Sounds a bit iffy to me... A card, by itself, DOESN'T have a fixed L*a*b* colour - that's a product of the reflectivity of the card at different wavelengths and the intensity and wavelength distribution of the illumination. In the dark, L* will be 0. Light it with a coloured light and your a*b* will change. Light it with a "white" light with a different ...

This frequently comes up in photographic reproduction jobs where one is trying to closely approximate some other object such as a painting antique drawing. This cannot be done with typical photographs even when adjusting them to a specific, matching, LAB color. Regular photographs increase color saturation and tailor contrast, boosting the midranges and ...

The display corruption could be a consequence of using GPU acceleration in the ACR module. Not all cards are supported, so try toggling off the option. Also make sure that option is off in Photoshop.

The raw image is 12 (or maybe 14) bits, and JPG is 8 bits (less range). JPG does not handle changes of extreme range well. The JPG image already has white balance and color profile in it, likely our bad guessed try that has to be corrected first (which is the reason we are looking at it). Not even speaking of JPG artifacts, the Raw always is the ...

Anything you do in Camera Raw is non-destructive. It will save the changes in an XMP file so that adjustments are applied when you view the file and edit it. But you can manually undo them anytime you want. The easiest way is to simply delete the XMP file. Or you can open the raw file in ACR and undo the changes. For example, select the crop tool, then ...

When you are in Camera RAW, make whatever adjustments you like, then press the shift key. The open button changes to Open Object. This gives you a re-editable object -- i.e., you can dive back into Camera RAW if you like simply by double-clicking the smart object layer. All of that said, if you make any raster level adjustments in Photoshop -- say a ...

In Camera RAW 7.0 you can just click on the little arrows on the top right or top left of the histogram display. The one on the left turns on/off the shadow indicator(blues), the one on the right turns on/off the highlight indicator(reds). Alternatively you can use the keyboard "O" to toggle the highlight warning, and "U" to toggle the shadow warning. More ...

What you need to do when in Camera Raw, if you think you may want to make further ACR changes, is instead of clicking the Open button, first hold down Shift and the button will switch to "Open Object". Now click it and you will get a smart object layer. You can double click on that at any time and reopen ACR and make adjustments and keep anything you've ...

The principal difference is that some adjustments in Camera Raw are applied before demosaicing / conversion to destination colourspace & bitdepth. Such adjustments can't be replicated readily in Photoshop. Additionally the range and behaviour of adjustments is different between Camera Raw and Photoshop, some have migrated across (e.g. fill light) but ...

White balancing when implemented correctly (like in Lightroom) ensures that whites stay white under the new illuminant, essentially mimicking the chromatic adaption performed by the human visual system. When you white balance a photo in Lightroom you are effectively picking an illuminant / whitepoint colour temperature for your photo. The result of that ...

Don't worry that the D5100 isn't listed. The picture controls can be downloaded for use by the software (View NX2) or to be uploaded onto the camera. You're only interested in making them available for View NX2, so don't need to worry about the camera model. If you haven't selected another Picture Control setting in your D5100 menu, it will have defaulted ...

The basic problem with taking photos underwater is that the water absorbs quite a bit of light. It absorbs red more than it absorbs blue. As you can see in this wikipedia article on Electromagnetic Absorption by Water, there's about 100x more absorption of red/orange light (per metre of water) than blue/purple light. I'm not sure that simple white balance ...

Resize and then sharpen is the answer. It is commonly said that sharpening should be the last step. This make sense because you do not want to stretch the effects of sharpening. Sure you could do more complicated things but the lest steps are applied the less change there will be of seeing artifacts in the final image.

The limitations when working with JPEG image files, as compared to working with raw data, isn't so much in the application used (unless it is a poorly written application - which could be the case for either raw or jpeg processing). The limitations are self-imposed by choosing to edit a JPEG image instead of a raw file and by the way previously converting to ...

If you are referring to this EIP File Format – Enhanced Image Package, the format is specific to Capture One. Support by other programs is unlikely, and Adobe's list of supported file formats for Photoshop does not include it. If you don't have the original files from which the EIP file was created, you may be able to use a standard unzipping tool to ...

Come to the light side. We may not have cookies, but we have legitimate free software. The creators of Photoshop, as is their right, decided to keep the internals of the program proprietary and to charge money for access and use. But, other programmers have decided to take a different approach and created RAW-processing software like Darktable and ...

Any image that is not a native RAW format or DNG only provides the basic set of white balance options. This could be JPEG, as well as TIFF, PSD, or any other image format that Lightroom can load. The reason for this is that the full range of white balance and exposure adjustments are only really viable with RAW files to start with, and adjusting any one of ...

This is certainly something easily done in lightroom. If you import all 1200 photographs you can select all and then apply whatever development processes you want before exporting as jpg. My preferred route though would be to create a development preset and set that as the default before importing and then to create a filesystem publishing entry with ...

I sucessfully used NEF-to-JPG. It is freeware, and can convert from NEF to JPG or TIFF formats

You can convert your cr2 files to DNG files. DNG files are openable with anything. You can convert them using this tool http://www.adobe.com/support/downloads/product.jsp?product=106&platform=Windows

The support for the Canon 7D's RAW files was incorporated in Camera Raw 5.6 and the latest version of Camera Raw supported by Photoshop CS2 is 3.7 so there are no support for the .cr2 files created by the 7D in CS2. Unfortunately there is no way of opening these files in such an old version of Photoshop (unless there's a strange hack that I don't know of) ...

According to the Adobe help on camera raw: To toggle visibility of the mask overlay, use the Show Mask option, press Y, or position the pointer over the pin icon. To customize the color of the mask overlay, click the color swatch next to the Show Mask option. Then, choose a new color from the Color Picker.

You would have to upgrade Lightroom or Elements, as only the latest versions support the 6D. The Canon 6D requires Camera Raw 7.3, which is compatible with Lightroom 4.3 Photoshop CS6 According to Adobe, Photoshop Elements 11 only supports ACR 7.0-7.2. However, it appears the 7.3 update may be applied to PS Elements 11.

The Canon Rebel T3i is supported in ACR version 6.4.1 which, unfortunately, means Photoshop CS5 or better for you: http://www.adobe.com/support/downloads/detail.jsp?ftpID=5104 for some more detail. You may want to consider the upgrade to CS6 or, alternately, getting the latest Lightroom version which will allow you to export to Photoshop while handling the ...

You need a newer version of ACR, and for that a newer version of Photoshop. An alternative to buying a new edition of Photoshop could be to use raw therapee. If you edit your raw files with raw therapee, you can do further processing in photoshop cs4, if you like. Raw therapee: http://www.rawtherapee.com/

A camera profile may consist of several operators, including: A linear transform (a matrix) from the camera RAW color space to CIE XYZ color space (used to compute the conversion transform to ProPhoto RGB, which is the working color space of Lightroom). An HSV lookup table - Similar to the HSL function in Lightroom, but provides much more control on the ...

I would imagine the advice was given to crop in ACR vs PE because edits within ACR would be non-destrctive vs PE which would be editing a JPEG in a destructive manner. I don't use either tool directly but this would be my assumption. For example, once you crop and save in Photoshop Elements, the image is overwritten and the cropped portion of the image lost(...
