If you record audio, a pop filter is going to be one of your most important secret weapons.

The little pressure waves that you emit when speaking words like party, pop, pepper or platypus hit the membrane of the microphone like little explosions. That's why they are called plosives and you really want to avoid them.

One way to keep them from hitting the membrane is to use a pop filter, which is a contraption covered in two layers of thin mesh that you can put between your mouth and your microphone. When I started out recording, I used a wire coat hanger and pantyhose

Twitter does have a sense of humor!

tl;dr: the LR3 to LR4 update ate my tone curve adjustments for breakfast.

Update 05/02/2012: It's been almost two months and Adobe still hasn't officially updated Lightroom 4.0. Here are some of my thoughts on it.

Update 03/06/2012: Here is the bug report that I filed with Adobe. Please consider to +1 it on their site to help raise awareness of the issue.

Update 03/07/2012: Tom Hogarty, Lightroom Product Manager has posted the following update as a response to the bug report: "Thanks Chris. We've been investigating this issue throughout the day and hope to have an update soon. Thanks for your patience and all of the detail you've provided."

Update 03/11/2012: It's 4 days later and the bug report now has 55 +1's. Some of the commenters are starting to get really impatient.

Update 03/12/2012: I received a mail with a script and test instructions from Tom Hogarty. The script recovers lost tone curves and it mostly worked. It's just an alpha test version, so it still has a few side effects though. Adobe is on the right track with this, but they're not there yet. This still has to be tested more and then needs to make it into an update. I posted my findings in the bug report. 62 +1s now by the way.

Update 03/14/2012: Since Adobe provided the test script to some of those who had the issue (this includes me), there have been mixed messages on the bug report thread. It works for some, some have found other issues. It generally worked for me, even though I ran into another potential problem during testing the fix. This bug is also on the top of the list of Adobe's Lightroom 4 Hot Issues, so even though it's been eight days, there's still hope they will eventually fix it. Until then I'm staying on LR3 and I'm just a little annoyed that I paid for an update that so far is unusable to me.

I just updated from Lightroom 3.6 to Lightroom 4. The new features and the 50% price drop made it look like a no-brainer. I loved the product from the first beta of version 1. I even recorded two video workshops for Lightroom (in German).

If you've listened to Tips from the Top Floor or Happy Shooting, you know that Lightroom is the hub for my photography and you'd have to dangle quite a juicy carrot in front of me to make me give it up. Very juicy.

Unfortunately I have to report that after the update, Lightroom 4 seems to have eaten up all my tone curve adjustments and replaced them with some defaults.

Here's a picture in Lightroom 3, note its histogram:
