Canon General / Re: Canon to Buy Video Surveillance Leader Axis for $2.8b

How much DR?

Use common sense people. Choose the lowest value.

The camera isn't even released and Canon marketing may be watching the poll to see what you are willing to pay.

I am going to be so upset with this camera.

It should have been able to do 12 fps and noise improvement so we can get great results at 12800.
It should have had GPS, WIFI and Pop Up Flash.
It should shoot 4K video (even though it would have 42 million wasted pixels since 4K is only 8 mp).

Any way I am so upset.

I wish they would announce this thing so I can get my pre-order in.

Oh, and that will upset me as well. I want this camera released now, not in a few months.

Oh no, not again. Why do some people keep complaining that a soon to be released camera is not made to satisfy their personal needs. To my mind, this camera is to a certain degree a 1ds iii successor aimed at studio photographers, portrait and landscape shooters and maybe for macro. Why would you expect it to have 12 fps? Why does it have to have GPS and WIFI, and 4k video? If that's the case, what would make other people to buy 5div with (I guess) all these features?

Dude smile. The guy is joking. OBVIOUSLY.

It seems to me that Canon has abandoned us EOS1D users...such a pitty.

The 1DX is targeted at those shooting for newspaper and magazines. And that is why the D4 doesn't have a large megapixel count either.

When the maximum print size is A4, you don't need 20+MP.

First point is an assumption. Second is false.

Magiclangern provides a button to "expose to the right". Adjust exposure in postprocessing to fit your needs. Problem solved, case closed.

And how, exactly, do you do that? Because if you are using the 'Blacks', 'Shadows', 'Exposure', 'Highlights', or 'Whites' sliders you are not getting the tonality of the scene.

If you use tone curves on each colour channel seperately, if you are using the camera calibration panel etc then yu might be getting close.

You seem to be missing the point that 'simple' adjustments to an overexposed file do not get you back to the same tonality as a 'correctly' exposed file.

The RAW data is linear. If you expose to the right, you just collect more photons. In software you have to reduce (or increase) the exposure by the same amount that you adjusted while taking the picture. Then you have the same raw data without blown highlights (when decreasing exposure taking the picture) or with less noise (when increasing exposure when taking the picture).

You do not need to change the channels separately. You do not need to change the tonality curve.

The required correction is only one single value. E. g. +2EV while taking the picture and then -2EV to reverse that effect in software.

That is the theory and software which does that is fine but there are many things that can go wrong. One big difference is the tonality curve of the camera (software) which is applied to convert linear RAW data to JPEG values. You cannot work with those JPEGs, you need linear RAW. But even then the RAW is preprocessed by software and that might do some things like change the color of dark/bright parts. E.g. reduce the color of dark parts to avoid color noise.

You can simply test your software. Switch to manual mode and take a photo of some dark objects before a dominant white wall and expose like the camera would do (make the white wall grey). Then expose to the right and remember how many EV you increased the exposure. E.g. 1/100s camera exposure vs 1/25s ETTR exposure = +2EV. Then use the RAW files and convert them with your software and apply -2EV exposure to the second picture. Now they should have EXACTLY the same color properties but the ETTR picture should have less noise. If not, your software is not up to that specific task.

Using the camera JPEGs here will lead to totally wrong colors, banding etc. due to all the "optimizations" applied to the RAW data in order to get good looking JPEGs.

At the end of the day the goal is to take a picture and to expose for that specific subject and the sensor noise may actually be low enough that you are satisfied with the exposure suggested by the spot metering of the camera. In that case you can directly use the camera JPEGs and be fine. Heavy postprocessing is only for low volume activities or people with too much time.

I work 24/7 but still process my pictures to my satisfaction. Guess I have enough time for what I WANT in life.

Oops...I made the erroneous assumption that anyone reading the LuLa article and basically subscribing
to the ETTR mantra would be shooting for RAW capture and...doing his own PP.  My bad!     ::)

:) :) hahahaha

EOS Bodies / Re: POLL: How many mp do you want anyway?
« on: January 31, 2015, 06:25:19 AM »
I wonder: ???
If many here want 36 megapixel, why D800, D810, A7r are not big sales successes? ::) :-X

I do not know if they are successes or not, but if they were utter failures, there is no way Canon would be coming out with 50 mp camera.

Not excited.  ISO 6400 camera is not for me.  Where is 5D MK4?

Really? Hmmm

The true specs will decide but looking at those specs it's very meh.

Beauty is in the eye of the be holder - I'd get one in a flash.

Me too… Will order as soon as I decide between the S or normal.

Ugh so I'm gonna have to buy two cameras this year? One for portraiture and one for events?


You already have one for events. Did your 5D3 suddenly become useless?

ahahaha. well said!

Thanks Canon for this. But it took you approx 3 years to figure out these issues? Really?

Congratulations. Love his smile...

It seems like you do not need the 1dx. I think a cheaper, smaller camera will be more appropriate. Am going by "need to save money for vacation."

This is good. Right?

Until they step into 2012 and put 4k RAW video in the cameras... I don't care. Even GoPro has 4K footage now... Canon is turning into the Apple of the camera world.. forever playing "catch-up."

I sold my 5Dm3 last year and moved to RED cameras. i WISH they'd make a 4k RAW camera so I could pick one up for backup.

You don't shoot stills right? 5d3 is a stills camera. A very nice stills camera.
