#Shooting raw and fotofuse full#

I can still take images shot with a full color camera (a camera that still has the bayer mask) and play with the de-bayer pattern. The vast majority of cameras use the RGGB pattern (which means the first two pixels of the first row are 'Red' and 'Green' and the first two pixels of the second row are 'Green' and 'Blue'). The pattern is defined by the first two pixels of the first two rows (so really four pixels in all). If they do want to de-bayer the data, they can indicate which bayer pattern is used by the camera. but the end-user can decide if they want to de-mosaic (de-bayer) the RAW data.

So it turns out, there is software that can open many different types of RAW files (because there is a need for it). not a color image that needs to be de-bayered to read it. This means that a RAW file from such a camera is actually a monochrome image. To create a monochrome sensor, the camera vendor will take the 'color' chip, and remove the bayer mask. Nearly all sensors are full color sensors that use a bayer mask in front of the sensor. The problem is, nobody really makes true 'monochrome' sensors. But when doing this, you'd really want to use a monochrome sensor.

This involves using filters on the camera that only allow very specific wavelengths of light to pass through the filter. In astrophotography, there's a concept of 'narrowband' imaging. This is not very common in traditional photography, but I do it for astrophotography. It is actually possible to view RAW data without decoding anything. When I do this in Lightroom, changes such as 'picture style' are not applied (I've tested this by setting the 'monochrome' picture style.) It will be noted that the setting was active in the 'meta-data', but it would be up to the post processing software to read that meta-data setting and apply the effect. So far as I'm aware, no other camera setting will have any impact on the 'RAW' data itself.

But in reality, the sensor captures whatever light was available, then the shutter closes, then the camera applies 'gain' (amplification of the data) based on the ISO setting selected. It's easier to explain to new photographers that changing ISO changes the sensitivity because it behaves 'as if' it changed the sensitivity. There is no setting in a camera that changes the 'sensitivity' of the imaging sensor. ISO is an amplification of the data which is not applied until *after* the camera shutter closes. But the RAW file will record whatever actually reached the sensor. If you change the f-stop or shutter speed, then you change what the camera 'saw' by changing how much light reaches the sensor. the RAW data records what the digital sensor actually 'saw' during the exposure. ISO gain is always applied after the shutter closes but before saving the file.) without applying any tweaks (ohter than the ISO gain. The RAW file contains what the camera *actually* saw. it applies to things like white balance, hue, etc. Lightroom shows that preview as it processes the RAW data and as soon as it finishes processing the RAW, it switches from showing you the preview to showing you the RAW. Adobe Lightroom) you'll see it's a COLOR image (you might briefly see it as monochrome as the image is opened.) This happens becasue a RAW image saves a thumbnail 'preview' image as a JPEG embedded in the RAW and that preview image will be monochrome (or whatever picture style you set).

But you can change this in DPP and it'll show you the image as whatever style you set. so it applies the monochrome picture style in DPP. The RAW file actually contains all the color data, but since DPP is a Canon app, it respects the meta-data setting that tells it you used a monochrome picture style. If you open the image in Canon DPP you will also see it's a RAW image (but with some caveats). When you review the shot you just took, you'l see it's a monochrome image. set the picture style to 'monochrome' but save the images as RAW (.CR2). In another thread, I mentioned that if you want to see a really obvious exmaple of how this works.
