You can do the same thing in two steps by switching to a default ISO noise profile and tweeking the exposure slider. So I was stuck with oversized tifs, 7 images only in the 128MB memory cards that were considered huge storage back when I bought the camera.įrom the history pane, I played around with the noise reduction before I did any sharpening. Why? There is a signal averaging step in the calculations which degrades the low signal results when making this type of comparison.Īs for the TIF file-whatever version of RT I was using 3 years ago didn't do jpgs. My 3020Z has low noise highlights coupled with high noise shadows with about twice the noise of a similar RGB camera. He also ignored me or didn't understand me when I pointed out some of the technical reasons his big print didn't prove anything.ģ-The biggest and most not technical reason was that in normally printed, real world images blue sky doesn't need noise reduction. I remember one salesman holding up a 30in print of mostly blue sky to promote the noise figure of the camera his store was pushing that month. For those I'm going to have to use a different camera.Ģ-The blue sky noise is half of what one would expect using a RGB demosaicing filter. This is an excellent starting point for B&W images and a no-go for any false color IR images. Without any post processing it loads up with a perfect 'white balance.' This is caused by the camera's unusual sensor, one that uses a yellow, cyan, magenta demosaicing filter instead of the standard Bayer red, green, blue filter.ĭuring the camera's internal calculations to create an RGB image that can be displayed on normal monitors several things happen.ġ-The camera creates identical RGB channels from the internal IR RAW values. And yes, the much simpler RT workflow that produced these little masterpieces is worth blogging and bragging about.Īlthough I didn't highlight it, up at the top you can see this is a tif file. I was about to jump into the discussion and shout out all the ways RawTherapee works better, when I thought it wouldn't hurt to process an IR image to check that I knew what I was taking about.Īfter searching around in my backup folders- I had vaguely remembered taking a infrared set three or four years ago-I found these images. The thread that caught my eye was on Lightroom, infrared images and some over complicated problems you face using that editor. So I was more interested in seeing how flickr's new interface worked when I happened to visit the discussion area in flickr's Digital Infrared group three day ago. Learning the ins and outs of IR photography wasn't going to teach me anything I didn't already know. Rather it because I spent multiple years of my working life designing, building and servicing unusual and very expensive infrared instruments. Not because I don't enjoy looking at them. Grayscale JPEG and TIFF images are now supported.I've never been that wild about taking infrared images. They support the same ranges as the Navigator. The Lockable Color Picker allows you to place multiple sample points over the preview to measure colors and see them change in real time as you manipulate the image. The Navigator can show RGB, HSV and L*a*b* values in a range of 0-255, 0-1 or %. The Contrast by Detail Levels tool received the "Process Locate Before/After Black-and-White" option. Queue processing will stop if an error is encountered while saving, e.g. New exposure tone curve modes "Luminance" and "Perceptual". Post-resize sharpening, to give your photos that subtle crispness after resizing them.ĭual-illuminant DCP support with curves, base tables, look tables and baseline exposure. The curve pipette allows you to pick the right point of a curve by clicking in the preview, and input/output values so that you can set the desired output value for a given input value. The "Inspect" tab in the File Browser lets you see a 100% preview of the image whose thumbnail your mouse cursor hovers over, which is either the largest JPEG image embedded in the raw file or the image itself when hovering over non-raw images.
