Подскажите кто знает, через что можно корректно перегнать 204 .jpg файла с цветовым пространством Abode RGB 1998 в .jpg но с цветовым пространством SRGB если средствами фотошопа, можно ли как то автоматизировать процесс? что бы не приходилось каждый перегонять в ручную, или путём акшена ? или же есть сторонние программы для этого?
A majority of the image formats assume an sRGB colorspace (e.g. JPEG, PNG, etc.). A few support only linear RGB (e.g. EXR, DPX, CIN, HDR) or only linear GRAY (e.g. PGM). A few formats support CMYK. Then there is the occasional format that also supports LAB (that is CieLAB) (e.g. TIFF, PSD, JPG, JP2). To determine the colorspace of your image, use this command:
When processing an image, be aware of the colorspace. Many image processing algorithms assume a linear RGB colorspace. Although you may get satisfactory results processing in the sRGB colorspace, you may get improved results in linear RGB (essentially sRGB with the gamma function removed). For example,
As of IM 6.7.8-2 one can properly work in LAB colorspace whether or not Imagemagick is HDRI-enabled. Essentually the A and B channels are stored with a 50% gray bias, to allow it to handle the negatives required by the format.
convert lab.tif -resize 50% resize.jpg
Again, it may not make sense for some image processing operators to work directly in LAB space, but ImageMagick permits it and generally returns reasonable results.
Prior to IM 6.7.8-2, the A and B channels has a discontinuity, making them non-linear. As such to process such images, you needed to first convert the colorspace some other linear colorspace, before apply your processing operator. Afterward you can transform back to the LAB colorspace. For example,
