A 2 dogs standoff?

[New to photography]

Hopefully I have posted this in the right section this time! and hopefully it is the right size too! Just wondered if anyone had any thoughts on this picture? good or bad - I'm learning about all this so anything helps really. Sorry, I can't print up any the data - I don't understand how to do it - where to find info, etc... All l can say is I took it on my Canon E0S500D in sports mode with my telephoto lens: Tamron AF18-270mm - the lens has a UV filter on it - I have no idea what that's supposed to do but the guy in the shop said it was a good buy???? It cost £30, but I can't see any difference in the picture quality?? Anyway, enough waffling from me, here's the picture, please critique:

I like the composition well enough, but at this small size it is impossible to judge sharpness.

As a dog trainer, the interaction is interesting to me with the calming signals, etc, but that is a whole different topic.

Exif data records (among other things) your shutter speed, aperture, ISO, etc. A quick Google will give you plenty of info on what it is and how to access it.

One of the first things any new photographer should learn is "If you don't know what it is for, don't buy it."

UV filters were all the rage a while back but they are really unnecessary now.

The manufacturers would like us to believe that they protect the lens element, but there is really little advantage there. As for eliminating UV haze, they will in certain situations, but 99% of the time that can be done in post easier than putting the filter on.

The disadvantage is that they degrade image quality and can cause ghosting. Basically, any extra piece of glass between subject and sensor will cut image quality down.

Today, the only filters really worthy of occasional use are a polarizer and some graduated neutral density filters.

I agree with you totally, I have some really great shots of sunsets ruined by UV filters and their reflections. Although it degrades image quality, I'd rather have a bad shot than a broken lens. So either way I'm keeping my UV on. You can't always keep polarizers and ND filters on they're just for special purposes. It would be useful if manufacturers could offer the front elements of each lens to be replaceable at a low cost. Anyway back to the image. I do like the composition although the white part of your boxer's eye ruins the shot in my opinion. It would be much better if you could get both his eyes looking in one direction preferably to the direction of the boxer to the right. The exposures are great. BTW 30 pounds is too much for a UV I got mine for $5.

Thank you for your comments, so useful - you know I'd never even noticed the white of Ruby's eye until you pointed it out! how blind am I!

You got your filter for $5!!! I was robbed! Sorry, silly question now, but what are polarizers and ND filters?

[Jim Poor]

Polarisers reduce reflections because they are polarized just like sunglasses.

ND = Neutral density. The reduce the amount of light that comes through the lens. The are great when you are trying to get blurred water when the sun is too bright for a slow shutter speed.

Graduated Neutral Density filters are darker on one edge and lighter on the other. They are great for keeping a bright sky toned down a bit so it doesn't get over exposed when the darker land area under it is exposed properly.
