Understanding Camera Raw: The 'A' Mystery Explained

The a in camera is silent because the word comes from Latin, in which the a is not pronounced. In Latin, camera means vaulted room or arched room. The word was later adopted by artists to refer to a room where paintings were displayed, and eventually came to refer to the devices we know today that capture images.

RAW files are uncompressed and contain a lot more image data than a compressed file like a JPEG

An uncompressed RAW file preserves all of the data in an image without compression. As all image data is stored with no impact on quality, you have the freedom to manipulate aspects of the photo like brightness, colour, sharpness, and noise reduction with minimal quality loss. This is the largest RAW image file size.

JPEGs, on the other hand, are compressed files. Compression in photography is the process of reducing the size and quality of your photos, which is why JPEG files are smaller than RAW files. When you edit a RAW camera file, you get far more leeway when it comes to bringing out dark areas and recovering overly bright areas. You also have more flexibility when it comes to colour temperature, which is how warm (reddish) or cool (bluish) an image looks.

While RAW files offer more flexibility and forgiveness for errors, it is still best to get your exposure as close as possible in-camera. This is because RAW files are much larger than JPEG images, so they take up more space on your memory card and hard drive. They also take more time to record, which is why photographers sometimes revert to JPEG to get the most speed from their gear.

This means you have a lot more flexibility when it comes to editing a RAW file

RAW image files contain a lot more data than traditional JPEGs, and this gives you a lot more flexibility when it comes to editing. RAW files are unprocessed, or minimally processed, and contain large amounts of data from the image sensor of a digital camera. This means that you can make adjustments to the image after it has been taken, without losing any of the original data.

With a RAW image, you can make all the adjustments in post-production. You can edit the white balance, contrast, colour space, and sharpening, without limiting your ability to modify the image further down the line. This is because RAW files contain a wider range of possibilities inside image editors like Adobe Photoshop and Lightroom. For example, you can add more contrast to a RAW photograph by adjusting the highlights, lights, shadows, and dark areas of an image separately.

Correcting the white balance on a RAW file, or making exposure corrections, doesn't harm the integrity of the shot. This is because the RAW file contains so much more data than a JPEG. You can also adjust the settings on a RAW file to settings that aren't available in-camera.

The downside of RAW files is that they take up a lot more space, and it takes longer to record multiple RAW images in a row than it does for JPEGs. This means that photographers often revert to using JPEGs when they need to capture images quickly, or when they need to conserve memory card space.

However, if you want to be able to do more with your images in post-production, and have more flexibility when editing, then shooting in RAW is the way to go.

You can shoot in RAW+JPEG, which gives you the flexibility of RAW with the convenience of JPEG

Shooting in RAW+JPEG gives you the best of both worlds. RAW files are technically superior, offering greater dynamic range, more colour information, and an adjustable white balance. However, these benefits can only be appreciated when post-processing files. So, for photographers who don't want to edit their files, the advantages of RAW photography don't apply.

JPEGs, on the other hand, are compressed versions of RAW files. They are more convenient as they are processed by your camera, so you can share them instantly on social media. They are also smaller in size, which means you can store more images on a single memory card.

Shooting in RAW+JPEG gives you the flexibility of RAW with the convenience of JPEG. You can use the JPEGs for quick sharing and the RAW files for more detailed editing. This is especially useful for event photography, where you can quickly deliver JPEGs to clients or for social media posting while retaining RAW files for high-quality editing and album creation.

Another advantage of shooting in both formats is that it future-proofs your photos. If you are shooting RAW files with a particular camera model and that camera model is discontinued in the future, your RAW files may lose support over time. This is less likely to be an issue with JPEGs as they are a more widely supported format.

Additionally, shooting in both formats allows you to see how your camera processed the JPEG file, so you can mimic that effect when editing your RAW files. This can be helpful when you are just starting and learning how much processing to add to your photos.

However, there are a few drawbacks to shooting in both formats. Firstly, it will consume more space on your memory card and require larger storage solutions. Secondly, it will slow you down a little bit as your camera has to write an additional file each time you take a picture. Lastly, it can be frustrating and time-consuming as you have twice as many files to manage and it's easy to accidentally work on the JPEG instead of the RAW file.

RAW files are not universally recognised, so you will need specific software to view and edit them

RAW image files are not processed or are minimally processed by the camera, which means they need to be interpreted by specific software to yield a viewable image. This is in contrast to JPEG or PNG files, which are already interpreted by the camera's software and can be viewed universally.

Each camera manufacturer uses its own RAW file format, such as ARI, CRW, PXN, RAF, RWZ, SRF, DNG, RWL, RW2, and KDC. This means that you will need a codec or driver that supports your specific camera model to open and view RAW images on your device.

There are several software options available that can be used to view and edit RAW files. Some popular options include:

• Adobe Lightroom
• InPixio Photo Studio
• Adobe Bridge
• CorelDRAW
• FileViewer Plus
• ACDSee Photo Studio

Some of these software options are available for free, while others require a purchase or subscription. It's important to note that not all photo editors can handle RAW files, so it's important to check the compatibility before choosing a program. Additionally, some cameras offer their own software that can be used to view and edit RAW files.

While using RAW files requires an extra step in the photo editing process, it offers several benefits. RAW files provide more flexibility and control during post-processing, allowing for more accurate corrections and adjustments to the image. They also contain more data, resulting in higher-quality images compared to JPEGs.

RAW files are much larger than JPEGs, so they take up more space on your memory card

RAW files are uncompressed and unprocessed, containing all the data captured by the camera's sensor. This results in significantly larger file sizes compared to JPEGs, which are compressed and processed in-camera.

The size difference between the two formats is considerable. A 16-megapixel camera will produce a 16 MB RAW file, while the equivalent JPEG will be approximately 5 MB. This means that RAW files can take up three to six times the amount of space as JPEGs.

The larger file size of RAW images means that memory cards will fill up faster, and you will be able to capture fewer images before needing to swap cards or transfer files. This can be particularly noticeable when shooting in burst mode, as the camera's buffer will fill up more quickly with larger RAW files.

The increased file size of RAW images also impacts storage requirements. When shooting in RAW, you will need to ensure you have sufficient storage space on your memory cards, as well as additional hard drive space for backing up and archiving your images.

While the larger file size of RAW images can be a disadvantage in terms of storage and memory card capacity, it is a trade-off that many photographers accept for the benefits that the RAW format provides. RAW images offer greater flexibility in post-processing, providing more detailed data to work with and allowing for more extensive adjustments without a significant loss in quality.

In summary, while RAW files are much larger than JPEGs and require more storage space, they provide photographers with uncompressed, unprocessed data that offers greater flexibility and control in the editing process.
