A camera is part of a system; So lets look at that system. I'm going to make generalisations and some assumptions - don't get upset if they're wrong. Since you are looking at a D5300 it gives a good indication that your budget is relatively low. You're not really going to be using jpeg, so we're looking to see if there's enough value in the uncompressed ...

The particular lossy compression used here is nothing to worry about. Here's why. Camera sensors are more or less linear devices, if you double the amount of light you double the signal produced by the sensor. Our eyes work logarithmically, so if you double the amount of light, it appears much less than twice as bright. Another example of this is if you ...

Even with lossy compression the NEF file still contains a lot more information than a JPEG file. There is considerably more data per pixel in the NEF file. Even if the 14 bits color depth is reduced somewhat by the compression, it's still way more than the 8 bits of a JPEG image. You won't see much difference between the JPEG and the NEF in a direct ...

If you do no editing, such as adjusting light curves, color balance, white point, sharpening, etc. prior to converting to TIFF or JPEG, then the only difference between the finished files will be whether you allowed the automated routines in the camera make the decisions (JPEG) or the preset/automated routines in your conversion software application make the ...

14-bit tiffs use more 1s and 0s per pixel than jpegs by a ratio of 16384 to 256. Raw files store a little more data in the highlights and the shadows of an image, allowing you to better recover shadows or highlights. When your camera takes a jpeg, it will perform edits on that picture, such as white balance and sharpening changes. If you were to edit one ...

On the Canon website, look under 'software' rather than drivers. Download and install the Canon RAW Codec 1.11.0 Alternatively, you can try FastPictureViewer, which is a 3rd party codec pack that support lots of raw file types including Canon. It also supports PSD, which is nice as well if you use Photoshop. There is a trial version to try, otherwise its ...

Few (if any) of the codecs in the pack were built by Microsoft. They've been supplied to Microsoft by the camera makers to be repackaged in the same way that most device drivers are not written by Microsoft either. The codec pack can be used by any application that supports WIC (Windows Imaging Codecs). Paint.Net is one popular free (as in beer) ...

the microsoft image looks over saturated to me, which has increased its acutance at the petal edges..but my guess is it has less dynamic range than the others , and reduced palette. i wouldn't personally want to mimic what its doing..but thats subjective. my guess is windows is applying a different gamma curve . since the others look roughly the same, id ...

I am with Eyefi and I would like to see if we can get this sorted out for you. It sounds like you may have a standard Eyefi Mobi card. What color is your card and what is the GB capacity? If it's an orange 32GB card, its a standard Mobi card, which only transfers JPEG files via WiFi. If it's a black 32GB card, then it is an Eyefi Mobi Pro card and I would ...

If you go to photoshop edit/preferences/camera raw / 'save image settings in' - choose sidecar xmp files. I don't know why it works, it just does. My cs4 was driving me nuts as everything I opened was 8 bit, even though I'd previously opened the same raw file a few months ago and it was 16 bit. I couldn't find the ACR screen by the way in cs4 or bridge - ...

I know you want to use ACR, but I believe if you use Lightroom you will have access to the whole image. If it doesn't appear by default you can adjust it with the crop tool. If you have Lightroom set up to always write XMP files, maybe you can then open the file in ACR with your preferred crop.

There are several reasons to shoot RAW and JPEG: Just to recap: RAW is the information the camera gathers from the sensor, without (or just a bit) modification. JPEG is a lossy compressed image, which is created out of the RAW file according to your settings of film simulation, dynamic range optimisation, noise reduction and so on. In short, it misses ...

I overcame the problem by converting NEF files to DNGs with Adobes converter. And I conclude that RawTherapee just doesn't know how to handle NEF files properly, since AFAIK with DCP profile file it should work correctly. While this is not a solution to the problem but a workaround, I'll leave an option open for others to solve the problem and this answer ...

NEF files show the raw sensor data, which is linear. It is quite common that the maximum intensity in a NEF file might be a small area of highlight, and the main body significantly less. The different colors also have different sesitivities. Typically NEF files have a overall green cast if viewed without any adjustments. This is all normal and as ...

Found it here in the RawTherapee documentation: In Colour Management, you can select an output and/or working colour space. Most likely, you selected one ending in _g10, which denotes a colour space with linear gamma. RawTherapee's main histogram and clipping indicators will also be based on the output profile. Ordinary sRGB has a gamma of 2.4 ...

I haven't directly experienced this, but have heard of cases where a camera setting for "protect highlights" (or similar) results in the camera deliberately under-exposing, then compensating for it in the JPEG engine while protecting the nicely captured highlights. This compensation, of course, will not be reflected in the RAW file, and software not provided ...

As I don't have any extra photo editing programs I used iPhoto to do this. Open iPhoto with the option key held down. This gives you the option to create a new library. Create a temporary one somewhere where it will be easy to find and delete it later. Import all the Raw Pictures into the new library. Export them all in the required format. Quit and delete ...
