Oh silly me - I didn't check Flikr but just downloaded the shot *rolls eyes*

I think I can see the problem - you have used Matrix (multi-segment) metering which tries to evaluate the whole scene. Someone please correct me if they think this is the wrong conclusion !

If you switched to Spot then you can do one of two things - the cows are in the centre of the shot so the Spot metering will be directly on them (assuming your focus point is the centre point) and should expose correctly for the cows (but not the snow) or you could try to get the best of both worlds by using the Exposure Lock button (AE-L) and firstly spot metering on a neutral area of the scene and then depressing the AE-L before recomposing and taking your shot.

Good luck trying this !

Tried to find the Exif but it seems it's been stripped off the last shot.

These are very nice subject shots but the snow has been blown out (no surprise - massive contrast) and the last shot especially is very puzzling as no matter spot or centre metering it should have correctly exposed for the cows and blown out the snow (was it set to matrix ?). Strange, like to see the Exif for that one if you have it.

With such high contrast in the scene maybe the only way around it would be to combine shots, one exposed correctly for the cows and one for the snow !

What a lovely looking bird ! First shot is excellent, eye is sharp and DoF perfect - second I'm afraid is under-exposed, or maybe some added fill light in LR or A3 could cure it.

Absolutely and, as JR said above, they make great portrait / street lenses too (N.B. Not the MPE 65 if you ever use Canon - it is strictly a macro only lense).

Here are a couple of samples of street shots with the Tamron SP 90 Di Macro :

Excellent frescos - do you know when they were painted ?

Interesting story ... would love to see the shot to go with it !

It's missing Jeff

Oops ... there it is (must be very slow to load) ! What a pity that it's no longer in frequent use.

Que ? Now that is something worth seeing !

It's a female you wally - no it's not poo !

I have been trying to capture a shot like #2 of my pet GSD for a year now ! It is really tough to do and that is really a superb shot - I don't think other people appreciate just how difficult it is when it's your own pet and they jump all over you when you're trying to get them to jump !

Lovely series.
