![]() Moreover, in the professional printing phase (large posters and in CMYK color space), the JPG format risks to present in correspondence of high chromatic contrast areas artifacts due to the compression process TIF format (16 bit) allows to have an output file with much more important dynamics, and this is particularly interesting if you want to highlight image sectors that have dark or light areas. RAW formats generally use a compression technology that does not alter the pixel value ( lossless), without data loss and quality – JPG images are usually saved using a compression format that corresponds to a certain loss in quality. – The standardized steps performed by the camera, such as sharpening and noise reduction, are avoided to leave the operator free to optimize these parameters Since all image treatments (such as gamma correction, demosaicing, white balance, brightness, contrast…) used to generate pixel values are done in one pass on the basic data, the resulting pixel values will be more accurate and will show less of the posterization phenomenon (defined as an effect applied to an image which it is compressed, reducing the number of color levels, increasing contrast, but decreasing the nuances) – It has many more shades of colors (4096 to 16384) than the 256 shades of a compressed 8-bit JPG The RAW format has considerable advantages over the JPG format, such as: Of course, this requires an additional step before importing the image set into our stacking software. Exporting in RAW format allows to get access equally to images that are already pre-processed by the camera software, but these settings are completely manageable, editable, and can be improved during the post-processing. The parameters are calculated automatically or defined by the photographer BEFORE the image is captured, so it is no longer possible to make profound changes on these values. Using the JPG format means that the image we receive has already undergone a process (total or partial) of color balance, saturation, contrast, and sharpness. JPG? I will partly summarize what is written on Wikipedia about the benefits of using the RAW format in photography. Why complicate your life using a RAW format and not working with the lighter and easier. DGN format is possible only if you have installed the Pro license in Helicon Focus. TIFF (8 bit or 16 bit), while Zerene Stacker only. ![]() The format exported of the compiled images is slightly different in the two software, with Helicon Focus able to export files in. TIF, before importing in Zerene Stacker the series of images to be compiled. ![]() JPG format), you must convert all frames from RAW to. TIF format is that not all cameras allow you to save images directly in this format, so if you want to keep intact the 16-bit encoding (and not use the. CR3 for Canon…), while Zerene Stacker only allows you to import. DNG (Digital Negative, a format developed by Adobe, open) and many RAW formats created by the various manufacturers of the most popular cameras (.
