turvyT: I bet it still works faster than Canon bodies with Sony glass.

I don't think any pro photographer ever thought "I'd wish I could put Sony glass on my Canon bodies", they have more than enough choice as is.

dcolak: Check out the banding:

Surely it merits further investigation by DP

Interesting... Nice bit of detective work by bclaff and the others!

On article Throwback Thursday: The Canon PowerShot G3 (94 comments in total)
In reply to:

Imagemaven: I am a photographer for 45 years and after 25 years doing commercial work I began teaching. My first year our school bought 25 of these for students and they didn't last a semester and Canon would not fix them saying "undue wear and tear." We then bought 25 Nikon P and S's and 2 Nikon D100's. The small Nikon's lasted 6 years and the D100's are still going. Since we have enlarged our cage of equipment with many Nikon DSLR's and they all have performed flawlessly and never having to go out for repair.
Testimony to Nikon!

Maybe, out of habit, your first batch of students were constantly trying to change film with those G3's? ;-) I'm sure that if there truly was a problem with the G3's, we'll see several people replying this to your post...

My experience with one Casio (QV4000), four Canons (D60, 300D, 40D, 70D) and two Panasonic TZ's is that all of them can take a fair amount of abuse. I only had one of the Panasonics die on me once for no obvious reason, but I ascribe that to unfortunate coincidence.

When in doubt, ask Sansa for the meaning of the word "shift"...

The pictures give a fairly good impression of the feat he delivered. However, to better understand the "why" of this at first glance insane attempt, I suggest you read this article by one of his close friends: https://www.outsideonline.com/2190306/why-alex-honnolds-free-solo-scared-me

DPhotoWriter: I wonder how much a piece of land costs there?

One of the things we don't even know yet is whether Jupiter even HAS a solid core or weather it's all gas and liquids ;-)

Maybe DPR isn't the most obvious place to talk politics, but considering the topic of this article I reckon there should be room for just that. Either way, you should be able to distinguish a sound, respectful discussion from "flamewars"...

In some democracies, a change in their fundamental workings requires a 2/3rd majority instead of a simple majority. This makes it harder for a majority to oppress minority rights, so in my book that's a good thing. After all, isn't the core value of a democracy that it protects the fundamental rights of all of its citizens? To hear politicians claim "a clear victory", when in fact the population is as divided as it was on the Brexit vote, always reeks of political opportunism to me.

AstroStan: To the "experts" who ridicule people who ask "is this really what it looks like" (e.g. there are many wavelengths, goosed colors are "science", etc.): when you take a portrait of someone do you use x-rays? UV? IR? micro wave? Or do you goose the colors to make the subject vivid red? Being a troll seems to require not only abandoning politeness but also common sense.

Since you talk about "experts" - in plural - it must be that you perceived my replies to BBQue's post as trolling. I invite others to read trough that thread and judge for themselves...

Even more striking: 27.8 % of the people didn't vote, so with just 37.8 % voting "leave" and 34.7% voting "stay", the absolute difference between both camps was a mere 3 % of the British population...

bobbarber: Very cool.

One thing I don't understand. I've read the swirls on the surface are storms, with winds that rage at incredible velocities. Yet nothing seems to change in this flyby. Is the scale such that we can't see any change in the storms in this kind of time frame? Was I not looking closely enough?

Fantastic video!

The entire flyby sequence took only two hours, so even though the winds on the surface are ferocious, the image scale is so vast that there is little change from frame to frame. Think of hurricanes on Earth - seen from space and over a 2-hour timeframe, they appear as fairly static objects...

BBQue: Sehr gut! Are the colors real? With NASA one never knows if they publish real colors or if some graphics artist "filled it in" according to fantasy.

Who knows?

Look at this page, read NASA's intentions releasing the images to the public, and then hopefully you'll have changed your mind about NASA fooling people:

"So NASA once again deceived us with false, or as they prefer to say "enhanced" colors"

No they didn't! The colours were all there in the RAW images released to the public domain, and "processed to taste" by the people making the video. Go find the raws and try it yourself! Btw, do you use a polarizer for your earthen landscapes? Fake colours!

Here's a snippet from the news release about the first polar Juno flyby:
""First glimpse of Jupiter's north pole, and it looks like nothing we have seen or imagined before," said Scott Bolton, principal investigator of Juno from the Southwest Research Institute in San Antonio. "It's bluer in color up there than other parts of the planet, and there are a lot of storms. There is no sign of the latitudinal bands or zone and belts that we are used to -- this image is hardly recognizable as Jupiter."
The reason why this was all new is that, from our vantage point called Earth, we can hardly see this polar area since we see it side-on.

JunoCam uses normal RGB, plus a waveband "beyond" visible red to enhance contrast of the upper clouds. The images are often described as "enhanced-color", though, which I assume means they cranked saturation up to eleven to best see compositional differences. In short: the colors in the video are as someone "in love" might perceive them ;-)

And no, NASA usually doesn't have artists fill in colors according to fantasy. You should read and reflect on this: http://www.space.com/34146-fake-colors-nasa-photos-stop-complaining.html

On article First shots from new Nikon 28mm F1.4E ED (223 comments in total)

It truly is a great set of images, but it should not be compared directly with the results from regular lens tests. As others pointed out, a lot of the *wow* factor comes from the postprocessing. For instance:

You can often judge the quality of an article by the comments it garners, and there's quite a few interesting comments to be found here. Kudos Richard, both for the article and for highlighting more than a few "Editor's picks".

On photo Thunderheads With Egret in the Wings challenge (33 comments in total)

A composite indeed (both the clouds and the bird are in focus - that would be some amazing dof!) but as collages go it's pretty nice, like a painting.

On article Sony a9: Why being better might not be enough (766 comments in total)

Very interesting article, Richard, thanks. With the inertia of the big photography agencies in mind, it makes sense that Sony's first FF mirrorless offerings were aimed at tech-savvy enthusiasts, before expanding from there. At the same time, it means Canon and Nikon didn't need to panic straight away - they have the luxury of sticking to their tried-and-tested flagship dslr ranges, while observing what Sony does and deciding if/when/how to implement the new tech a few years down the line.

NCB: Is it just me, or are these pics not very good?

Tastes differ, nothing wrong with that. Personally I liked them, and I'm happy I found the gallery these shots were selected from:
https://www.frederikbuyckx.com/personal-work/wolf
You surely need to be a fan of dark, gloomy atmospheres to enjoy these... (and in fact I think it's quite a feat to make almost purely white images look gloomy)

Another of his galleries I enjoyed was the one on life in Albania:
https://www.frederikbuyckx.com/personal-work/moving-albania
I like this type of documentary-style photography, especially when the images show excellently balanced compositional elements.
