I have a camera a QooCam 8K to make 360 photos which I use for real-estate QooCamStudio is the Stiching programm. It only accepts images with a resolution of 3840 x 7680
I use HDR bracketing. It makes 3 photos (DNG) all in 3840 x 7680 at around 55MB each. My plan is to HDR merge them in Lightroom, then export them as JPEG and then sometimes the resolution is a little bit off 3821x7641. Is it possible that is sticks with the 3840 x 7680 resolution. The QooCamStudio doens't accept the 3821 x 7641 resolution
I was able to resolve this issue by not aligning the images. When the HDR Merge Preview dialogue Box opens, untick the "Align Images" checkbox in the options section. This will retain resolution so you can render in Qoocam Studio.
