Congrats on the lens ... the Tammy 17-50/2.8 is a fine lens on crop bodies. Had one when I was shooting Nikon crop. Sold after switching to Canon and going up to FF.
+1 @ much of the others. I'll add that you scene is inherently being shot with portions in two very different lighting conditions. Part shade, part full sunlight (the sky is also "full sunlight" if you will). Getting a correct exposure for two dynamically different light levels is essentially not possible with one exposure.
Think of it this way ... you're at the carnival and trying to knock over two milk bottles with the throw of one ball. The rules are you need to knock them down, but if one (or both) of them falls off the table, then you lose. You have to keep them both on the table, but you still have to knock them both over.
So, while you might be focused on where to throw the ball to get them both to fall, you also have to consider how hard to throw the ball so it is the "correct" force to knock them both over without them falling off the table.
Okay, so here's the twist:
While to you, they LOOK the same as you are standing there ... the reality is that one bottle is really heavy, the other is really light. The "correct" amount of force you need for one bottle is the "wrong" amount of force you need for the other bottle. Well, if you knew that you'd think ... I'd need to throw two different balls at two different speeds. With only one ball, I'll either throw too hard and the lighter one will fall off the table ... or, I'll throw too soft and the heavy one won't budge. You can try to "split the difference" and thrown just the right amount, but there really is no "split the diff" amount that will get them both if you hit them both at the same time (exact vector force application notwithstanding @ disclaimer for any theoretical physicists that might be lurking).
BTW, notice how when the operator knocks the bottles over ... he does so with his hand HOLDING the ball, one bottle at a time, where he can apply a DIFFERENT force to each bottle so it knocks down, but still doesn't fall off the table. You aren't able to perceive that he is applying two different amounts of force, so you ASSUME that it is possible if you do it "just right". The reality is that it is an impossible task if the weights are too far apart. Yet, you are deceived into believing that there is a "correct" amount that will be just right to do both, when the reality is that with only one ball to throw, it will be an exercise in concession of one for the other ... which ever what you try for.
So when we are shooting in mixed lighting exposure value situations, we have some decisions to make @ which lighting we are aiming for. Do we go for the heavy or light portion of the scene? Do we try to take one exposure that is "down the middle" or do we decide to take two throws at it, one for the heavy, one for the light (not allowed at the carnival, but we can do it) and then put the results of the two together.
Because when we are standing there looking at it ... it is more challenging to realize just how much difference there is (without proper objective metering info). The diff's can easily be 2 - 3 stops in normal shade/sky situations and even more in different conditions. The polarizer can help reduce this diff a bit in some scenarios due to the logarithmic values of exposure dynamic range, but it isn't a cure.
Camera's just don't see things quite the same way that we do when it comes to dynamic, mixed lighting, so we have to adjust our thinking a bit. People wouldn't normally think that the same looking milk bottles would weigh significantly different. Same goes for when we see portions of the scene that "look fine" to us, but they can have significantly different amounts of light in them ... i.e. more than can be properly handled with only one shot tossed at it. Such is the bane of many a landscape photo, that we either shoot diff lighting @ reduced dynamic range, apply ND filters (PL pseudo ND), apply multi-value expsoures, split the diff and PP or accept the sacrifices on one in favor of the other.
More than one way to skin the cat, but one shot can be a tough gig when two cats are standing very far apart.
Anyway, HTH and welcome to the PC Forum.
Bring on the pics.
