RawTherapee non-destruction testing my patience

Having spent the last few hours editing images with RawTherapee, I came upon an image that I felt needed cropping. I opened the Crop Tool, drew my ‘box’, saved the image, then re-opened it to find that the image had not really changed. The entire image was still visible with my crop box shown. I looked online for an answer as to why this was, and the response told me that saving an image in RT does not produce a viewable image because of RT’s non-destructive nature. That also means that, in order for any of the edits to the many images I’ve edited, I will have to re-open each of them and export them (I presume to some new, slightly altered filename), or perhaps use ‘save as’ with the same name since my original files are Sony ARW raw files, and I am saving the edited images as tifs.

I suppose I cannot snort too much steam at the RT application. More upfront investigation on my part would have disclosed this operational feature of RT, but it is a totally new experience in my case. The source files had an ARW file extension, and I was saving as TIF, so why would RT “protect” me from destruction when I was not overwriting the original file. I would have thought changing the file extension would signal to RT that it was not overighting the original file. Will saving to a different filename overcome this non-destructive issue?

I am liking RT very much, but I little “niggles” like this in software irritate me. It’s not the end of the world, of course. I will backtrack and open/extract each of my edited images to overcome this little problem. Saving an ARW file to a TIF should not be construed as overwriting, IMHO. Am I missing something?

Thanks in advance for any replies.

Perhaps having a read of the getting started page will help: Getting Started - RawPedia

Your complaint indicates that you don’t realize an edit is not done until it is exported. That is the way with all good editors. It is a bad editor that overwrites the original file without warning you of such an action. Because you started with a RAW it can not be overwritten as it is a RAW file without processing. If you had open the cameras JPG output some programs will allow you to overwrite that file. Not sure about RT.

So yes you are missing something and my response was not meant to sound rude or condescending. Do an export of the edit you are happy with. Then in the future years you can return to that RAW file and start over with better tools, more experience or a different output required. That is the advantage on non-destructive edits.

I think this is just the preview and the way that RT shows it…so you see your crop box on the whole image…there is a preview mode to switch the preview to the actual cropped area and that should match the file that you saved so I don’t think wrt the cropping you will have any issues you just need the right preview???

You are right. I am not clear exactly what you are seeing though. You understand that the ARW will not be modified. You expect the TIF to be cropped. But the way you expect it to work is also exactly how RawTherape works. Is that not what you are seeing? The TIF is cropped, right?
