These Are the Advantages and Disadvantages Of Shooting Raw

Raw files (the correct files format differs from manufacturer to manufacturer) are simply a “digital negative” of your image (but aren’t negative at all, only referred to that way in reference to the film era). In Practical terms, a raw file is all the bits of information the sensor captures, packed in one file without any compression or loss. But why would anyone need all that info? After all, raw files are 10x larger than jpegs, right?
Yes, and it means they contain much more information. If you edit a raw file and need to brighten the shadows and equally tone down the highlights, you won’t lose any detail (if done in moderation of course and if there is no clipping). On the other hand, with jpeg you don’t get much more than what you see.

Furthermore, with all that extra information in a raw file, image processors can do real “magic” with the image. First and foremost, raw files allows for greater general feature manipulations, meaning that adjusting contrast, brightness, shadows, highlights, and so on will not look bad and you can go to greater extremes than with a jpeg file.
More so, white balance: you can practically forget about setting the right white balance when shooting, since you can change it completely when editing the raw file without any issues and it will still look the same as if you set it in camera.
Going further, sharpening done on a raw file (not really on the file, but using the info it has and doing it on a copy) is way better with more advanced plugins since they can use all the information the file has in order to optimize sharpening on the edges, and therefore, avoid further noise generation.

While we mentioned noise above, many noise reduction plug-ins can use raw files to generate better output. With plugins that use raw files in noise reduction (including Camera raw from Adobe), the difference in the retained detail is immense.
Above all, raw files really do add a whole lot to the quality of images. However, there are some things that might get in the way for some photographers and many regular snap shooters.
A raw file isn’t a photo. Without plugins for Windows/Mac/Android and so on, you can’t really see the image since it is a digital negative. And as a regular negative, it needs to be developed via photo processing software which supports Raw (Photoshop, Light room, and so on). This means you are best advised to process the raw files first. You can however, set your camera to shoot raw+Jpeg, but you can forget about long bursts.

What About Raw File Size?

Oh man, the files are getting bigger and bigger with increased resolution in newer cameras. For instance, we have 15-25 MB for a 10 megapixel raw file. Even so, just imagine the file sizes on 24 or even 36 megapixels, it can be very staggering! Even though memory cards are advanced enough to hold at least a thousand high resolution raw files, for the regular shooter, it can mean terabytes of raw files within 6 months. Your library will certainly get bigger, so that you’ll need additional hard drives for backup and so on.
The file size also brings another problem: bursts; rapid fire fills the buffer up to 4 times faster. However, on modern day cameras it is not that short, so you could get out 20-30 frames before the buffer fills.

Other disadvantages?
Well besides the file size and occasional inconvenience of processing your images, there aren’t any other disadvantages.
Really, my current shutter count is around 120.000 and every single shot is in raw (there are a whole lot in raw+Jpeg too). Since I bought my DSLR, raw has been the file type of choice for me; unpack the camera, power it on, set to raw, and then see how the rest works.
One additional Note
Image processors and organizers, such as Lightroom, Phase One, Aperture and so on are advanced enough so that exporting jpegs from raw files will take you just a few minutes. For straight up conversion. i.e. to avoid confusion, .cr2 is the raw file that Canon cameras produce, while .nef is the raw file that Nikon cameras produce. Adobe software has something similar to raw file called digital negative (and has the .dng extension), and many photographers convert their raw files into .dng because they are slightly smaller and other manufacturers have raw file names as well. In fact all cameras with interchangeable lens have the ability to shoot in raw file format.
Nowadays even smart phones are bringing the raw files to the table. With the considerable advantages in shooting raw, it's something worth considering for your own work.
