Essentially yes, thumbnails. Whatever you call the images that appear in the grid view. I am working with DNG images that come off either a Yi M1 Micro Four Thirds camera, or from the camera that I am developing which also produces DNGs. In both cases there are embedded thumbnails in the images. I believe I have seen the same phenomena with CR2 files from 50D, but I would have to double check to be sure.
I can’t speak about JPEGs because I have never used Nitro with them lol
This is images fresh from the microSD and placed in a directory. I then open nitro and point it at the directory and work from there. The thumbnails look like a very low resolution image that has been blown up to the size of the thumbnail, if I double click it then it opens and is scaled up further.
If I wait then eventually the image will be processed/re-rendered/whatever the correct term is, and if I double click it then I will see the full sized image. If I hit escape to close it then that thumbnail (and only that thumbnail) will be updated to be correct.
Does that make more sense?
PS: It is a shame there is no way to upload images here so I could show you without the extra step of going to an image hosting service
