It was also the case for Claude Monet in later life. Failing eyesight affected his painting style.I have a theory that was brought up years later that Turner's impressionism was due to his sight. He certainly wore spectacles as I discovered some years ago at an exhibition of his work.
I think with Turner (as with any artist) you have to look at their early work to see where their later offerings were coming from. Even at an early age you can see a bold use of colour, innovative perspective and a willingness to employ unconventional techniques. See 'My Cats' by Joey Turner:Definitely faded, the natural indigo he used is affected. Rain, Steam, and Speed and the Fighting Temeraire both used quite a bit. A bit of colour rebalance wouldn't go amiss.
I'm slightly confused by the original post which mentions Photoshop (I'm assuming implied human) and also AI
In my uneducated opinion eyesight might be a minor factor but doesn't explain his style, he's purposefully painting what we'd now call an "artistic" rendering not trying to reproduce anything an observer may have seen, sunset in the East of the Fighting Temeraire as an obvious example isn't an eyesight issue
I hope you like my philosphical discussions. Like my photography they remain rooted in the past.

I think my point was what do we recognise as real any more ? All photography is moving into an area where everything is edited. Maybe reality becomes distorted and when we are faced with how things really are we can be disapponted.
Small, or far away?I removed one of the small cows at the bottom
Well ... the real thing is real, a photograph or a painting is a real photograph or painting.I think my point was what do we recognise as real any more ?
Ansel Adams regarded the photographic negative as "raw material" and spent far more time in the dark room than behind the camera and the vast majority of "serious" photos always have been edited. Editing now might be easier but the bar has also gone upAll photography is moving into an area where everything is edited
Sure it's not a Louis Wain painting - certainly resembles one only not as good.I think with Turner (as with any artist) you have to look at their early work to see where their later offerings were coming from.

As a doctor I consider this deplorable. I have heard of people being asked to photograph the backs of their heads and their throats in recent years Problem is that not everybody has the brains to think about the variables. I did take medical images and had some published (taken in the course of my work) but a certain amount of thought had to be put into photographing skin lesions etc. I worked with both slides and latterly digital. Some the things I saw were fascinating rarities but I am still trying to find somebody who wants my library of shots.
The initial query came from a friend. Her kid had a recurring rash on one arm. These days, doctor visits are cheaper and significantly faster when done online or even asynchronously over email. In this case, the doctor sent a private message over the hospital's online system. He wanted a photo of the rash.
This sounds simple enough. Take out the camera, hold out the arm, take a photo, and then upload it to the doctor. Right?
Here's the problem: Her camera kept automatically applying filters to make the picture look better. Visually, the arm clearly had a rash. But through the camera, the picture just showed regular skin. It was like one of those haunted house scenes where the mirror shows something different. The camera wasn't capturing reality.
TLR: No way to turn this off. Only solution was to use an old, dedicated camera.
All of my work with a camera above or below ground are never edited, I believe that my "snaps" stand by themselves.
