RAW (Raw Image Data) is the most popular file format for uncompressed and unprocessed images used by digital cameras. RAW file stores the image captured with camera’s image sensor directly, without any compression used.
After converting the file to the new format, you will be able to use other programs to support it. Keep in mind, however, that the ICB file after converting to RAW may differ slightly from the original. The most important information should be kept, but if you want the file after conversion from ICB to RAW to be the same, you have to do this carefully and choose the proper application from the list below.
There is no guarantee, of course, that the conversion will come up to all your expectations, but it will certainly help you. If, after all, the effect of converting ICB to RAW does not meet your expectations, you can simply try to find on the Internet a different version of your file in ICB format, properly converted to a RAW file by someone else. If this fails, use the information provided in the further part of the website.
Unfortunately, if after performing the two previously described steps (trying to find your ICB file converted by someone else, and the attempt to convert it to RAW on your own) you still have a problem with your file, then there are only a few solutions left. You can once again try to find and install an application that can open the ICB file in its original format (without conversion to RAW file). Such a solution will be difficult to implement, but it certainly will give the best result.
