How can I avoid camera shake when taking auto-bracketed images for HDR?

[stephen88]

Hello,

 

I have recently purchased an a7R and a 24-70mm FE Lens, and have been wanting to take some photos using the auto-bracketing feature to make HDR images. 

 

My issue is that holding down the shutter while all the images are taken is known to cause camera shake. I have been looking around various websites but there's nothing too clear about it. 

 

I have seen there is a Sony RMTDSLR2 Wireless Remote available, but I am uncertain of whether this will do what I am looking for, and if it does, I have seen elsewhere that you have to point it right in front of the camera (not from behind it) to take photos. 

 

There is also an iOS app with added hardware called Triggertrap but that looks quite complicated and again I don't know if that will do what I'm looking for.

 

Just looking for a simple way to take HDR photos on the a7R without the camera shaking while I hold down the shutter button. 

 

Thank you

Set the shutter to release on a 2 second timer. Otherwise use the WIFI connection.

Thanks for the reply! Ah I'll need to give the 2 second timer a try on the a7R. I was under the impression that it wouldn't work for taking multiple auto-bracketed images. What is meant by use the WiFi connection? Sorry I'm such a newbie!

WiFi connection refers to the fact that Sony's ILCE cameras can be connected to, and controlled by smartphones via wifi. Read the manual or search on Youtube.

Brilliant, thanks very much guys.

This seems backwards to me ... this phrase especially:

 

"holding down the shutter while all the images are taken is known to cause camera shake."

 

Cuz hi speed continuous shooting is a good way to assure sharp images, but only

the frames after the 1st frame cuz it can suffer from pushing the button down.

The problem of camera shake with SONY A mount becomes more serious,  when using the long telephoto lenses. This issue gets further amplified when doing continuous shooting of moving subjects like in wildlife (esp. Birds in flight) and sports. I realized this when I tested the Sony A mount in  continuous shooting of birds in flight.

 

I  found that in most occasions,  from 3rd image onwards, the series of images coming out of the camera is not sharp.  This point was highlighted in one of the internet articles by a pro photographer, who said that his/her rate of "in focus shots" to "total shots taken" of a sport event was 50% with a  Sony, whilst Nikon and Canon gave around 90%. 

 

Sony and Nikon uses the same processor but Nikon's keep on producing series of sharp images from much worse AF systems than what we get from Sony. When you get a sharp image with a Sony-believe me it is sharper than any other, but, generally on a percentage, Nikon and Canon, wins the race.

 

I believe the problem lies when the camera sensor has to do too many things with Sony and it fails. I believe that this is the reason why even SONY's "LOCK ON AF CONTINUOUS" fails when it comes to tracking animals  who are (Like a Bird) moving unpredictably. 

 

My belief is that to start off, the camera sensor need a steady image to do a sharp focus on it by use of its processor. SONY needs a system of "in body stabilization" which has to work first and stabilize the image and then use its superior AF system for focus on the subject. I believe that if Sony engineers can figure a method to do this, then world of Photography will say bye to Canon and Nikon, at least when it comes to photography of Sports and Wild life.

Lower hit ratio, but still successful, at 50%. And you say

that Sony's 50% is sharper than Nikon's 90%, and you

suspect the processor of being overworked. Processor

issue or not, sounds like quality instead of quantity, the

deal I prefer and perhaps Sony also prefers, or caters to

those users with that preference. IOW, maybe it's not an

overworked processor, just a different algoriddm. There's

no competition, no winners/losers, in that scenario, just

a difference, a matter of choice. With no competition it

follows that the issue will not be pursued in the manner

you suggest, but will simply gradually yield to the usual

inexorable pursuit of improvements of the "because we

can - and we can convince users they need it"[u/] variety.

 

Proof ? or at least a supporting argument ? Well, nobody

really needed stabilization or tracking before it became

available, and the earliest versions were sold as state

of the art to users who'd become convinced of a need for

these technologies which were far more crudely primitive

than the technology about which you are currently griping.

 

Tracking will NEVER track anything truly unpredictable, as

tracking IS predicting. The success of AF tracking depends

on the robofocus noticing and analyzing predictable small

patterns of behavior. It used to be the user's job to do that,

but users depended upon more information, and "larger"

information, than the AF tracking can access. The camera

brain only knows what it sees, and deals with information

of a "smaller" more detailed type. It knows nothing of the

rules and strategies of sports, or the behavior of wildlife,

which is the "larger" information that the user is expected

to provide.

 

Acoarst none of the above addresses the HDR situation. For

reducing shake while bracketing for HDR raise the ISO. The

HDR process greatly reduces noise, similar to the multiframe

noise reduction feature built into some Sony cameras. If the

working contexts allows, use ISO bracketing so that not all

your collected exposures are subject to a noise increase.
