One must remember it does make a difference which device and Windows one is using when taking photographs. Photographs that are what may be deemed to look perfect and with correct light (whatever that is) may look terrible if someone is viewing them on say a Windows 10 when they were taken with Windows 7 or 8. Not everyone has the latest phones with all these features, nor should we feel pressured to have them to suit someone who thinks our photographs in their eyes aren't perfect.
Perhaps they should try experience life as a Visually impaired person and then they may appreciate that life is different for everyone of us, and for good reasons.
The world would be very boring if we were all the same.
As an aside, rather then permently remove the said photos "in question" maybe try change the lighting on the originals and see if that helps.
All the best & great topic to raise.
PS Take a look at my Hens, Gotland sheep, birds & trees photo at Cornwall Park on my Listing & whilst I know it's a little dark it's still been a favourite amongst recent guests and others I've shown to.
