As you say, white balance is a subjective game. The only way to do this in anyway objectively would be to process your photos in conditions where all the factors affecting subjectivity, i.e. the colour temperature of the ambient light, is the same as when the photo was shot. In my Canon 5D Mk III, for example, this could be done as follows: Shoot the ...


But there is nothing objective about perception. If the goal is to attempt to reproduce the perception, the closest will be to set the white balance from a grey card which is not directly lit with the Sun.


There is no justification for removing JPEG processing in digital cameras for the foreseeable future, there are plenty of reasons not to use jpeg but none to make it completely unavailable. From a performance perspective the biggest bottleneck is writing the file to storage card(s) and mandating bigger files would yield no speed improvement at all. Cost ...


When it comes to the sun, objectivity is harder than that. Color of the setting sun is changing while it's descending - and white balance basically means that you choose the light of the sun as white point. It differs minute-to-minute in last stages of sunset, but overall - you should decrease color temperature if you want to set white balance correctly ...


Nope. From a manufacturers point of view, it wouldn't even be a different camera. They'd sell the exact same camera with some firmware that prevented jpeg compression. When it comes to integrated circuits, mass production is where the money comes from. A product with reduced feature set is often just cannibalised with a special firmware. I remember how I ...


I'm a little unclear what you're asking, but if you literally want to measure the color temperature of the light from the setting sun, you can take a photograph of the setting sun in raw mode, making sure not to overexpose the disk of the sun. Then, in your processing software, you can set the white balance by clicking the eyedropper on the disk of the sun. ...


Even though the files from your new 7DII are in the .cr2 format, the data in a raw file is always sensor specific. That is, each different sensor design must be demosaiced/converted differently to get the same standardized results. Lr 3 is a while back. The latest version of Adobe Camera Raw (which is used by Lr to demosaic raw files) that is compatible ...


Yes; if you edit the image (for example, to resize) and save, there will be new degradation from JPEG artifacts. If you saved (and resave) at a very high JPEG quality, the difference will be negligible. You could avoid this by saving in a lossless format like TIFF instead after your edit.


Interesting to consider what "color temp" or "WB" causes the monitor to show the actual same color. The same spectra would indeed be the same in a real sense. But we don't have that. The same tristimulus RGB values should "look" the same, at least to a primitive stage in processing in the eye. But the brain interprets that based on the brain's own WB ...


ACR is not a stand alone application, but a Photoshop/Bridge plug-in. But if the file extension of your raw files is associated with Photoshop, PS should load and the file should open immediately in ACR when you double click it from explorer. Functionally, there is no difference then to your requirement. What your own browsing program does is, of course, ...


I know this question is old, but just for anyone still looking Amazon Clouddrive is offering unlimited photo storage for $11.99 a year, which includes RAW files.



According to Adobe's Camera Raw Supported Cameras page, the A58 requires Camera Raw version 7.4 According to their Compatible Adobe applications page, CS5 only supports ACR plugin version 6 (6.0-6.7). Are you using CS6? If so, should be able to update camera raw as high as version 8.71, according to that page.


Welcome to the Photoshop tax on new cameras. :) Essentially, RAW is not an acronym or a file format or a standard. It's a raw data dump from the sensor/processor. And it's different for every single camera model. The CR2 files from your 7DMkII are different from the CR2 files of your 7D. And since Adobe has no time travel capability, they can only ...
