CanonPro 1 The camera can see the photos, but the computer can't recognize them.

Because you use the RAW format, which is a lossless format, you need software support to display it on your computer.

What is the RAW format?

Nowadays, many digital cameras can store not only JPEG and TIFF images, but also RAW images. In fact, RAW is not an image format, but an original record of the level when the CCD or CMOS of the camera converts the optical signal into an electrical signal. It is obtained by simply digitizing the image data without any processing inside the digital camera, that is, the electrical signal directly obtained by CCD and other photographic components. For example, for a 3-megapixel digital camera, a RAW file stores 3 million photosensitive data points. When we usually shoot JPEG format, the digital camera adds parameters such as white balance and saturation inside the digital camera on the basis of RAW format, and then generates image data and compresses it.

RAW data processing software attached to digital cameras can convert RAW data into common image data such as TIFF, and users can set parameters such as white balance, sharpness and contrast at will, so that users can create their favorite images. Processing RAW format image data is different from JPEG image because image data will not suffer from image quality deterioration.

How to get RAW format files?

You must have a camera that supports RAW format to create RAW format files. You need to save the camera in RAW format before shooting. In Adobe Bridge and Photoshop, you can only handle the digital cameras they support. You can view the list of supported cameras here.

Let's take a look at the general RAW processing workflow, as shown in the following figure:

Of course, this is only a work order under normal circumstances, and sometimes it has to be adjusted according to the actual situation. But in this process, as the soul of RAW processing flow-RAW converter, the use of RAW conversion software plays a vital role in the quality of the final film. Each manufacturer will develop different software to convert their own RAW format files, so the transplanted software will not be introduced here. Therefore, this paper only introduces and explains some mainstream RAW converters at present.

First of all, RAW conversion software can be divided into two categories as a whole:

▲ Linear conversion: only the work of color deduction, in which white balance setting or exposure correction may be used, but most of the work should be left to Photoshop. The representative of this kind of software is DCRAW.

▲ Function conversion: This kind of software can complete most of the operations and adjustments needed in the workflow, and almost achieve the desired effect after painting, just making some adjustments to Photoshop. Software such as Phase One C 1 Pro, Bibble Pro, Camera RAW for Photoshop, etc.

I. DCRAW

DCRAW is a command line RAW conversion software developed by Dave Coffin based on Linux platform, and it is also one of the few open source free software. Software updates are very fast and are supported by almost all models on the market. The current version 7.0 already supports Canon's 350D. The author claims that all or part of the following softwares use their algorithms to decode RAW: Adobe Photoshop, Bibble, BreezeBrowser, idea Lightbox, cPicture, dcRAW-X, Directory Opus Plugin, Thorsten Lemcke's dpMagicGraphicConverter, IrfanView, IRIS Image Processor for Astronomers, light box, Photo Companion, Photo Jockey, PhotoReviewer, PolyView, Power slook-II, RawDrop, RawView, SharpRaw of Duane DeSieno, SilverFast DCPro, ViewIt, Viewer n5, VueScan. For more details, please check here:. Net/~dcoffin/dcraw/, you can download its source code, modify it yourself, and recompile the raw converter that suits you best. For most users who use Windows system, don't worry, because someone compiled the software into an executive version of Windows, and optimized different CPUs.

Ask the master old fox:

The article mentions the problem of shooting RAW pictures. Can you understand it like this?
