The bottom line is that I enjoy the paintings in the Gallery, and can then enjoy them again in the comfort of my home, and even see things later that I missed in the Gallery, especially if I enlarge the image.
Absolutely! This is why I always feel so disappointed whenever an art gallery forbids all photography. I can understand a prohibition on the use of flash, because that can disturb other viewers. I can understand a prohibition on tripods, because they can get in the way of other patrons, possibly even tripping them up and causing an injury. I can understand the annoyance to other patrons, of people standing in front of paintings to have their photo taken in order to demonstrate that they were there.
So here's the solution for all galleries.
(1) Flash photography and tripods not allowed under any circumstances.
(2) Inconsiderate behaviour such as obstructing the paintings in order to have one's photo taken in front of them, is not allowed.
I was surprised a few years ago when visiting Russia for the first time, that I was allowed to take photos (without flash) of any of the very famous paintings in places like the Hermitage and the Russian Museum in St Petersburg. All I had to do was pay an additional small fee for the privilege. I thought that was a very civilised approach.
Occasionally when I wanted to photograph a particular painting, there was someone standing right in front of it, inspecting the brush strokes. Not a major problem. He/she would soon move on. A greater problem sometimes was the reflected light from the glossy and shiny oil in certain parts of a painting. In order to avoid them, one would sometimes have to photograph the painting at an angle, which later would involve the use of Free Transform and Distort in Photoshop in order to correct the perspective.
Attached is such a painting. If I hadn't been able to photograph this painting I would probably have forgotten its name and the name of the painter, and would not later have searched on the internet for the wonderful story of Phryne, the subject of this painting.
To cut a long story short, Phryne was a beautiful model who lived during the times of ancient Greece. She had a tendency to flaunt her beauty at religious festivals. When she was eventually accused of profanity towards the Gods, she was in very serious trouble, but fortunately her lover was a lawyer. As the trial proceeded, in front of a group of elderly, all-male judges, it seemed clear to her defense lawyer that all was not going well. The verdict could be disastrous for his client/lover. So in a desperate attempt and 'last resort measure' to save the day, he brought Phryne directly in front of the judges, just a few feet away (although I can't be sure about this because I wasn't there), and tore open her robe to reveal her beautiful breasts, whilst simultaneously imploring the judges to consider how someone possessing such beauty could ever be guilty of profaning the Gods.
The judges immediately came to their senses and acquitted Phryne of any religious sacrilege.
