as far as the low contrast - might be my attempts at pp or the effect of trying to photograph through the windows of the enclosure or it could be you are right
Well, since you raised the example, to you, a picture taker, the window is an unwanted piece of glass sitting between the subject and your $1500 multicoated lens and $1000 camera's sensor, affecting the image quality.
Isn't that what a screw-in is?
I own *many* ND and polarizing filters, teleconverters and a magnifying diopter, but I use them all judiciously. The 1.4 HD TC is a superb one that cost me hundreds of dollars but I'll still try to get the shot without it. In a zoo, great, out in the wild, I have no choice, the distances are greater and I need to man up and take the hit quality wise.
BTW, if you are shooting through glass, push the hood right up to it, and if possible hang your sweater around it, to minimize the glare.
