RawDigger is a useful tool for examining how the relative per-channel underexposure depends on the color of light. If the shadows look blotchy, colorless, or details in shadows are poorly resolved you will be able to determine how much they are underexposed and set Underexposure (UE) indicator in RawDigger accordingly.

RawDigger helps determining the raw level at which the overexposure “blinkies” start on the camera LCD and to know how much headroom is still available after the blinkies start showing.

That is, RawDigger lets you establish the headroom in highlights and obtain optimal exposures.įor ETTR practitioners, RawDigger makes it very simple to compare raw histogram to in-camera histogram and account for the difference, making the exposures as much “to the right” as possible. RawDigger allows determining how exposure meter is calibrated and what raw level corresponds to the midpoint of in-camera histogram. Overexposure (OE) indicator will show you exactly what areas of the shot are blown out and in which color channel(s) it happened (best if used in channel view). RawDigger displays the real histogram of the raw data, which greatly differs from the in-camera histogram and histograms presented by most of the raw converters. Support for new cameras is usually implemented within few weeks after raw samples become available. RawDigger supports nearly all cameras that have raw capability. Instead, it allows you to see the data that will be used by raw convertors. RawDigger doesn’t alter the raw data in any way. In essence, it is a microscope of sorts that lets you drill down into raw data.

So I just export a raw composite image and play with sliders to get nice tints to go with the almost black skies and very white clouds and foliage.Top Software Keywords Show more Show lessĪ tool to visualize and examine pure raw data as the camera has recorded it. Going one step further, if I were to put a 720nm IR pass filter on the lens then the converted image will look horrible the standard for non-Foveon cameras is to do channel-swapping in post but that doesn't work for a Foveon image. Here's another play with FastStone's color, hue and saturation sliders, just for grins: Non-reflective stuff like brickwork and anything shaded tends to look roughly 'OK'. Intense sky and red or red-orange foliage. The colors in my second image are what most full-spectrum shooter seem to favor. So with a full-spectrum, meaning 300-1100nm, image the final image colors can be anything you want them to be. Mainly due to the IR exciting the Foveon layers and a bit due to near UV exciting mainly the top layer. The moment you take the IR blocking filter out of the camera all colors become false. Is the second scene a little too red now? I'm looking at the sky colour.

Perhaps a pace to the right in the first shot? I had another version with a much bluer sky and yellow leaves but this is a little more 'conventional' for full-spectrum work.īoth shots were hand-held with the Sigma 18-200mm Mk II (not the latest 'C' model).Ĭomments are welcome. Processed in RawDigger - exported as RGB TIFF - seriously messed with in FastStone Viewer to enhance that heavy red cast. The tree is about 30 ft tall but the property is so overgrown that it's not possible to shoot the classic dead-tree-in-a-big-field-or-desert composition.

Once it had full sun on it against dark storm clouds - wow - but the moment was fleeting and cameras were nowhere near :-( This tree is always well-lit and catches my eye whenever I walk down the driveway. The Sigma SD1M 'Standard' color mode tends to give cyan skies and their 'Foveon Classic Blue' color mode is way over the top in blueness. Like the Monty Python parrot, this one is definitely dead: Continuing the theme of afflicted trees and Andre's 'denuded' series:
