What is the difference between RAW format and TIFF format

1. TIFF is a lossless compression format, while RAW is simply the original unprocessed format;

3. TIFF cannot be exposed to light adjustment, but RAW can be exposed to adjustment;

4. TIFF tune** may be lossy, RAW tune is lossless.

One, TIFF is a ** format, that is, the label image file format (tagged

imagefile

Format, abbreviated as TIFF), is a flexible bitmap format that is primarily used to store images including ** and art. It was originally developed by Aldus in conjunction with Microsoft for Postscript printing. TIFF became a popular high-bit color image format along with JPEG and PNG.

The TIFF format has been widely supported in the industry, such as Photoshop and THE

PhotoImpact and Paint

Image processing applications such as ShopPro, QuarkXpress, and Adobe

Desktop printing and page layout applications like InDesign, as well as scanning, faxing, word processing, optical character recognition, and other applications support this format. Adobe, which acquired the PageMaker print app from Aldus, now controls the TIFF specification;

2. The original meaning of raw is "unprocessed". It can be understood that the RAW image is the raw data that the CMOS or CCD image sensor converts the captured light source signal into a digital signal.

A RAW file is a file that records the raw information of the sensor of a digital camera, as well as some metadata (metadata, such as ISO settings, shutter speed, aperture value, white balance, etc.) generated by the camera. RAW is an unprocessed and uncompressed format that can be conceptualized as "raw image encoded data" or more figuratively referred to as "digital negatives". The full name of the RAW format is RAW

imageformat, which is called primitive in programming.

TIFF is a lossless compression format.

Raw is simply the original format.

TIFF cannot be exposed to light adjustment, while RAW can be exposed to adjustment.

More information entropy concept, ** file as much as possible to use high depth to record the collected data, so it seems that both seem to be high depth, but the difference, TIFF has a defined color space and RAW color space is defined later, that is to say, the analog to digital signal file recorded by RAW has a higher color gamut than the current color space specification.

Raw is translated into English as raw material. To understand the RAW format, you first need to have a general understanding of the actual imaging process of a digital camera. When we press the shutter, the light passes through the lens onto the camera's image sensor, which converts it into an electronic signal that forms the image data.

In short, these electronic signals are the main raw materials that make up RAW files. The key to distinguishing the RAW format from the JPEG format is the processing of these electronic signals after they have been collected. A RAW file consists of the raw electronic signal recorded by the sensor and the associated basic information, which is saved directly to the memory card without any compression or processing.

Before the JPEG file is saved to the memory card, the raw electronic signal recorded by the sensor has been processed by the camera's internal processor according to the settings we have selected, such as white balance, ** style, etc. The processing result is converted to JPEG format and then written to the memory card. In other words, no matter which format you use to shoot the camera, you need to capture the raw data, and we decided to hand it over to the camera for processing as JP

The processing result is converted to JPEG format and then written to the memory card. In other words, no matter which format you use to shoot the camera, you need to capture the raw data, and we decide whether to give it to the camera to be processed in JPEG format or save it in RAW format and we will handle it ourselves.

I'm sure many readers have tried to shoot in RAW format. The JPEG format is the default choice for most of the cameras in our hands, and although it is very convenient, it means that we unknowingly lose a lot of image details, which are preserved when shooting in RAW format. Unfortunately, many readers have to face some bigger problems after choosing the RAW format.

RAW files are very large, and not all post-processing software can open them directly. Camera manufacturers are reluctant to choose the same format to save the camera's original image information, which is really nerve-wracking and brings us a lot of inconvenience. But once we solve these problems and get used to shooting and processing in RAW format, we will find that the actual situation is not as painful as we thought at the beginning, and your photography level will enter a new level in one fell swoop.

We'll start from scratch.

With the RAW format, we were also able to change the white balance settings at will** after shooting. Although we can also use the color balance function to influence the ** color of JPEG images, it is really pediatric compared to the adjustment results of RAW in Adobe Camera RAW, and the processing process will also destroy the original image information of the file.

TIFF is a ** format, that is, tag image file format (abbreviated as TIFF), and JPEG is the biggest difference, TIFF supports high-bit data, that is, 16-bit and 24-bit data. JPEG, on the other hand, can only support standard 8-bit bits. TIFF's ** allows for finer picture quality, and of course the larger size.

RAW is not a ** format, but the raw pixel data output by the camera, and the RAW format and file extension of each company are different. RAW can be thought of as the raw material produced by the camera and requires further processing to produce**. RAW supports high-level data, usually 12-bit data, which is much larger than JPEG 8-bit data, so RAW contains more information than JPEG, so for high-quality ** output, it is generally chosen to adjust the RAW before output.

RAW can be adjusted by respecifying white balance, adjusting brightness by a large margin, or adjusting HSL (hue, saturation, brightness) for a single color channel. There is more room for manoeuvre than adjusting JPEG.

The RAW format is a file that records the raw information of a digital camera's sensor, as well as some of the raw data generated by the camera's capture. RAW is an unprocessed and uncompressed format that can be conceptualized as "raw image encoded data" or more figuratively referred to as "digital negatives".

The JPEG format is a compressed image file. The shooting has been adjusted inside the camera, such as color temperature, color balance, image sharpness and other information has been fixed, post-adjustment can only be carried out by professional graphics software, but the quality of the image will be lost.

The RAW format is generally recorded as 12-bit or 14-bit data, which means that each pixel that can be recorded has 4096 or 16384 different brightness levels, so it has a large capacity of tens of MB

The JPEG format is generally recorded as 8 bits of data, which means that each pixel that can be recorded has only 256 different brightness levels, which is much smaller than the RAW format.

Easy to use in other software. Many software can't handle RAW directly

RAW: called**full data,That is**all the parameters of the camera when shooting, including aperture, shutter, sensitivity, white balance, etc., this storage method is convenient for the later modification of **, the disadvantage is that each camera manufacturer has different ways to protect raw data for its own data, and the amount of data is very large, and the storage time is relatively long when shooting, and continuous shooting can not be used, it is recommended to buy a high-speed card storage.

TIFF: is a file format that is mainly used to store images including ** and art art. It was originally created by.

Aldus worked with Microsoft to develop for PostScript printing. This format used to be mainly used for multi-platform data interaction, and it was very common to use it in desktop printing and drawing software.

The difference is that the RAW format is used by the camera manufacturer to store all the data when the camera takes pictures, while TIFF is used for data interaction between different platforms. It is recommended for post-data processing, it is better to use raw, you can adjust the **color level, white balance and other parameters.

RAW file is a truthful record of the original data of each pixel when the digital camera sensor converts the optical signal into an electrical signal, it only includes aperture, shutter, focal length, sensitivity and other data, without any processing inside the camera, and is not compressed, it is an original file. Only after data processing, a series of parameters such as contrast dynamic range, white balance and color temperature data, chromatic aberration signal, color saturation can be converted into visible images. Therefore, the **company must adjust its parameters to make it a TIFF or JPEG image file to make**.

Since the RAW file saves complete data for the image, it reserves a lot of space for the photographer's creation, and the photographer can fully adjust and compensate for the contrast, color space, sharpness, and saturation of the image through post-trimming, so as to improve the image quality and achieve the most satisfactory effect, which is not directly related to the size of the final expansion. For beginners who are not familiar with computer image processing, it may be difficult to master for a while because there are many links that require subjective judgment operations, so it is not as convenient as shooting and storing directly in JPEG format.
