It is unlikely and probably impossible to create a Canon CR2 digital image from a .tif picture source. Digital RAW photographs are recorded by digital cameras with all the additional setting and metadata and cannot be created with just a software. This conversion is usually done the other way.
This conversion entry was verified by us and conversion was flagged as wrong or not possible.
Usually this happens when the conversion would try to convert different types of data between each other, such as audio to image, or it is not possible because incompatibility between programs, caused by closed file formats, very limited support etc.
If you find entry that you feel is flagged as bad wrongly, please tell us in the discussion below with as much as information as possible so we can fix it.
