By assigning a color profile to an image file, you insure that all of the pixels in the image file will fall inside the safe color space for that media. If your image file contains colors outside the capability of the printer/paper or monitor, weird things happen to the appearance of the image being viewed on that media. ![]() LED monitors are always improving the color capabilities to the point that the generic AdobeRGB color profile comes pretty close to describing the colors that a modern flat screen monitor can display. HP & Microsoft developed a generic colorspace and color profile (sRGB) that would be safe for all monitors of the time. CRT monitors could generate a smaller envelop of colors. Adobe generated a generic colorspace and color profile that encompasses MOST color printers and papers. However, printers exhibit a different color profile depending upon the paper and printer model being used to generate the print. (Color profile) ProPhotoRGB is used by Adobe because some computed pixels may fall outside of one of the smaller triangle envelopes. The different enveloping triangles represent the colors contained in the colorspace assigned for the file. The colored lozenge represents all of the colors that a typical human eye can perceive. This is a definition of the colors (that can be) found in the image. ![]() Not only do you save on local storage space, you have at ready the tools to create and send away the derivative specific to the desires purpose and media destination. As long as you have your original file and your Lightroom Adjustments, you can as NEEDED, create the export for the purpose that you have at the time. You don’t need to create a derivative (export) file at all until you need it. If you want to email a copy to a friend, then you might be limited in the size of the attachment (25MB or less).Īs you can see, there is no “one size fits all” set of settings. Some won’t take a TIFF file and Some want you to specify a generic color profile. If you need to use a third party print facility, them you will need a file in the format they specify. If you want to print the file, you will need to know the color profile of the printer and paper to be used and save the file as such. This will probably generate a huge file likely larger than the original lossless compressed RAW file and overkill if the original was a lossy 8 bit JPEG. However you probably want it saved with a large Gamut Color profile such as the generic AdobeRGB. ![]() In that case an uncompressed 16 bit TIFF makes the best archive file.
