Lunchtime Photo

A few weeks ago I put up a picture of the Sacramento delta taken from an airplane window. As usual, I got queries from a couple of people asking how I get such good pictures when all they get is smudgy crap when they try taking photos from an airplane. Part of the answer is luck: a seat up front ahead of the wing; a window that’s not too scratched up; the sun in the right place; etc. But the bulk of the answer is Photoshop. Here’s a demonstration using a picture I took shortly after takeoff from John Wayne airport in Orange County. This is the original:

Not so good! First, let’s straighten the horizon line:

Then crop:

Now let’s fill in the blank spot on the left. Luckily, there’s nothing there but plain sky, so this is easy:

The next step is to dehaze the picture. This is one of the most frequently misused Photoshop filters, but that’s mainly because people—quite understandably—try to use it to reduce the haze in pictures. I find dehaze useful in modest amounts for many things, but not for removing real-life haze. In this case, however, the dirty airplane window basically acts like a uniform haze over the entire picture, and the dehaze filter does a pretty good job of removing it:

Thanks to the airplane window, the white balance of the picture is off, so let’s correct that:

Finally, we need to clean up the sky. There’s a window smudge on the right we need to get rid of, and some artifacts that are best dealt with by simply blurring the entire area. I’m also going to modify the color a bit to get rid of the yellowish haze on the horizon:

That was a little sloppy. Sorry. But it gives you a sense of what you can do with the sky if it’s not to your liking. The last step is to reduce the picture to fit on the blog and then sharpen it since the reduction process introduces some blur. Some pictures take sharpening well and some don’t, so this is a matter of taste. I’m showing it here so you can see the difference. And here it is:

THE TRUTH IS...

what drives Mother Jones' team of 50-plus journalists. The truth is powerful, as evidenced by how hard those with something to hide, or profit to gain, seek to discredit it. The truth, stated boldly and reported meticulously, is what draws so many readers to Mother Jones.

And the truth is, going into the final 4 days of the year we still needed to raise $TK to hit our $350,000 goal and start 2021 on track. It's nerve-wracking, wondering if the big spike we normally see at the end of December is going to be another thing that doesn't go as planned in 2020, or worse, if, now that Donald Trump is set to leave the White House (for longer than a taxpayer-funded golf trip to a property he owns), folks might be pulling back from fighting for the truth and a democracy and think the hard work is done.

It's not, and if you can right now, please consider a year-end donation to support our team's fearless nonprofit journalism so we can close that big fundraising gap and finish the year strong, ready for all that's ahead in 2021. Whether you can give $5 or $500, it all matters in keeping us charging hard, and we'd be grateful.
