RAW (Image)

File extension .raw
Category Image File
Description The RAW file format contains untouched raw pixel information that comes straight from sensors of a digital camera. In digital photography it is the equivalent of a negative from traditional film-based photography. Digital Cameras process the RAW file by changing it to a full colour JPEG or TIFF image file that is stored on a memory card for a camera, but it is usually possible to retain the original RAW file too. Generally as the RAW file comes straight from the sensor this gives photographers more control over how the final JPEG or TIFF image is displayed.

There is no single RAW format. Digital camera manufacturers have each developed their own proprietary (often undocumented) formats, often changing the format from one camera model to the next. Several major manufacturers, including Canon, Sony and Nikon encrypt elements of the file to prevent 3rd party tools from accessing them.

RAW file contain uncompressed and untouched raw image data from Panasonic, Leica, and Casio cameras. These RAW files are also sometimes called digital negatives. The purpose of raw files is to get maximum information from the sensor of the camera to give possibilites to adjust the image later (e.g. white balancing and color grading).

JPG, also known as JPEG, is a file format that can contain image with 10:1 to 20:1 lossy image compression technique. With the compression technique it can reduce the image size without losing the image quality. So it is widely used in web publishing to reduce the image size maintaining the image quality.

Unlike other file formats and extensions, the term RAW is not an acronym or an initialization. Instead, it means exactly what it says. A RAW file is an unprocessed image with all of its original information intact, as captured by the camera’s sensor. Information can include the conditions that were present when the picture was taken, as well as descriptive text. Both open-source and proprietary RAW file types currently exist.

How to open a RAW file?

The best way to open a RAW file is to use the software the camera manufacturer developed specifically for that purpose. Determining the manufacturer is easy because they assign their own extension to RAW files taken using one of their cameras. For example, Canon (CR2), Nikon (NEF), Sony (SR2), Epson (ERF), Kodak (KDC), Panasonic (RW2), and others.

Alternatively, you may use a universal image viewer, such as Adobe Photoshop, Adobe Lightroom, or Zoner Photo Studio (an alternative to Adobe products). After post-processing (editing) RAW files are usually converted to a JPEG (RAW to JPG), PNG, TIFF, or BMP file type. To open RAW on Microsoft Windows or macOS, use the options described above. For Linux/Unix, you can use darktable. For a multi-platform viewer, try XnView MP.

What is a JPG (Joint Photographic Experts Group) file?

JPG (Joint Photographic Experts Group), is a universal file format that utilizes an algorithm to compress photographs and graphics. The considerable compression that JPG offers is the reason for its wide use. As such, the relatively small size of JPG files makes them excellent for transporting over the Internet and using on websites. You can use our compress JPEG tool to reduce the file size by up to 80%!

If you need even better compression, you can convert JPG to WebP, which is a newer and more compressible file format.

How to open a JPG file?

Almost all image-viewer programs and applications recognize and can open JPG files. Simply double-clicking the JPG file will usually result in its opening in your default image viewer, image editor, or web browser. To select a specific application to open the file, utilize right-click, and select “Open with” to make your selection.

JPG files open automatically on popular web browsers such as Chrome, Microsoft applications such as Microsoft Photos, and Mac OS applications such as Apple Preview.

People usually buy professional-grade cameras to get the best image quality possible. However, soon they find out that the best results come from saving images in RAW format, which come in different formats, depending on the camera manufacturer: CR2 (Canon), NEF (Nikon), ARW (Sony), and more. These RAW files retain the unprocessed information from the camera’s sensor, saving as much visual information as possible. Retaining this much information is important for ensuring optimum quality, but the downside is it makes the files pretty large. Additionally, not many photo editing programs provide good support for RAW image formats, which means that you may find you can’t open or edit these files on a computer.

So, for practical reasons, one of the best ways to deal with the aforementioned problems is to convert RAW files to a more convenient and flexible format like JPEG (JPG). This image format is more universal and is supported by almost every device, so you won’t have any trouble viewing or editing the files. Plus, JPEG files are much smaller, making them much more flexible for storage purposes, especially if you have a lot of images.

In the guide below, we cover RAW-to-JPEG conversion as well as the difference between these two formats.

How to Use Movavi’s RAW-to-JPEG Converter

To safely convert RAW to JPG without problems, you will need a good file conversion program. In this case, a great idea would be to try Movavi Video Converter. Despite being designed a video converter, the program easily converts between all popular image formats, including PNG, GIF, TIFF and other still image formats. And with the help of the batch conversion feature, you can convert your RAW photo library in the shortest time possible.

Digital SLR cameras can take photos in RAW format, which is a bit tricky for our photo book creator since it only recognises images in JPEG format. Below you’ll find out how to convert your images from RAW to JPEG format – it looks a bit complicated, but it’s ok really (if you get stuck and need a calm voice to explain things, our customer service team would love to help).

1. What does ‘RAW format’ mean?

2. Convert your file

Open the photos in RAW format, e.g. in Photoshop. Go to ‘File’ and choose ‘Save As’ and select from the list ‘.jpg’ (it might appear as JPEG).

Choose a compression between 90-100%, otherwise this leads to loss of quality. Compression also reduces the file size. Note: Make sure the settings are RGB.

3. Image size

For a 30×30cm book, your photos should be a minimum of 12 inches x 120 dpi or 1440 pixels wide to be displayed on a full page. Any smaller than this and the resolution in your photo book won’t be clear.

If you’d like to stretch a photo across two pages (30x60cm), it needs to be twice as large, i.e. (2 x 1440) = 2880 pixels. You can use the same formula for larger or smaller sized photo books. If you’re in doubt, our ‘Resolution warning’ in the photo book creator will tell you if your image isn’t large enough.

4. Difference between RAW and JPG

Ok, are you sitting comfortably? We’ll explain… a RAW file is added to include information about camera settings. Most sensors can be 12-bits to store colour information per colour channel. This means that each of the Red, Green and Blue (RGB) 4096 variations can be saved.

When saving a picture in JPEG format in the camera, the 12-bit information is converted to the 8 bits in a colour channel can have a JPEG file.

In JPEG format, there are only 256 possible variations per colour channel. In practice, these extra colours are not visible to the human eye, but of course it means that information is lost. For example, shadows and light parties through processing of the RAW format this additional information to be highlighted with a photo editing program so that way in shadow and light by drawing lots more to see.

Downside is that pictures taken in RAW format are stored much larger files and rework have to optimize them for printing. This is a time consuming process and it requires the knowledge and practice in this way the most of the pictures to take.

2. Choose where you wish to save the outputted JPG’s. It’s easier to save them in the same location though for convenience. Photoshop will automatically create a separate folder containing these JPG’s.

3. Choose the format that you want to save the RAW files to. In my case it’s JPG’s, but you are given the option to save to TIFF or PSD as well.

4. In the final step, you are also given the option to run an Action on all of the RAW files whilst saving them to the specified format. This can be another big time saver. The other option is to include the ICC Profile (International Colour Consortium) This will be checked by default. I will always keep this checked.

RAW FILE FORMAT

Also known as “digital negatives”, RAW photos are uncompressed images that include all the details captured by the camera’s sensor. They need to be post-processed . See more using an advanced image editing software. Shooting in RAW mode allows the photographer to have more control over how the image will eventually look, compared to the case of other compressed formats, such as JPG or PNG. The downside of using RAWs, however, is their enormous size, which makes them difficult to store and transfer.

JPG FILE FORMAT

JPG is one of the most popular image file formats currently in use, often referred to as a standard for uploading images online and for displaying photographs. . See more One of its main advantages is providing a good image quality in a relatively small file size, which is easy to store and transfer. JPG uses a type of compression that prioritizes the quality of some image sections over others, thus assuring that most favorable quality/size ratio.

Your frame is 2457600 bytes and your pixel dimensions are 1280×960, so you have:

You can get a list of the pixel formats that ffmpeg supports using:

Sample Output

That means you can get a list of pixel formats that contain Y , U and V with 16 bits per pixel like this:

Now you can run a loop, iterating over all the 16-bit per pixel YUV formats and see what ffmpeg makes of your image – naming each result after the format so you can identify which is which:

That gives you these files:

And I guess that yuyv422.jpg is your image, so that means you can extract it with:

How to convert raw files to jpg

If you wanted to do that with ImageMagick, you could do something like this:

If yo don’t like/have Python, that part can be replaced with some basic C as follows:

Having had so much fun doing ffmpeg , Python, and C versions, I thought I’d try just doing it in the shell – converting bytes to lines and so I could pick alternate lines instead of alternate bytes. This works the same as the above:

As regards colour cast removal, as I said in the comments, the " normal" way, AFAIK, is to get the average colour of the image and invert its Hue then blend that "negated cast" back with the original image to offset the original colour cast. Here is a crude attempt – if anyone knows better please ping me!

Step 1: Get average colour cast

Step 2: Invert the cast

Step 3: Blend the original with the correction and brighten maybe

Here are the original and corrected versions:

Obviously you can change the percentages for different degrees of "correction".

Should I look for another tool, or the only option is to write some loop around convert ?

Imagemagick cannot convert raw image files in recent Ubuntu versions because the ufraw-batch package is not available, due to it not being maintained anymore. We can however use darktable do the conversion. To install darktable run:

You can then use this command that uses darktable-cli to convert the images:

The above command uses find to do the following:

  • recursively search in the current folder: .
  • for files only: -type f
  • that their name ends either in .raw or .nef , irrespective of their case: \( -iname "*.raw" -o -iname "*.nef" \)
  • executes ( -exec ) this command to convert the found files to jpg: sh -c ‘darktable-cli <> $<0%.*>.jpg’ <> \;
  • deletes the original files: -delete

Caution: Make sure to first test the command in a copied portion of your files to ensure that it works as intended!
