Given an image how to identify whether it is RAW file or not

Once I've a JPEG photograph image file, how can I find out whether it is a RAW file or not? If you have a JPEG file, then it is not a RAW file. RAW isn't a single format, but rather a collective ...

My mentor says to set image to Fine instead of RAW — how is this different from JPG?

you don't have to reproduce the algorithms that the camera is running to render your photo on the small display on the camera. This all depends on how much you value what is shown on the camera's LCD ...

Given an image how to identify whether it is RAW file or not

Unless somebody frivolously renamed a RAW file, it will never have a file name with the .jpg/.jpeg/.jfif extension. Typical extensions for RAW files will be .raw, .arw (Sony), .dng (Android phones etc....

JPEG, as you know, is a lossy compression format. One feature of the format is different quality levels, which correspond to greater or lesser amounts of information discarded to save space. See Is ...

RAW in ACR vs JPG in ACR

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 ...

Good examples of RAW's advantages over JPEG?

Because RAW doesn't discard information through lossy compression (like JPEG does), you can often recover some smaller detail by manually processing the RAW file. The example below provides an ...

What are the pros and cons of deleting all of my archived RAW files?

Pros: You gain some space. Cons: You won't ever be able to change your mind. A 4TB drive is about $£€70 these days. Buy one, stack all your old data on it & put it on a shelf. If the drive does ...

The biggest thing that is missing from a work flow of "Just blast it all away from the command line" is that of conscious control. And deleting your raw files to save space might leave you missing the ...

Is there any benefit to RAW+JPG being two separate files on Nikon?

I expected that this would cleverly embed the JPG within the .NEF file structure so I could handle them as a single unit. When you record a raw file, the camera almost always embeds a jpeg preview ...

Why RAW and JPEG look the same?

This is normal. The software you are using is showing you the JPEG preview embedded in the RAW file, which in every case I know of the same as the JPEG generated with RAW + JPEG settings. (Depending ...

Why does the chart for my Canon 77D show more photos saved with RAW + JPEG than it does for RAW alone?

It looks like the value for only RAW files should have been 270 instead of 170. Multiplying the average file size given by the corresponding shot count yields values between approximately 7GB and 8GB ...

When shooting RAW + JPEG , is there a way to delete the raw files without deleting the corresponding JPEG, without having to hook it up to PC/laptop?

My Canon cameras also behave like this and AFAIK this is standard behavior for all cameras. Assuming 40-50MB for a JPEG+Raw pair you can still put over 1200 shots in a 64GB card. This is quite a lot. ...

Why can software correct white balance more accurately for RAW files than it can with JPEGs?

The simple answer is because your camera and your RAW processor (LR, Darktable, to name few) use different algorithms to process RAW files. The reasons are many, and we can't evaluate those algorithms ...

There is a simple way to do exactly what you want, but unfortunately cannot be done with the D5600 (or any camera with a single card slot). On Nikons with 2 card slots, you can set it so that all the ...
