Sony A7rII: Shooting very high ISO and get clean images with (almost) no noise (by Dierk Topp)
This is a guest posy from Dierk Topp:
Shooting very high ISO and get clean images with (almost) no noise
A few days ago I saw a great tutorial about achieving high ISO images with low or almost no noise. I found it at lenswork.com, my favorite photo site with incredible picture series. The link to the tutorial follows at the end.
In astro photography this method seems to be very common, but using it for any hand held shooting is something different.
The main idea is, that by stacking multiple shots of exactly the same scene or object the different noise patterns of the images get combined and disappear. This can be very effective with high ISO and especially with small sensors. You set the camera on Hi continuous shooting and shoot a series of pictures. You will get a feeling for the amount of pictures depending of the exposure time it may take a while.
I got so exited, that I went out and started shooting the Christmas tree in front of our beautiful townhall with up to ISO 6.400. After learning the processing in PS I found, that I should try even higher ISO the next day. The problem that day was, that it was very windy and the tree and the flags where moving a lot.
Here is my first test shot
made with the Sony A7RII and the Sony 16-35mm Vario-Tessar T FE F4 ZA OSS hand held 1/20 sec. at ISO 6.400, stacked from 12 images
if you don’t have or can use a tripod shoot some images (better more than 4) with high ISO hand held
load them into CS as layers
edit: Auto-Allign Layers
layers: convert to smart objects
layers: Smart Objects – Stack mode – Mean
and try to find the noise :-)

Kai: “Sony RX0 vs GoPro Hero 6 – The GoPro Killer?”
Kai: “Sony’s latest water-resistant, shock-resistant camera looks set to be tough competition for the GoPro Hero 6 with its bigger 1″ sensor and S-Log2 but can it outdo the most popular action camera around?”
And here is the RX0 presentation video from Sony Europe:

First video showing INCREDIBLE tethering speeds of the a7RIII
Evan sent me his latest video showing INCREDIBLE tethering speeds of the a7RIII:
Shooting tethered with the Sony a7RIII over USB-C to a Microsoft Surface Book 2, using Profoto B1 lights, I test the tether speed of single shot for the first part of the shoot and then burst speed in the second part.

Imaging Resource claims the A7rIII is the “best overall professional camera on the market today”
Imaging Resource really likes the new Sony A7rIII:
Does the Sony A7R III deserve the hype and excitement it has been getting across the photo community? After several days shooting with it and numerous hours working with both photos and videos produced by it, I have to say yes, it absolutely does. The Sony A7R III does a fantastic job addressing the concerns fans of the A7R II had, while simultaneously introducing new features perhaps few asked for.
It’s pretty clear that Sony was actively listening and taking notes on what improvements they needed to make to their third-generation A7R camera. This is probably the first camera I’ve personally ever shot with that feels like a true advancement in areas in which its predecessor was decidedly weak.
Also Jim Kasson is happy with the camera:
The camera is faster and more responsive than the a7RII in almost every way, which translates to greater confidence and less tension when shooting an event. That seems to include the autofocusing, although I can’t be sure without a real test.
ThePhoBlographer posted their full review too:
I mean, what is there to not like. Anything that isn’t that great about the Sony a7r III can be overcome and in no way do I see it being a burden in the long run. The Sony a7r III is replacing my Sony a7 as my main camera, although I still still keep the original due to just how good it still is. I recommend the Sony a7r III for working professionals and semi-professionals. And if you get it, I strongly recommend using it with Capture One to make the most of it.
