Work with raw images begins with their converting to some readable format without changing any brightness values. Output of the program with default settings and jpg output of the camera are not identical in brightness, although very similar. Output of the program (as well as jpg output of the camera) is cropped by 8 pixels on each side and has size 4592x3056 px, while original size (preserved by conversion tools like dcraw) is 4608x3072 px Its successor, Imaging Edge, works better, but only on 64-bit systems.īesides the bugs, following details are notable: In response to my report of these bugs, I was told that the program is no more supported by the manufacturer. So, very small details are always spoiled (which would not be the case if noise is removed by frame averaging without noise reduction). Noise reduction is implemented even when turned off. Sometimes output image contains thin and hardly notable line looking like some juncture, running vertically across the image's center To obtain 16-bit tifs, you should use batch conversion When converting a single file into tif, setting "16 bit" does not work: image becomes 8-bit in any case. Noteworthy issues with Sony Image Data ConverterĪs of January 2018, the program has some notable bugs: Transformation of colors into standard color space Reading them in Matlab, where all the following work will go on Īccounting for darkness and saturation levels Such approach gives access to linear brightness values, and, hence, is compatible with operations like flat-field correction.ĭecoding raw (.ARW) files into 16-bit. This page concerns converting raw files with the help of scripts for Matlab. The same applies to conversion with self-made scripts, but they are, at least, fully controllable and changeable.
More mighty and transparent tools are also available in Internet, but they need characteristics of the particular camera. In addition, such programs create beauty at the cost of truth. But they do not give linear brightness, which is essential in any serious work, their algorithm is unknown and, moreover, the first of them is obviously half-baked. It's reasonable to assume that these tools are adjusted for Sony cameras and know all their characteristics.

Manufacturer of the camera provides software for RAW converting: Image Data Converter and Imaging Edge. Majority of these tips is applicable to other cameras as well. Here are some notes about imaging with Sony NEX-5 camera and converting its raw files into ready images.
