Hi

Just started with Qimage and I'm trying to print from a DNG file created in Lightroom which has had some adjustments made to it in LR, but Qimage seems to only want to preview and print the original unadjusted RAW image. Could someone point out where I'm going wrong ? (The original RAW is from a Nikon D3x NEF file)

I also tried to print a PSD file with layers and Qimage only picked up the bottom layer and ignored the rest. Does this mean I should flatten the image before printing ?

Thanks in advance

The DNG file has a "sidecar" file that is an Adobe exclusive.
In order to carry the adjustments you made, you would have to create a TIF or a JPG from the adjusted file.

As to the PSD, Qimage reads PSD files and prints them whether they are flattened or not.
Look at your PSD and see what is going on.
You are aware that PSD files must be saved with the Max Compatibility box checked.

Thanks for the reply, I'll convert to TIFF and print from that.

Does anyone know if DNG will be supported in the future as I was under the impression that DNG was open source ?

DNG is basically a raw format and Qimage Studio Edition does support and process/convert it, like most other raw formats.

DNG is not open source in the usual sense. My understanding is that it's an Adobe format which they would like all camera manufactures to use,  therefore the details of the format are in the public domain. Some cameras (Pentax) will produce their own raw format or DNG.
