On article Behind the scenes: Shooting Lamborghinis in the snow (84 comments in total)
In reply to:

fireplace33: Sometime last month DPR showed us a video of a photographer being hit by rally car. Most here agreed that it is a particularly stupid thing to do to stand on the outside curve of such a race track. Well this guy seems to have documented his "stupidity" too, by doing just that, starting in the video at 7:22

well good luck with that!

On photo Blue and yellow in water in the Ink and water challenge (12 comments in total)

Thanks for all the nice comments :-)
I printed 6 images in this style 75×50 cm and displayed them in nice, well lit, frames in an exhibition. Afterwards we auctioned them and donated all the proceeds to a charity for the homeless.

So that was a good use for an atomic bomb, as some descibed it below :-)

André BARELIER: Amazing. I've read your post with the explanations.
This kind of picture needs some work, but the result is magic.
Congratulations!
André

Thanks!

On photo The Plug Has Been Pulled in the Liquids - Macro Only challenge (3 comments in total)

Great shot !!!! and looks like the F number was just right to me.
So close to the subject and with 60mm FL on a FF camera, F16 gives you only about 2-4 cm DOF , Just right! ...as the first place confirms :-)

The Name is Bond: Sheesh, some people are easily pleased.

it delivered it's one trick on the first 10 seconds. And it was far too quick. There's no ability to take it in and savour which might have saved it for me.

Lack of artistry, IMO. Either the guy is very young or he's not got good counsel. And the music?!?!?! His girl friend giving him advice here? It's no good asking people who love you. They'll be bursting with pride for you over any old cr*p.

In any case, if it made it to the front of dpreview, then evidently I haven't got the popular touch that makes the mediocre so successful and money-making.

Well, I guess I'm one of the easily pleased :-)

Beautiful shot!
Love that low sun.
My humble attempt at something similar in Scotland is over on the landscape forum.

fireplace33: This monster looks good but is1.2kg.
Can anyone estimate what the, not yet released, 50-200 2.8-4 lens would/could weigh?

So I guess we just have to wait and see what they decide to do with the new 50-200
Seems like F2.8-4 is fixed already but they still have options to play with. I'm hoping for excellent IQ (on a par with the 35-100 which I already have) and small size and weight. Not so bothered, in this case, about close focussing. We'll see, time will tell

The 35-100 is a constant 2.8 and weighs in at only 375g. Does the physics for change up to 50-200 2.
8-4 really need that much weight increase?
The 40-150 2.8 is 880g without the tc :-(

ACDSee ultimate !
Thank goodness I've been using ACDSee for years.
Very fast , good database features, excellent raw developer, multitude of easy to use editing tools including layers.
Fulfills all my needs. Results can be seen on my website.

The previous gen 7 is not completely compatible with windows 7 !
The IT department in the company whete I work forbids the gen 7chip until windows 10 can be used. But that is delayed because of security and spyware type issues with win 10 :-(
So is this new gen 8 chip completly compatible with win 7 ?

Thanks for the inspiration :-)
Nice article.
Had some fun after reading this when I tried this myself and posted the results here if anyone wants to see.

fireplace33: Thought provoking article.
One thing I think some commenters seem to overlook is that at higher light intensities the noise is actually larger!
There isn’t a constant size of noise at all intensity levels, as I think some commenters are assuming.
Now we all know, after Richard’s many articles, that shot noise is the dominant noise source in an image (Poisson distribution), and the Standard deviation of that Shot noise coming from a light source is like sqrt(average number of photons arriving)
So, at higher light intensity levels, although the Signal to noise RATIO is much better, the ABSOLUTE number of digitised levels of noise is also GREATER vs. lower light levels
So at higher levels, a finer resolution of levels (more bit depth) will record the shot noise better, as Richard stated

e.g.
10 photons (S/N ratio is bad), something like +/-3 photons shot noise
10000 photons (S/N ration is much better) but something like +/-100 photons are shot noise
True or false? :-)

@ Arun H
Agree about read noise becoming more important at low levels

> "bottom line"
yes, for those reasons, for some time now I've been shooting with the "ETTR at lowest possible ISO" method to get the biggest signal and largest DR with lowest noise onto the sensor.
In PP I'll adjust and reduce the levels as necessary.

Agree !
.. a better S/N RATIO is good. And at high light levels it doesn't help much to differerentiate between 2 output values that are very close to each other since the absolute value of the noise is much bigger than these 2 adjacent bit values (at high light levels)

At the lower light levels you'll want those values to be close together to differentiate between them and get more DR but as we all know the noise starts to show it's ugly head when the light goes down. (because the S/N ratio is smaller at lower light levels)

This is a link to a post on the landscape forum where I just posted some waterfall shots from this weekend with similar equipment.
Oly Omd em5ii + 12-40 f2.8.
A great lens. And a nice lightweight system compared to my heavier Nikon gear.
The stabiliser on the oly is truely amazing! Surprisingly it allows for better handheld shots whem the light levels go down, despite the smaller sensor !

On article Caltech research team develops lensless camera (61 comments in total)

Some time ago, I used to work as an ultrasound physicist developing machines for medical diagnostic imaging.
This idea reminds me of the phased arrays used in the ultrasound world to modify the focus of the ultrasound probe in both transmission and receive modes.
Very effective and superb ultrasound images produced, despite of course their own special set of limitations and artefacts.
Many here have probably even seen the very first photo of their children with this phased array technique!
… and I thought working at the speed of sound was difficult. Light is a whole new ball game 😉
