Hi, I am using this on my Sasmsung S5 phone and I find out my camera don't make good focus on photo so then picture of cpectrum is blur and not sharp so then I can't get good photo. For example:
Is there any workaround to set focus manually so then photos would be sharp and I get better spectrum?
I haven't found a technique that worked for all phones but some apps let you fix infinity focus.
