Why You Should Shoot Raw

Before we go anywhere, we should answer the question, what is RAW. Well the word itself is the clue, put simply a RAW file is just the raw data from the sensor put into a readable file format. No adjustments of any kind are made to the image, it is purely a digital representation of the light that hit the sensor during exposure.

There used to be many arguments against using RAW in the early days of digital photography. It takes too much space, the post-production is complicated, will there be compatible software in 30 years? I don’t have big enough memory cards to use RAW. Many of these arguments will still be trotted out today so let’s dissect each one.

Too much space – hard drives today are not only cheap, but they are massive compared to just a few years ago.

Post production – well there is an array of image management programs out there now, all very capable of reading and adjusting RAW files. If you are on a Mac, you will already have some great-inbuilt software in iPhoto. Even Photoshop’s Raw program is a lot simpler than in days gone by.

Compatibility – well first you are making the assumption that either your camera manufacturer will go bust or stop supporting older formats. Both are unlikely but if they did occur, think about how many freeware programs that are out there running or emulating 20 year old software. If there is a need, someone will write the code.

Lastly memory cards – well it’s more or less the same response to hard drive.

So why should we use RAW? Put quite simply, its better. First and foremost, you will be able to attain the highest possible quality that your sensor can deliver. When you shoot JPEG, you camera makes all the adjustments based on your settings then applies them to a file that is then compressed. It’s a double whammy, the image is already manipulated then it is reduced in size.

With a RAW file, you make all the corrections in the post-production getting the image perfect before you save it as a JPEG. The latitude and dynamic range of a RAW file is significantly higher meaning if you are struggling with a difficult exposure you are more likely to be able to “save” the image in post.

RAW captures a higher dynamic range

You can also correct your own mistakes, have you ever returned home to find you have shoot the wrong white balance or wrong image size. RAW files do not apply white balance so you can be way off with the original camera settings yet return the image to perfect in post, and the image size is always the maximum dimensions of the sensor.

RAW allows for much more image manipulation without loss of quality

Because of the increased dynamic range of RAW files, it is possible create effective HDR images from a single file simply by post producing two or three different exposures from that single file.

One of the unsung hero’s of RAW files in my opinion is being able to control and protect your intellectual property. If you strictly control your RAW files, and only release into the public domain, JPEG’s or TIFFS, you have a very strong argument if you incur copyright infringements.

Whilst there are a few minor problems shooting RAW for instance, older cameras may slow down when shooting in burst mode, the pros far out weigh the cons. If you are looking for maximum quality and control over you images then RAW is the way to go.

    I don’t shoot raw and as a result I am forced to make sure my settings are correct at the beginning of the shoot. A friend (who is not a photographer but IS a news director) suggested sometime back that it is more effective time wise to do as much “editing” in the shoot (or camera) as possible to save time in post production. He is a wise man and that little piece of advice has made me a much better photographer as a result. I get great results coming out of the camera (not all pix but far more than I can use) which means I can spend more time cropping for composition if I wish or just have a faster turnaround time with hugely better results than an amature that downloads straght to the internet. Jepg, ok but isn’t it about what ya can put on paper for the client anyway! When I say paper what I mean is a hardcopy or even a reduced file for the internet. I don’t think of my work as throw aways and I always save my originals to disk so why again should I shoot everything raw? Serious question and whould like an answer =0)

    That is an interesting comment, likening a raw file to an archive in the JPEG as the display image. As a photographer who transitioned from using film to using digital, I use raw files when I know I’ll want to pull out the latent information in the raw file. While our cameras have five stops of latitude (2-1/2 up, 2-1/2 down) I like to try and capture some of the latent info, especially blue skies.

    Thanks for this post. I find that as an amateur photographer, I avoid raw because I seldom get an amazing shot that even warrants a lot of post work

    When I was beginning I thought that RAW was a waste of time and space. Later as I learned more about the format it was obvious that it is worth having the RAW file. However it is no excuse for getting sloppy. If you blow the whites too much even the RAW file cannot save them. Now with that said, there is a middle ground. I shoot everything as RAW+JPG finest. If I get to the post work and there is a problem with an image like the white balance off by a hair or the exposure a tad off, I drop to the RAW file and do the hard work. On the flip side if the JPG is good I just work with that and it greatly shortens the post time. However this does eat up hard drive space and CF cards fill up faster, but as you mentioned they get bigger and cheaper every day. One other point not mentioned is that a JPG is an eight bit image while a RAW file is 14 bits and most RAW editing programs work on them in a full sixteen bit environment, so the editing is much finer. Shadow recovery, noise reduction and highlight control is very much improved in the 14 bit range where working on an eight bit JPG can be harder to achieve good results with.
