Using the EV Compensation

So I was messing around lastnight with setting that off 0 (both + and - amounts), and it seemed to me that when I loaded up the raw image in LR, that it would load the original (saying Loading) then once it was done, this pale overlay was added to the image (I think I really only got this on + values of EV). The loading image was much richer and then once it was done it was pale and kind of gross...

My biggest question is this normal, is this what EV compensation will do to the image when PP? If that's the case it seems like something I don't want to use. The loading image was much better looking and I really have to work at getting it back - even reducing the exposure didn't help, I think there's some contrast and clarity that have to tweaked...

When you shoot in RAW, the camera doesn't apply any image processing. You have to make the photo pop on your own, which can actually be challenging at times (which is why I recommend RAW+, as the JPEGs give you a good starting point). What you probably saw is the processed JPEG preview thumbnail which was shown prior to the actual RAW data.

Interesting, but I've never noticed this before - I don't remember off the top of my head which raw i'm using...but I'm pretty sure it's never done this pale overlay before until I messed with EV. I'll play around tonight and see what happens setting EV to 0 and maybe switching lenses around. There's a couple of variables I need to verify, I just wanted to get some ideas of what it is...

If you could post a screenshot, that would be great!

When you set the EV to overexpose, the extra contrast the jpeg engine puts in gets more obvious. In RAW non of that processing matters though as soon as the program is done making it's own preview instead of the bundled one. RAW is a raw file and it looks pale because it's neutral and ready to get optimally post-processed by you.

This has nothing to do with EV, but with the preview jpeg that is embedded in the raw container. If you use the Pentax raw processing software and select the same processing as the one you have in camera - the photo will look the same.
If you want to see a thumbnail more similar to the raw file, choose "Natural" as the jpeg mode in the Info menu.
EV+/- will simply choose settings (shutter, aperture, ISO) that makes the exposure darker or brighter. The best way to test this feature is to use M mode, choose settings, press Green button to meter, and then choose bracketing. Then the camera will quickly take three photos of different EV

I had a hard time understanding what the problem was. But I have one thing to say, if you want your final results to look better you have to shoot RAW. You'll have less pictures, because you'll spend more time with PP, but they will look better in the end.

That "pale" look is the raw data from the sensor, plus some "default interpretation" by Lightroom, if any.
That's your starting point.
You can choose how much contrast you want, how much saturation, tinker with the exposure etc...

Think of it as playing with a negative in a darkroom...
In this article there is a facsimile of the first contact print of the famous "Moonlight" photo by Ansel Adams (second picture, scroll down a bit)

Your RAW are a bit like it, dull and lifeless.
Then there's the darkroom/Lightroom and you can get your final print just as you like it.

It's not the pale overlay which is added but the JPEG preview that is removed.

Welp, now I feel ridiculous, I got home all ready to take some screen shots of what I was describing...but low and behold it didn't do it. The loading and loaded images looked the same - but I SWEAR it was doing something last night...ahh well, there's still some good nuggets of info in here.

Thanks for all the responses! I really appreciate all your help!

Well, there's loads of way it could have happened... maybe you changed some settings in the develop module, maybe you're already seeing the "pale" look because it rendered the previews based on it, but can't recognize it because you weren't shown the embedded jpeg before, or maybe it's the work of the Lightroom fairies, that change things at night.
I'm serious, they do exist, it happens to me as well!

Any chance you unknowingly had the "Muted" JPEG setting on?

I loaded the same sets I had the night before, and none of them changed as they had...I changed no settings and didn't even load new images - so I guess I'll chalk it up to LR Fairies...lol

Try re-shooting and starting over with an "untouched" preview image. Depending on the program you may now be seeing the viewable thumbnail/image after the initial application of the JPG settings.

Also note that EV correction is available to either preemptively compensate for a "mistake" in the "normal" metering evaluation or to produce HDR source files so if normal is "good" the + and - shots will be . . . well, less good? for want of a better description.
