This way, the jpeg is made in camera, via processing steps tuned by the camera engineers to match the camera. I’d rather shoot a good set of jpegs, stack them, and save the output as a TIFF file. If so, any benefits offered by raw formats are lost. If I understand this discussion, Helicon can do a quick and dirty conversion from some raw formats, based on a set of default assumptions. We should be careful what we ask for, as we may get it-and in so doing, sacrifice things that might offer more benefit.ĭitto for having Zerene Stacker muck around with raw files. This item would rate very low on my priority list. Whenever something is moved forward in the queue, other things have to move backward. Importantly, processing resources are not the only issue from what I know of software development, support/enhancement chores always need to be prioritized. Since I have wide-gamut color representation when applying curves, saturation, and other modifications appropriate to pixel editing, why would I need it during stacking? My colors might look less vivid during stacking: No problem-I take all my stacks to Photoshop, where I apply a curves adjustment and other modifications. If wide-gamut color display were available in ZS, and turning it off would shave a couple of minutes off a thousand-image stack, I would turn it off. Since ZS preserves the color profile of the input images in the stacked output image, I wouldn’t describe ZS as being “not color managed.” I'd say that Zerene Stacker takes a highly efficient approach to color management, in preserving color profiles without wasting resources on fancy display. If I'm wrong about that judgment, then more information and discussion would be most appreciated.Īs a Zerene Stacker user, I give the current approach a thumbs up. As a result (it seems to me), the lack of color management during display has pretty small effect on its operation. It is not designed as a viewing tool except as needed to support retouching, and it has no capabilities to adjust contrast, brightness, or color balance.

(Also, Adobe is steadily in the process of converting Photoshop to a completely RAW domain. There are also many moves afoot to standardise the file system for RAW, including those by Adobe. Of course, you would need a RAW converter embedded in ZS to be able to render the images for editing, but I was thinking there would be efficiencies to keep the files in the RAW domain. My point was directed at the time and CPU efficiency of converting just one RAW final (the final one) and managing smaller file sizes. That's why the first step in digital photo processing is to carefully convert the Bayer matrix pattern that the camera actually saw, into a traditional RGB or LAB representation in which the same type of information is stored at each pixel position. Information in Bayer filter format is essentially useless for most photographic purposes. Unfortunately, what the camera actually sees is typically a mosaic of RGBG, GRGB, or RGGB values, one color per pixel position, courtesy the Bayer filter that sits in front of the sensor to allow color information to be captured. Second, the advantages of raw formats are due entirely to their being a faithful representation of what the camera sensor actually saw. Several major camera manufacturers, including Nikon, Canon and Sony, encrypt portions of the file in an attempt to prevent third-party tools from accessing them. Often they also change the format from one camera model to the next. Different manufacturers use their own proprietary and typically undocumented formats, which are collectively known as raw format. There is no single raw format formats can be similar or radically different. Providing a detailed and concise description of the content of raw files is highly problematic.
