EOS Bodies - For Stills / Re: ISO 50
« on: January 23, 2013, 05:51:02 AM »
@ Neuro. Ok I now learned that no matter what ISO is selected, the sensor collects equal amount of light but processes it differently depending upon the ISO setting.
Cool.
Thx.
I have not yet pieced it together in my mind how this causes blown highlights at 50 ISO, but since I do not intend to use 50 iso anymore, I will let this pass... Why bother taxing my not so technical mind...

This may sound simplistic but the ISO choice for me is the minimum to get the job done.
Getting the job means getting a non blurred photo of the subject in the light. ISO selection may be very high but if that is what the photo requires, that is what I put. I cant not take a picture just because it requires higher ISO than what I find pleasing.
If me or my client is picky about the noise then I need to get wider opening lenses and cameras with high ISO capabilities. Even then lowest ISO principle applies.

To be blunt, you can safely ignore the drivel that Mikael is spouting about changing ISO somehow affecting the amount of light or number of photons hitting the sensor.
[/quote]
Even a child will agree that the amount of light hitting the sensor depends only on f stop/shutter combination. No dispute.
But what I am questioning is that if changing the ISO did not matter, why do we bother setting the ISO? Why does the picture over/under expose if the ISO is not correctly chosen?
ISO kicks in only after the shot is taken, ok. But but it DOES kick in. So should it be factored in while considering the camera calculating total light for that 'click'?

In your test Canon does not look as good as Nikon counterpart. I hope Canon fixes this asap.
Confused about this. When I shoot I want to expose for what the scene demands rather than what my sensor is comfortable with. Don't u agree?
I don't, unless I'm shooting JPG. For RAW, I go for optimum sensor performance because the image will be post processed anyway and I need as much headroom / DR possible.
JR what does it mean to expose for 'optimum sensor performance'?
I expose for what the scene needs, as to what will make the scene look best. Eg if I am shooting a sunset I would expose for say the clouds and not the sun. Thx JR...

Why are firmwares not appreciated by some? Don't they make the machines work better/become more able?
Apple is constantly bettering their products via updates.
These machines are made by humans who release it as perfect as they can. Then they discover something that can better it and fix it for us.

Yeah but if I overexpose a little I quickly loose details in highlights. I do not like that. For my tastes I prefer preserved highlights and richer blacks.
But sometimes the blacks are too dark and I want Canon to give me a little room to open up the blacks when I want to without noise increase. I know it already does give me room, but to my eyes Nikon seems to give bit more.
No stress, life goes on, photos get created. But it is nice to know what the other companies are doing.

It is up to you or me how to handle large dynamic , but one thing is clear, it is always better to have large DR , you have more freedom, exposure latitude etc etc, I will close the link after a day

@Neuro:

It's only half the photons if the aperture is set a stop narrower or the shutter speed is set a stop faster.
[/quote]
And not if ISO is reduced by a stop? Does the sensor not reject half the photons when it is 'asked' to be less sensitive?
Dont pounce on me, am learning here...
I can easily see that the amount of light reaching the sensor is a function of shutter/aperture combination. But am confused after that. I thought sensor reacts to the available light based on what ISO is set.
Thx...

You need to put up pictures taken by me all over the room. They are not so expensive.
Your compulsion is evident. And I like it!

« on: January 21, 2013, 11:50:26 PM »I used ISO 50 a lot in my 5Dc because of how super smooth the files looked. The 5d3, not so much.

Could I explore and investigate this a bit further?
We, or rather I, by now feel:
a) I was mistaken about noise advantage of ISO 50.
b) ISO 50 causes loss of highlights.
c) I will not use ISO 50 again.
I examined the histograms of the two shots I posted earlier as test.
Although I exposed both shots equally, (And I cant be convinced otherwise) but the histogram on the 50 ASA shows that whites are clipping.... What does this mean? To my non technical mind it says: At ISO 50 the dynamic range gets reduced. Am I wrong?
I am not agree or disagreeing with many posts here, just exploring. Actually I do not even understand many posts fully to argue!

« on: January 21, 2013, 11:29:08 AM »Regardless of camera brand I often recommend using 'HTP' or whatever acronym a particular brand has chosen to signify a more gentle contrast curve towards the clipped highlights when shooting outdoors in sunny weather.
When I got my 60d I was shooting htp all the time in sunny weather, but stopped doing so because it increases the sensor's main weakness: high noise levels after raising shadows.
I admit clipped highlights are the worst thing that can happen, but it's closely followed by shadow noise - so today I only enable htp for jpeg and when I know the scene has a tendency to clip hightlights and I won't have to raise shadows in post a lot.
