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 upgraded to LR4 from LR3. After opening LR4 I realized that the Develop/Basic menu sliders are identical to LR3, i.e., Exposure, Recovery, Fill Light, Blacks, Contrast, Clarity, Vibrance and Saturation.
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 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.
why there are scrubby sliders as well as the regular controls in Photoshop and other Adobe products. Obviously I must be missing something; but to my eye, this appears to be feature redundancy.
I edit color in LAB mode. In CS3 I would use the eyedropper tool to select a neutral point and then a levels layer to adjust the color while I was watching the LAB sliders in the color panel. Quick and easy.
Now the problem. In CS4 the color panel changes to greyscale when the levels layer is highlighted. How do I make the LAB sliders sticky? If I edit the color with simply a levels adjustment (not layer) it still works the old way I am used to. I toggled the dynamic slider preference to no avail and I can't find anything else I can change.
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...
iMac, OS 10.8.5 Photoshop CS 6. I have activated the Graphics Display Unit (or whatever it is called) and, with an image in Photoshop and its Layer selected, I do Filters > Render > Lighting Effects. I get the panel on the right called Properties and under it some sliders for Color, Hotspot, etc.
Burt moving the sliders makes no change to the image. Tutorials say that I should get a white elliptical shape with white blobs which should allow me to alter the lighting effects, ("Lighting Controls"?) but nothing appears. The tutorials show a "Menu Bar" should appear just under the three coloured blobs at the top left of the main window. That "Menu Bar" shows, from left to right, something like: a light bulb; Presets-Custom; Lights and three tiny blobs; some thing else; and at the right end, a check; Preview; Cancel; and OK in blue.
I think that "Menu Bar" with Preview checked must appear before I can use the lighting controls on the image.How the heck do I get to see a preview so that I can see and use the lighting controls?
In CS3 after clicking onto the slider "triangle" I can then adjust it with the mouse wheel. I don't appear to be able to do this in CS6. Can this be remedied?
What happened to the hand drag sliders in CS6? You know when you would create an adjustment layer and then you could hover below the sliders and just start dragging either way? And you could option+double click and reset the value to 0. Is this functionality still in CS6?
When dragging various sliders in Photoshop CS5, very often these sliders get "stuck" and move with the mouse even though you have released the mouse. Say you are dragging a slider to set the brush opacity to 50%. When you have set it to 50%, you release the mouse and move it away from the slider, only to find that the opacity still increases or decreases as you move your mouse. You have to click again to fix this, but then of course you have to go back and do it again.
Below is a small illustration (I can't take a screenshot of my mouse) of an example of when this happens:
This happens to me around once every 5 times I use a slider, i.e. extremely often. As you can imagine, it's very annoying and frustrating.I use a Wacom Bamboo Fun tablet, and I never use Photoshop without it so I cannot confirm whether this bug happens with a mouse or just the tablet.It doesn't just happen like on the above illustration, but also with any slider such as those in Adjustment Layers and Filters.The bug does not happen when using tools on the canvas. So the Brush tool, and every other tool, works fine and never gets "stuck".I have the latest version of Photoshop CS5.This is a bug that has always been in CS5 since the first version, and it has not been in previous versions of Photoshop.
Late 2008 15" MacBook Pro OS X Snow Leopard 10.6.7 (but the problem has existed way before 10.6.7) Photoshop CS5 version 12.0.2
I've seen color gradations in the tint sliders (which makes selecting exactly what color hue you're shooting for easier). Is this a feature only in CS3 and above (just like the histogram display in the curves palette)?
