I am trying to use a smartphone camera for image capture. I am using the Lightroom mobile app on my iPhone to be able to capture the images in DNG format.
To open the DNG files, I am using BioFormats in Fiji. Everything seems fine until I see in the Metadata window “Compression: JPEG”.
Can anyone let me know why there is compression shown here when the image is opened? This should still be an uncompressed DNG file…
I have opened the same image that was downloaded to my computer via iCloud instead of Lightroom and again opened it with BioFormats. In this case, the Metadata window shows “Compression: Uncompressed”. However, using this method I go from the 4032x3024 image from the Lightroom download method to 256x192 for the iCloud download method. Ideally, I would like to have the higher resolution Lightroom image that remains uncompressed.
I know that most people are probably not using smartphone cameras for their image capture, but here this is a major component of the project. Any advice on how to best combine smartphone image capture with transfer to Fiji and processing would be very helpful.
