Add Missing Color Profiles in Box Preview
Image capture devices (cameras, document scanners, etc.) and image display devices (computer monitors, cell phone screens, printers, and so forth) all have different natural color and tone characteristics. One camera may be more sensitive to reds, while another camera will react more to blues. Some LCD displays may naturally be brighter or darker than others. Depending on which two device, we are comparing, these differences may be subtle, or very large and obvious.
Color profiles provide a means by which an output or display device can make accommodations for these differences, meaning that your image can appear more or less the same on different screens. All modern web browsers support the most common color profiles types (sRGB is used most frequently on the web), and leverage the profile data included in jpegs and pngs to properly render the image.
Box currently drops the color profile data from the preview jpegs that are generated for uploaded images. As a result, the web browser has no knowledge of the unique color characteristics of the device that was used to capture the image you are trying to preview, which leads to unpredictable color shifts that may be mild to severe, depending the specifics of the capture and display devices.
This problem makes Box Preview a nonstarter for photographers and other image professionals. The solution is simple: Box Preview should retain the color profile data for sRGB images, and be able to translate other common profile types (at least Adobe RGB and ProPhoto RGB) to sRGB when preview jpegs are generated.
