But you lose important details,color accuracy & other things by increasing the ISO to the roof.
The "mood" of the noise is a fake judgement...if the shutter allows you,it's better to use lower ISO-s & add the noise later
This way,your details will be preserved & you can also control the quantity & quality of noise you need for that photo's general mood.
I am not an expert on this, in fact i am just trying to be the "beholder, in who's eyes, lies the beauty"
I agree that controlling the quality and quantity of any picture is the more appropriate way to take a shot. I deliberately used the term appropriate. As there are some basic guidelines but no right and wrong in photography. Besides, how do you define Control, in photography. If by control you mean taking crystal clear and sharp pictures. With all due respect, i disagree. I will humbly ask you, how do you define "Shallow depth of field". Focusing on one small portion of one object and leaving the rest out of focus no matter if the surrounding is beautiful and full of natural vibrant colours....... well people goes like "Wow" on that DoF effect. Photographers don't only buy f1.4 or f1.8 lenses for their brightness, they always speak about how creamy is the bokeh.
How do you define bokeh? One can say that it's a flaw. But then we will disagree that it's not.
Did the person who invented camera/Lens, printed in the manual that "Dear Customers, with this equipment, you can take crystal clear shots and you can also mess up the 90% of the picture and still feel happy about it. Or did they say that buy this lens instead of the other bcoz this one creates much more mess. LOL"
. With all due respect Razvan, we even invented a term for that mess i.e Shallow depth of field
and we all call it a Technique. We all call it Art. I can go one by one on B&W, Sepia, and other filters. Keeping in mind that we are not bound to shoot in B&W or Sepia, but we do and we like it. Why do we appreciate the B&W when we have the ability to shoot in color? Why do we soften the skin, why do we use healing brushes? And don't forget, there is infra red photography too. LOL Who on the first place, defines these as techniques
. Nobody has the right because everybody loves to think out of the box. Nobody is bound to follow only. We only take inspiration out of other peoples work. And that is enough.
You mentioned that by increasing the iso, important details and color accuracy among other important things will be lost. Well, "If the shutter allows" then why would one put himself into trouble of self introducing the noise by increasing the iso on purpose, and i am saying "On purpose" (though, i honestly don't care if someone is getting their desired results) In my humble opinion, it's all about that moment when you see an opportunity for a shot and you take it. Composing it the best possible way you can. If the light out there is not enough... and that particular moment is going to be over, you are not sure when, what will you do in such a situation? Well you wont set the iso at 100 bcoz you know that you will miss the shot. Check Bjorn's shot again. His main subject is the man standing in the middle of the picture. Look at his stance, his face, his whole body language. He is unaware that he was being spotted by a photographer. Now comes the surrounding... Light is poor and you can't use the flash. What will you do? If I were you i'll capture that moment no matter what. Of course i'll do my best. Bjorn's composition is truly wonderful considering the circumstances. If it would have been an indoor shot, with someone lying on the couch. Then it would be fair to criticize Bjorn for needlessly raising the iso and introducing noise, when he could have preserved the details and could easily introduced the noise in PP. No such shot is in discussion to be called as fake judgment.
I am unable to understand what you said in the second quote. "The "mood" of the noise is a fake judgement...if the shutter allows you,it's better to use lower ISO-s & add the noise later"
you are calling it a fake judgment and conditioning it with an "if". Well, that "if" is the only reason behind every action, taken to get the shots containing noise. If you know what i mean. I think this post is getting longer. Just take it as a discussion not a debate. I am a novice and you are an experienced photographer
My only intention is to learn from you guys. I apologize if i didn't make myself clear enough. I hope you will humbly point out my mistakes.
