![]() In theory it seems like you could get amazing dynamic range/highlight recovery from a Foveon IR shot. With RawDigger's RGB rendering, the exported file is ready to go, IMHO Standard IR advice is to open the file and then do lots of channel swapping and other stuff. No horrible purple mess, unlike SPP!įor the purists, here's the red channel exported from RawDigger and tarted up in FastStone Viewer, because RawTherapee won't open RawDigger's monochrome 16-bit TIFF exports ![]() Shot was exported from RawDigger as an RGB-rendered TIFF and processed in RawTherapee. The AF seemed to work OK but, of course the LCD previews were not real helpful having been subjected to the camera's idea of a sRGB JPEG (not noted for high quality on the SD14). Went out to the street and took a few shots. It also helps to have a hot-shoe OVF - because not much can be seen through the built-in viewfinder for some strange reason: ![]() As I take more and more shots with the m4/3 these days, I've taken the dust cover out of the SD14, put the big fat 24-60mm f/2.8 EX DG zoom on it and plunked a Marumi 700nm IR-pass filter on the lens. I myself prefer a bit of tint in IR shots. * RawDigger helps determine the idiosyncrasies of both camera and raw convertor by providing a true view into the raw data and comparing it to the results obtained through raw conversion.Theoretically, IR has no color and some purists do pooh-pooh anything not strictly B&W. * RawDigger can be used to check the amount of vignetting caused by the lens and the sensor. * Landscape photographers may want to use RawDigger to determine the effect of the filters on the lens, to check neutrality of polarizing and neutral density filters and, possibly, to select color correction and color compensation filters to use in different light. * For studio photography RawDigger helps establishing the proper light filtration to achieve the cleanest possible shadows on the shots. * RawDigger is more precise than any exposure meter for the purpose of evaluation of the uniformity of fill light and reproduction light setups (in terms of the evenness of both color balance and luminosity across the background). * 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. * For 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. That is, RawDigger lets you establish the headroom in highlights and obtain optimal exposures. * 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. 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. RawDigger is a tool to visualize and examine pure raw data as the camera has recorded it.
