Much of the information encoded in a JPEG is baked-in, meaning that any edits done to the file are destructive and there will be a slight loss in quality. Image quality options with a star next to them use compression intended to ensure maximum quality; the size of the files varies with the scene. Options without a star use a type of compression designed to produce smaller files; files tend to be roughly the same size regardless of the scene recorded.
You can actually change the compression settings of a JPEG by selecting whether you want it to give priority to image quality or file size in the camera. That means more time will be spent on post-production since you must edit your files but it also means you can make many different edits without any loss in quality thanks to the non-destructive nature of the file.
What software can you use to edit the RAW files? A JPEG is smaller and can be shared right out of the camera while a RAW file is much larger and must be edited before it can be shared. A JPEG is an 8-bit file, which means each channel red, green and blue in a pixel can record up to levels of luminosity. By multiplying each channel together x x you get a theoretical maximum color depth of 16,, This means that an 8-bit file has the ability to show up to On higher-end Nikon cameras you can select whether you want the RAW file to be recorded either as a or bit file, which will give you an incredible 1.
Why and When to shoot at the highest bit quality is a topic for another article but the important thing to take away from these numbers is not that more colors are possible when shooting at a higher bit-depth, but that tonal gradation the steps in between colors are much finer.
Look at it this way: all cameras technically shoot RAW. Record Greater Levels of Brightness Levels of brightness are the number of steps from black to white in an image. The more you have, the smoother the transitions of tones. Smooth is good. The effect this has on your images is huge. So, you wind up with a dramatically over or under exposed image.
You can also recover more blown highlights and clipped shadows. Good stuff. Get Better Detail When you shoot RAW you have access to sharpening and noise algorithms in a program like Lightroom that are way more powerful than those found in your camera.
And jetpacks. You can always reset your adjustments, and start over again. Are the files heading to a client? Save it in the common Adobe RGB colour space. Do you want the widest colour space possible? Now, there are always pros and cons to every option, and RAW does have a few disadvantages. Yes, RAW files are bigger and take up more space. Wrap It UP!

But what about if you are not going to process your photos at all? Or what if you need to send the photo from your camera right away? Why not take both? Your camera will likely have a setting allowing you to do both so that every time you take a picture the camera is creating a RAW file and a JPEG.
That would allow you to have all the advantages of both file types. How might that benefit you? Here are a few ways I see:. But wait a second, you might think. Surely these are really minor advantages. Why bother with all that?
Why not just use the RAW file? Yes, these are really minor advantages, but at the same time, what is the cost? This leads to reduced number of shots during continuous shooting. All the advantages of RAW mentioned above is post-editing related.
In order to display the photo in its optimal quality, you need to know the photo requirements of the social networking site you use. For example, Facebook will compress a photo which is larger than px, and changing the Color Profile to sRGB will work best.
Therefore, for Facebook users, always resize photos to px and save in sRGB to ensure optimal quality. Original image. Original image px uploaded to Facebook. Resized image px uploaded to Facebook. Look closely and we can see that the stain on the glass is less smudged on the px photo left than the original photo right. The above are a brief introduction of RAW format and the best setting to upload photos. Please take these as reference and find the format and way to upload that work best for you!
