Gallery www.eorlova.com in preview

Ongoing project is going to end, sorry for pun :)

I am finishing coding of major part of website www.eorlova.com.

It is in preview mode now, and not all of content loaded, but if you are interesting about, just go and look at it.

Any comments and critics are welcome.

Some outstanding project

That was bit hard... It is always a trick how to understand what arts person wants. I have on-running project now to complete web-site for Eleonora Orlova. Goal is to make it as simple as possible, and purge a front not web site features, but arts of Eleonora. Project is going to end, and we have few results. Web page will be look like this:


This is a second stage of introducing to art world of Eleonora, after trials on few social web sites. Now, we know what, why and how to show.

So, we are in stage of technical clean up of web site functionality. Keep tuned, we will announce soon about official launch of this web resource.

Haiti in Daylight: "People suppose not to leave like in this house"

Haiti. Echo of Earthquake 2009 and always complicated economical and political situation are keeping people in hard life condition. Not always, not everybody, but most of them are leaving like this.

SLT-A77 Q&A: FPS vs Buffer?


Question:

Hi ,

I'm considering buying a slt-A77... What is the most important thing for me is the frame per second.
What I read is that the buffer is good only for 13 frames... Is that truth?
How many pictures can in one shoot? How long can we take pictures?

Thank you
Sebastien Ferron

Answer:

Simplifying and rephrasing a question of Sebastien a bit: will be 13 FPS working with no problem on SLT-A77? Here is not only buffering should be counted but also another factors of camera architecture, logic of in-body pre- and post-processing, type of memory cards used, and firmware loaded in body.

A bit of history...

First translucent camera I used was SLT-A55, and I've been a bit disappointed of real bug – 7 maximum shoots in raw I could do with this camera but only, after that camera became “frozen”. Same bug I was interested in SLT-A77, but...

We have a deal with software and hardware

SLT series are really fast processing bodies including build-in image post-processing. This is mostly in reason of “simplified” post-processing flow Sony uses in α cameras in respect of “EXMOR R” “BIZONE” chips they are using. So, 24.7 MP image can be “assembled” easy and this is not a problem in “in-body post-processing”. This part together with translucent technologies of SLT bodies making it really fast cam. Even more: all of pre-processing additional things like measurement, auto-focus, face-recognition, in-focus-object-tracking, etc. are not delaying at all during operations – they are just working and not slowing camera down. All of software features are very optimized with hardware.

Memory, memory, mem...

Another question is where this cam is writing to content (images and movies). SLT-A77 supports Memory Stick Pro Duo (any for pictures and Mark2 for video), Memory Stick Pro-HG Duo, and Class 4 (and higher) SD, SDHC and SDXC memory cards. If Memory Stick Pro just working, SD, SDHC, SDXC cards are stacked on class rating, what falls below a particular speed. Class 4 has 26x rating and 4.0 Mbps read/write spead, what is quite enough as minimal requirements for this camera. In practice, I am using Class 6 SDHC cards, what works just fine with SLT-A77. And do not ask me about read/write buffers in Sony made SD and Memory Stick readers - they are just working fine.

Always conditions

Vary valuable factor is existing what affects continuous shooting drive mode, bulb shutter speed usage and movie filming. It requires a lot of power to perform high quality movie recording or continuous shooting using the APS-C size image sensor. Therefore, if you continue to shoot, the temperature inside the camera will rise, especially that of the image sensor. In such cases, the camera is turned off automatically since higher temperatures affect the quality of the images or burden the internal mechanism of the camera. If you frequently recompose or shoot images after the power is turned on, the temperature inside the camera rises and the recording time available is shorter.

As cure of it (helping to me sometimes):

– Keep the camera out of direct sunlight.
– Turn the camera off when it is not being used.
– If possible, use a tripod and disable the SteadyShot function.

What is Sony saying?

Now we know where problems can be: speed of memory card, conditions of shooting, and environmental conditions as affecting “shooting continuation” factor. But what Sony is declaring?

May I correct a bit “input information”. Sony α SLT-A77V supports following Continuous Shooting speed (according to official source):

Continuous Advance Priority AE: Maximum 12 images/second
Continuous Shoot “Hi” (image recorded between the frames is displayed): Maximum 8 images/second
Continuous Shoot “Lo”: Maximum 3 images/second

Note: The speed of continuous shooting is slower, depending on shooting conditions (see above).

with maximum number of continuous shots:

in Continuous Advance Priority AE mode
Extra fine: 13 images
Fine: 17 images
Standard: 17 images
RAW & JPEG: 11 images
RAW: 13 images

in Continuous shooting
Extra fine: 13 images
Fine: 18 images
Standard: 18 images
RAW & JPEG: 11 images
RAW: 13 images

I have practiced with my SLT-A77V and all of above are near to same - “depending on shooting conditions”.

Summary
  1. Here is no 13FPS supported by SLT-A77
  2. SLT-A77 can perform 12FPS with exposure set in Continuous Advance Priority AE mode
  3. Bufferisation is not a problem here and not related in general
  4. pay attention to memory cards you will use with
  5. pay attention to environmental factors
PS: Why I mentioned SLT-A55 above? Just because my problem was in incorrect settings and very hot temperature of air around. SLT-A55 is working fine in Cont.Shoot Drive Mode if follow by rules described in this cam Manual.

Bit more than just 12FPS vs Buffer... hah!
