Good day to all, I obtained an array of 512*512 U32 data from the photomultiplier using the analog input of DAQ board. My question is how to convert this 32-bit matrix to 8 bit monochrome image for display. I tried the method in this post to convert array to grayscale image https://decibel.ni.com/content/docs/DOC-4155 but the result looks like a contour rather than real image. I guess it is because their input to Flatten Pixmap is 8 bit, but mine is 32 bit. Do I need to do gamma correction to scale my data? But how? I attached the original image, which is a particle.I also attached my labview code and the processed image. Thanks!

Simple scaling for maximum contrast.

Then you'll probably need to do you own custom conversion then that increases the difference between the brightest and the darkest.You could just make 4294963840 the zero and 4293967276 the max and scale down to 0-255
