When reproducing images on canvas media there is a lot of freedom - choice of media, choice of printers, finish and frame options. I would like to concentrate today how to make sure we can get best canvas prints from your photos at the very early stages. Some of the options discussed may be available to the owners of DSLR cameras only, some will apply to any digital cameras. With DSLR's it is crucial to choose shooting your images in RAW firmat. This format is actually free from any colour gamut cuts that are imposed by any colour space. We see very often that even after RAW files have been processed they are actually given sRGB colour space - which isn't going to contain all colours captured. Similarily Adobe RGB 1998 can also clip some colours but is much wider. It is much better to use this space - our goal in mind is to keep as many colour tones as possible. That allows to keep all smooth gradients and wide gamut of colours. There are some colours that will suffer more from assigning sRGB profile than others, but generally it will improve most pictures and certainly will not cause any colour loss in comparison to sRGB. We do also use Pro Photo RGB space which has a masive gamut but it only makes sense to use it in conjunction with 16-bit processing and printing. We have printed some images for professional customers using 16-bit workflow with good results. The improvement is probably more visible on paper substrates rather than canvas printing as canvas media texture makes some fine details to be lost anyway. It doesn't make much of a difference when printing on canvas. And as the reason is canvas texture there is no point in using 16-bit workflows for canvas prints ever.
Getting back to the subject of camera settings - please make sure to always use best quality settings available - it will pay off in the future. Not only when you decide to print it on canvas but it also allows to zoom in to the photo - and maybe choose different cropping if necessary. Processing RAW files does takes a bit of practice - but also gives all the control to us - it basically captures the data as gathered by camera sensor. If you use jpg format - automated algorithims will remove most of the data and slash most of it only leaving very generic reprsentation of them. The worst part is that there is no going back - the data is lost forever. With the RAW we can make many different versions of the image and only save it with some loosles compresion options like .tiff or even .psd.
