Question

[jiangqi-1]

I have found that there is such a piece of content in the code：
num_ = int(fname[:-4].split('')[0])
den = int(fname[:-4].split('')[-1])
exposure_times.append(num / den_)
So do I need to Include the ’exposure time information‘ in the image name？How to name the LDR image ？ May I ask if
there is any example？
