Here is my first shot at exposure blending. I'm sure if I gave the 2 files to someone else it would turn out better but some C&C are what I need!

good work. there are holos at coast line, not so serius as you can guasian blur the mask(usually heavily)
that you use for masking and fine tune the mask with soft brush (it is usually very quick easy does not need any skill).

It's a nice shot, but about one stop darker would work better for me.

"Halos" ; )
Those are always a problem with blended images, & one of the first things that I notice, so you ned to do a little more work on it.

One of the things that takes practice and observation is getting the blend correct - not in terms of masking, etc., that is a mechanical process. The fact that you are making a blend is because, typically, there are generally two different levels of scene illumination that challenge or exceed the camera'/raw converter when trying to capture and render that scene from a single shot. So, you take two exposures and blend them, getting the best pixels from each shot and making a composite image from the two. Or you process the same image twice, etc.

Great. So far, so good.

However, in doing so you are compressing the tonal range of the scene to get all of that dynamic range into a single image. Moreover, you are, more or less, compressing the tonal range arbitrarily. This leads to unnatural images. Think about the relative levels of scene luminance and how you can reestablish that once you blend the two sets of pixels into a single good working set. Make notes (mental or otherwise) when you shoot the scene, take meter readings, etc. to get a feel for how relatively bright one critical area is compared to others. This will help you achieve a more natural result when you reestablish contrast.

If the scene were uniformly bright, then exposure blending would not be necessary.

Have fun!

Still trying to make sense out of "However, in doing so you are compressing the tonal range of the scene to get all of that dynamic range into a single image. "... I'll try to figure it out on my own, but if I can't, I'll be back here asking for an explanation...

I should be more explicit - you are compressing the tonal range of the scene into the range that your device (display, printer, etc.) can render.

A better non-destructive way is to add a feather to the mask in the Properties section in Photoshop, this way it preserves the original mask but adjusts it anyway. I usually go between 50 and 100px. If you want to go further, click the Mask edge button to refine it more.

And to reduce the dynamic range a bit, you can adjust the 'Density' of the mask, so the image shows through the masked area a bit more - kinda like an opacity setting for the mask.
