Memory." The second thing which can happen is that it appears as if a file is being Exported, but there is no disc activity, and, after it looks as if the Export completes, there is no file in the folder I specified. If I try Exporting again, leaving everything exactly the same, I get no message at all telling me that the file already exists, confirming that it had not been exported the first time.
I have tried greatly reducing JPEG quality (down to 40% I think), and I still cannot Export. I have tried lowering the dimensions down to 1920 pixels on the long side, and I have tried restricting the file size to about 5000K. Nothing so far has allowed me to Export this file.
Yet, if I go back in the history, right before I checked the Remove CA box, I can Export that file.....although the only way I can do that is to first exit Lightroom and then relaunch it.
My PC is about 4 years old; I have 4 GB of memory. Maybe I need more, but even by trying to greatly reduce the file size, I have these problems.
In the Develop Module under Lens Corrections, the CA option is no longer present. It was there in the previous RC. In the Sync Settings, it is a still a selectable option.
I must state that I am miffed that manual adjustment of C.A. has disappeared in LR4. This would have been easier to understand if some commonly used lenses that are not the latest release had profiles available. For example, I shoot the older version Nikkor Micro D 60mm and 105mm lenses for underwater photography. I built a preset to correct the C.A., which I now assume won't work. The automatic setting does not entirely remove it. Is there any way to deal with this aside from adding an extra step and editing CA in Photoshop (which doesn't do a great job of it, either)?
I work with GIMP 2.8.4 on Windows XP. In order to remove strong lateral chromatic aberrations I tried the CA plugin version 3x What I saw in the preview looked good, but when I pressed the OK button no result appeared. What is the reason? How to install this plugin on Suse Linux step by step.
I've just recently found that new chromatic aberration tools kills settings for old chromatic aberration tools. Lets say I have a PV2010 photo with adjusted sliders for chromatic aberration reduction and selected defringe "all edges".Now I'm importing this photo to LR 4.1. I'm not updating process version!
Photo is automatically updated by Lightroom to new CA controls (note it still PV2010 photo). Well, I must say the the results are superb - they are the same as I was achieving with manual sliders, but now with only one click. But the problem is - Lightroom says that metadata have been changed, and I am writing back changes to XMP.But now XMP contains settings for new CA tools, but settings for old CA tools are LOST.
So if I want to open this image in ACR 6.6, or send it to someone with older LR version I end up with completely resetted CA settings, because ACR 6.6 does not have new CA tools, and settings for old tools are killed by LR 4.1 - they are just removed from XMP. So I am loosing CA removal settings completely when opening image in earlier version of application. And I am NOT updating process version!
I am having a problem with LR 4.2 in correcting chromatic aberation. When I try to use the "defringe tool" I receive the following error message, "Cannot set the purple or green fringe color. Please sample a representative fringe color agian." However, I can see the sampled pixel in the pallette and read the RGB values.
I have a preset in Lightroom set to export photos with the long-edge at 900px in length. Whenever I use the resize feature, the photos that result have horrible noise and I don't know what to do about it. I can export the images at full size without any noise, then use Photoshop CS5 to resize the images and still have cleaner photos.
Here's an example.
The following export preset it set as such:
- Export as JPEG - Quality = 100% - DPI = 300 - Resize to 900px on long-edge
The first photo is exported via Lightroom 5 with the above settings, then directly uploaded to Imgur.
The second photo only has the Resize feature disabled in Lightroom. It was then resized to 900px on long-edge in Photoshop CS5 and the uploaded to Imgur.
The only difference between these two photos is which program was used to shrink them down to 900 x 600px.
Here is link to the referenced photos: [URL]
What do you think could be causing this? Since the only difference between the photos is which program resized them, all I can think is that it's an LR5 issue...
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.
when 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?
I use Photoshop Elements 11. I am trying to upload photos to a website and the browse only goes to Windows/Pictures. How do I navigate to photoshop to upload pictures there?
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.
when I try to save a tagra file with a alpha channel in photoshop 7 the box for the alpha channel is greyed out, with an warning sign next to it, and the line below stating "file must be saved as a copy with this selection" When I examine the saved file the alpha channel is not there!
Has anybody got any idea why?
My old version of photoshop 6, allows you to save alpha channels!
