My initial impression was that the PNG looks ever-so-slightly sharper. But not enough to justify its much larger file size vs the JPG, if you're thinking in terms of websites/bandwidth.
PNG is a lossless format, so it's always going to be much larger in file size. But by its nature it will also be as close to the original as possible.
For this kind of image, though, with a lot of color gradation, the visible difference is minuscule, especially if the JPEG is saved at a high quality, and the JPEG file will be a lot smaller.
PNG images really work much better with line art, or images with lots of solid colors. And the real advantage of PNG files, for web design anyway, is that they have a true alpha channel for transparency.
For putting photos on the web, JPEG is almost always going to be the better choice in terms of the tradeoff between file size and image quality.
Thank you for that, as long as I'm tuning images up for various formats, I figured to set one up for LGF.
And to share a little news-I hired a lady to make a wordpress blog for me with a e commerce retail front end so people can buy prints or high res digital files. Hopefully a retina display friendly site.
I vote for the top image. Put aside questions of file size. Just which looks better.
Slightly off topic? I had the opportunity once to walk up to a controlled, rather large natural gas fire. At closest approach, it was maybe 10 yards away, and filled much of my view.
That lasted less than two seconds, of course. Those things are hot. But the sight was unforgettable. Flames such as the one in the photo, when live and moving, are hypnotic and fascinating. "Towering Inferno" did its best to convey that. But the real thing is more impressive.
My only input is the the second image looks over-exposed.
:)
Heh, I actually gravitated towards that one because it looked brighter.
I don't do as much web work as I should, but I have rarely encountered PNGs over the years. It's the default format for Apple's screenshots now, but that's about it. Any web wonks out there actually using it for real work?

IIRC, PNG is an open format as well, created in response to some licensing issues around the GIF format.
FYI-That flame is from a 100,000 BTU blast furnace, with the lid removed just before the air fan spins up and adds oxygen and make the fire hotter and stay down in the furnace. For perspective that flame was about eight feet tall. I shot it at 1/8000th of a second shutter speed.
the furnace with the air boost reaches 2000F.

I grew up about 30 miles North of Chris Herren. Being the same age, I followed his career from Highschool through College at Fresno State then to the hometown Boston Celtics via the Denver Nuggets. So his fall from grace (after what appeared to be a remarkable recovery) was disappointing. This article... Herren tells Bromfield teens and parents tough truths ...sums up what Herren ...
It must be a slow news day for the right wing media, especially after President Obama shut down a couple of conspiracy theories, or at least somewhat. So, Drudge Report, Twitchy and the Weekly Standard have stumbled on to Obama's next dastardly deed. President Obama (wait for it) uses an umbrella when it rains. That rat bastard! Obama acts like he's the President ...

It's all about the paper. For many years I have been among that class of citizens anxiously desiring health insurance coverage for all Americans. I'd thought my reasons were sound: the country is fabulously wealthy; if we can afford luxurious salaries for sports people, media personalities, Wall Street financiers, the least we can do is ensure a minimal standard of life for the least ...
Should you ever be accused of terrorism, here's what you should do: Snitch on your friends, demand to be placed under witness protection, then fly out of the country.

I saw the The “What to Do in New York City” Open Thread and decided to ask a similar question about San Francisco.

Please keep in mind these are older folks and on the ...

Chalk up another victory for the Great Climate Change Hoax, and all those greedy scientists who invented it so they can get rich on grant money while they force oil company executives to sell apples on the sidewalk and sleep on steam grates.

Rep. Trey Radel (R-FL) told NowThisNews on Wednesday that he loves “so-called gangsta rap,” and especially hip-hop group Public Enemy, because he feels the song “Fight the Power” somehow mirrors his own struggles in Washington, D.C. and the scandals of the Obama administration. “This is a song that came out really, if you really get down to it, in many reflects the conservative ...

We are in the midst of the worst Washington scandal since Watergate. The reputation of the Obama White House has, among conservatives, gone from sketchy to sinister, and, among liberals, from unsatisfying to dangerous. No one likes what they're seeing. The Justice Department assault on the Associated Press and the ugly politicization of the Internal Revenue Service have left the administration's credibility deeply, ...

Political discourse in America has reached levels of douchebaggery previously only theorized about but never observed, like conversational dark matter. We're in a whole new world of hating people based solely on their opinions on a few key issues, and since this is unexplored territory, our conversations about politics are usually only a couple notches beyond the "hold your breath until the other ...
Los Angeles leaders say the Los Angeles Police Department has undergone a dramatic transformation since federal oversight of the agency was ordered 12 years ago. The dismissal Wednesday of the so-called consent decree, which arose largely out of the Rampart corruption scandal and addressed basic problems of accountability that stretched back decades, delivered a largely symbolic, but nonetheless important milestone for the LAPD ...
Seems a good way to solicit ideas for touristing destinations and activities. Will have 4-5 days so some opportunity for visiting multiple sites. And since I do have an interest in history and military history items in that area will be welcome suggestions. (The USS Midway down in San Diego is already on the list.) If there is anything California-geology related that would be ...
