Are the effects really being applied, or are they just showing up in the preview image of the application you use? For example, I can apply in-camera effects to my RAW images, and these effects will appear in my RAW editing software (Adobe Bridge & Camera Raw) as a preview image. Once opened for editing though, the edit disappears. Have you tried opening ...

In the iOS 10.0 release notes, there are two mentions of RAW images: The new AVCapturePhotoOutput class provides a unified pipeline for all photography workflows, enabling more sophisticated control and monitoring of the entire capture process and including support for new features such as Live Photos and RAW format capture. You should transition to ...

It varies highly from camera to camera. Some designs do a minimum of processing on the image sensor itself, others do a little more. Those that do more do so mainly in the area of noise reduction either before or after sending the analog data to be converted to digital data. One method is the relative amplification of the signal from pixels masked for red, ...

Basically, a RAW file stores data directly from the sensor of your camera. Most DSLR are using what is called a Bayer filter (https://en.wikipedia.org/wiki/Bayer_filter) to retrieve information about color. Usually, for 4 "pixels" (sensitive elements), 2 are used to get information about green, 1 for red and 1 for blue. However, keep in mind that this sensor ...

A RAW file contains sensor data which is not affected by effects. To speed up preview though, nearly all RAW files store an embedded JPEG to which effects are usually applied to coincide with what the camera settings are. It also used images parameters, including color modes, WB and selectable tone curve as you can edit them in the E-M10. The tricky part is ...

I have a Nikon D3s, only take raw files from the camera, and keep active D-lighting on most of the time. The purpose of ADL is to avoid blowing highlights that are too small or off-target to be otherwise metered. This is a common problem with digital cameras, especially point and shoots. Imagine a scene where most of it is in open shadow, but someone off ...

Back in the 1980s, Craig Anderton wrote a book called Home Recording for Musicians in which he observed that a recording studio isn't a capturer of reality, it's a processor of reality. You should think of your camera the same way. The light making up an image enters the lens, which changes it, reaches the sensor, which changes it, is passed through ...

pixel has different meaning in spheres of display technology and sensor technology. pixel of RGB Bayer sensor is represented by only one number (roughly one colour) while pixel of most of RGB graphic displays is represented by three numbers. The number of pixels noted on cameras is not the number of dots divided by four - it is actual number of dots on the ...

I've got the same problem with my GX8 and wanted to have some kind of preview in Windows Explorer. I searched for hours and finally decided to try out and then buy FastPictureViewer Codec Pack. It's very fast, but the preview image is not 100% accurate (you can see that when zooming in).

The thing you've got to remember is that you never really see a "raw" file on your monitor when using an application that handles raw file editing and conversion. (Yes, there are ways to view linear, un-demosaiced luminance values on a monitor. Even then there needs to be some compression of dynamic range to fit 12-14 bits of dynamic range into 8 bits. But ...

Part of the problem here is that Canon is not consistent, and does not follow normal conventions, in their file name suffixes. The original Canon RAW file was .CRW (Canon Raw). This was changed to .CR2 (Canon Raw Version 2). Then the trouble starts. The CR2 format has been changed. You'd expect therefore to see a new suffix each time the file format ...
