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.

If you perform regular lightroom catalog backups, it is very likely that the backups of your catalog themselves are taking up space. I back up my catalog every time I exit LR, and currently the backups of just the catalog are taking up 16.7GB of space. You can simply delete the backups, or delete the oldest ones (each is stored in its own dated folder), to ...

Lightroom doesn't store a copy of your photo in its catalog. It stores the metadata and previews of your image. Essentially, it grabs the jpeg preview, shooting info etc, and creates its own higher resolution jpeg, but leaves the image file untouched. So, there really is no reason to remove photos from the catalog. What takes up room on the hard drive is the ...

Select your RAWs
Right click and choose export
Scroll down and in image format
Choose originals
Then you have exported your RAWs
For me DNG is useless as most of my clients don't want this format.

Well, if you dont want to reprogram dcraw, you can use it or a GUI version of it like my Image View Plus More 3 and set the parameters in the last steps such that they have no effect. Here I set toe = 0 gamma = 1, colourspace = raw, white balance = 1, 1, 1, and highlights = keep.
And the result:
Which can then be saved as 16bit png, or 16bit ppm or ...

I think this should be moved to Stackoverflow.
You can solve this problem. There is a clear indication that Libraw provides a good entry point. You can download additional demoisaicing methods here. So you could tap into that.
However, you probably have to do a bit of programming yourself, therefore this should be moved to StackOverflow.
Here is a ...

If I understand your question correctly, you are asking how you can use one existing tool to do certain steps to the RAW image, and then use another existing tool to apply other steps to the modified RAW image before it is converted to another format.
The short answer is, "You can't". This is because the nature of how a RAW image is demosaiced means many of ...

I'm not sure if what you mention is a known fact, but either way, you might want to read about color temperature and white balance.
Pay special attention to white balance shift, and do note that you can bracket your shots, efectively taking 3 pictures with different temperature at once.

The process that Canon uses in camera is proprietary and thus isn't going to be reproduced exactly by Lightroom. In general, when shooting RAW the idea is that the photographer wants to manually make adjustments, so looking like the in camera processing isn't really a goal of the software. The expectation is that the photographer knows what they want and ...

It looks like all the in-camera processing has done is brightened the image and given it a little contrast boost. This is about the most basic adjustment you can make in Lightroom or any other raw processor, so it should be no problem to replicate it and save it as a preset.
However, bear in mind that every shot is different (unless you're in well ...

Be careful using nx. Lightroom doesn't mind about the data added by nx, but some programs can't use the file after it's edited and saved by nx. Darktable can't use this file, and neither might some other future programs you might want to use.

In Lightroom you can store the development settings (Lightroom settings you have applied to an image) as a Preset. This Preset can then be shared with other Lightroom users together with your raw photo.
This YouTube movie shows you how to create presets: https://www.youtube.com/watch?v=QFuz0IwcyLs
Once created you can right-click on a preset and choose ...

You can export to a DNG file which is not a CR2 file, but is a digital negative (RAW file). It isn't the original Canon format, but should contain most of the same information, if not all of it (it also has an option to embed the original). I believe that the DNG will have the Lightroom alterations applied to it. You can export it using Export and ...

All changes are saved in xml "sidecar" file. Raw file is never touched.*
So you send him both files and then you can exchange only the small xml file that holds all changes.
[*] Unless you use DNG format and you set "do not use sidecar file, modify DNG file instead" option.

There is a useful discussion of this issue on the talk page for the Wikipedia entry for raw image format. To summarize, Wikipedia editors decided on "raw" because it is not an acronym and therefore they felt there was no logical basis for its capitalization. That said, they decided to note that it is often capitalized, acronym-style, in common usage. I ...

People wrote "RAW" to make the term stand out as a graphics file format. It isn't an acronym, and it isn't even a single format, but it does mean something slightly different from the English-language word raw by itself. Therefore, it's useful for it to have a convention where it's written differently.
A RAW file is a container format which includes ...

Adobe Lightroom (not so sure about Photoshop and rest) does not support command-line-scripting. You can easily write plug-ins and there are numerous resources to help you (SDK Guide, Lightroom SDK). But according to a thread on the Adobe-Forums, calling a script that executes a specific Lightroom action does not work from the command line.
A pity, really.

I have 2 D3200s and one of the first things I noticed was that at default "0" screen setting they are both way too bright. I'm a 40 yr vet to photography and it absolutely is a defect in the screen brightness. I own D3100, D5100, D700, D7000, D200 and others and have never had the problem with any other camera.

Well, you could open the raw file in a hex editor and read the 14bit values as 0x0000h-0x3FFFh if you like to have the "raw show you the 14bit data".
Alternatively you can map the entire range linearly to be viewed on your 8bit display, so there is no cuts in either end:
Now, that looks really boring. How abuot we apply 2.2 gamma curve to make use of ...

Virtually all computer, tablet, smart phone, etc. displays are limited to 24 bit color (8 bits per each of the Red, Green, and Blue channels). When an application displays an image file on such a screen, it has to either:
Choose an 8 bit zone of the original 12 to 14 bit data to display, with the brighter tones blown out and the darker tones pure black
or

The issue has nothing to do with bit-depth but with how much dynamic-range is shown.
RAW files record a certain number of bits per photosite. This is usually 12 or 14 bits. JPEG images offer a fixed bit-depth of 8-bits per color-component. What nearly all cameras due is create a JPEG preview for the RAW file and compute the histogram based on that preview. ...

Mostly because such a preview would be meaningless. When you go to do final output, you are virtually always outputting in 8 bit color and the display itself is 8 bit. Having a display that approximates final output is generally more useful that one that captures the whole amount of information stored. I suppose you can't tell immediately if highlights ...

If you are interested in this, I would suggest getting 'dcraw' which is a command line RAW converter. There is a Mac version for download from the site, the source code, and if you have HomeBrew installed, you can install it via 'brew install dcraw'.
The 'dcraw' program allows you to specify a variety of options including the Gamma and Exposure level ...

I think (I'm not sure though) there is no built-in command line tools for such task. Instead, you can use third party softwares. Allow me to introduce you to very nice ImageMagick.
It is a set of cross-platform command-line tools that allow you to do a lot. It has lots of tools and also many scripts based on it are available online. They have also a forum ...

Dynamic range is the difference between the darkest and brightest portion of an image. JPEGs have to represent each color with 8 bits of information where as raw can use more bits (thus more possible values).
There are two options for how the camera can resolve the difference in bit depth. Either it can represent a smaller variation for each value ...
