HDR - High Dynamic Range / Re: Singel Image HDR
« on: October 05, 2014, 09:38:47 PM »
Hi,
   IMHO, may be something like this:
If meter show 1/100s, F4 @ ISO 200, mirror goes up once and sensor took 3 exposure of
1) 1/300s, F4, ISO 300,
2) 1/300s, F4, ISO 600, and
3) 1/300s, F4, ISO 1600.
   Combine all this 3 images to give a single shot HDR RAW. To the user, he took 1 shot, but actually the camera took 3 bracketed shots.

   Have a nice day.

Hi,
   Must be related to "Impossible", so
1) Canon take over of Nikon and Sony imaging divisions.
2) Canon new X-Ray DSLR (see through all your subject).
3) New sensor upgrade service for 7D2, 5D3, 6D and 1Dx.
4) New pixel-less FF DSLR with 8K Video (User selectable 12MP to 120MP).
5) New modular DSLR with entry, semi-pro and pro class body (user selectable AF module, sensor module, processing module, power module).
6) World first Nuclear powered grip... no more battery.
7) World first DSLR and lens with waterproof sensor and electronics (No more underwater case for your DSLR and you can change lens underwater).
8 ) A 36MP, 15fps, 65 all double cross point, eye control AF, 300-600mm F2.8-4L USM with selectable 1.4x and 2x TC built-in FF birder camera.

    Ha ha ha ha...  ;D ;D ;D

    Have a nice day.

Hi,
   +1 Yap... this is the most importance criteria of all.

    This is the reason why more people buy FF instead of medium format, this is the reason why more people buy 5D3 instead of 1Dx and this is the reason I want to buy the 7D2 instead of the 5D3.

   Have a nice day.

Hi,
   Animals behaviour shot... Look for the special moment the animal make or reaction to other animals or the environment... but this require great patient or good luck (at right place and at the right time).

   Have a nice day.

Canon General / Re: Financial Times - "Digital cameras: out of focus"
« on: October 02, 2014, 09:29:07 AM »
Hi,
   IMHO, yes, smartphone will kill the low end compact camera market, but also might increase high end compact and DSLR sales. Those user using smartphone camera most probably are not interested in photography in the first place, but once they shoot more with smartphone, they might be interested in photography and once they are interested in photography, they might buy a DSLR. Camera manufacturer should actually target those smartphone shooter by showing the different in quality and speed between a smartphone and a high end compact and DSLR.

   Have a nice day.

Third Party Manufacturers / Re: Nikon's 2.300$ D750 said to best 5DIII
« on: October 02, 2014, 08:44:42 AM »
I just have to laugh at most in this thread...

The premise at hand... Comparing a new camera to a camera going on 3 years-old and stating that the new one is improved.

Really.  Shocker?

The fact that it has taken x number of years is the real testament...

But what do we know? 

We do know the 7D MK II is shipping shortly and by all accounts appears again to be the king of the crops.  While some may say its low light or DR are not up to snuff it is much improved over the 7D and the AF system, FPS and general features are tops.

We know that the D800 was a POS and a disappointment... So much so that they released the 810 just about a year later.  I would be pretty pissed if I picked a camera up a few months after release and it was already outdated/replaced in a year.  Talk about taking a HIT on your investment. 

We know Canon looks to have plans for a High MP, 1Dx II and 5D MK IV in the pipeline in the next 3 - 12 months and likely the 1DX MK is announced before end of the year and 5D IV early next year.  Looking the the Digic 6 processors and the buffer capability of the 7D MK II both of these couple see marked improvements in FPS, AF and better sensors. 

Keep comparing to the past, all of these comparisons are moot and passing... Lets see how the 750 compared to the 5D MK IV
Hi,
   I think it might be D799 (Nikon running out of numbers) vs Canon 5D IV  :P

   By the way, I think sales of D750 will not be good... because every Nikon user thinking may be Nikon will be releasing a new model in the next few months...  :P

   Have a nice day.

EOS Bodies / Re: Next Rebel Going EVF? [CR1]
« on: October 02, 2014, 08:35:11 AM »
Hi,
    If going pure EVF mean it'll be mirrorless... 2 possibilities:
    1) Replace by EOS M or design a slim rebel and use EF-M mount.
    2) Remain the similar size as current rebel, so can still use EF mount and also a larger capacity battery.

    I hope at least is 2 as EVF need a lot of power...

    Have a nice day.

Hi,
   By the way, I just wonder is using carbon fibre for the front a good idea?? Carbon fibre is strong, but also will shatter under impact... I had seen quite a lot of drop camera and most of them the lens land first (especially with heavier lens) which mean the mount area of the camera will take quite a lot of impact... just wonder is the D750 front strong enough to withstand the force?? Will the carbon fibre front shatter?? I never see the front of any DSLR crack after a camera drop, so just wonder??  ::)

  Have a nice day.

Technical Support / Re: Downside Up?
« on: September 27, 2014, 11:18:01 PM »
Hi Folks.
I was out today doing some landscape shots with the camera upside down, came home and put them on the computer, clunky old laptop, where they were displayed inverted.
My question is why were they not displayed up the right way, I have rotation set to computer only on my 7D, shot raw only. Does this setting only affect JPEGs, does it only work for 90 degree rotation, i.e. portrait and cannot recognise an inverted camera?
I checked the software, Fast Stone Image Viewer, which was set to rotate according to exif data.
Is there a way to rotate the raw file, or is this not a good idea due to having to overwrite the original? Is there a way to get it to display upside up!

Thanks for your help.

Cheers, Graham.
Hi,
   Hmm... The question is why do you want to shoot with your camera upside down?? Both are in landscape orientation, so I wonder why you want to do that??

   Anyway, just rotate your image during post processing... you do post process your RAW file, right??

   Have a nice day.

Use the tripod center column reversed to get close to the ground.
Hi,
   Oh... didn't thought of that... :-[

   I don't think any software can rotate a Canon RAW file directly... you had just to rotate in the post...

   Have a nice day.

Photography Technique / Re: Noise in 5D III - Concern or my fault?
« on: September 27, 2014, 10:07:38 PM »
Hi,
   I suspect it's might be the "highlight tone priority" as this feature actually shoot in lower ISO and apply a tone curve which will preserves more highlight, but at the expense of increasing shadow noise.

  Have a nice day.

The image still shows the mirror.  We'll know when their seriously considering mirrorless when it goes away.
I'm in the late 30. I have high hope in canon ff mirrorless will be ready on my retirement  ;D
Hi,
   Just shoot with live view and you got your "mirrorless" camera.  :P

   Have a nice day.

Hi,
   Most lens are not design for pin-point light source especially those wide angle lens, so if shoot at wide open and view at 100%, most likely you'll be disappointed... stopping down one or two stops might help.

   Below is a website that might help you:
