That's easy then. Have a look at: https://www.howmuchblur.com/ https://dofsimulator.net/en/ A bonus point: the site I already mentioned when we talked about the choices for the circle of confusion. ...

There is a difference between (1) being able to see blur in some parts of the image while viewing the whole image under the normal viewing conditions (limited by the resolution of the human eye)

This is rather patronising. No, it is not "the same". I clearly said that the two images will be completely different . Two images can have the same DOF (50 cm, for example) and be completely ...

Well, all DOF formulas I have seen depend on the product "Nc", the f-number multiplied by the circle of confusion. To me this means that reducing c by 20% (cropping) and simultaneously increasing ...

That's impossible. Cropping always reduces DoF. Stopping down always increases DoF.

It does. The CoC is about twice the pixel pitch. There are some DoF calculators that give the user these two options too: https://www.dl-c.com/DoF/

Focal length? It is supposed to be image diagonal. The actual image size does not matter. If you go to an art gallery and walk up and down to paintings of different size, you'll find that all ...

No, it is not. The point is that DOF can be changed months after the image was taken simply by cropping the image. Croping changes field of view and depth of field. Obviously you can change DoF by ...

I don't know. I woud say in any practical terms the sensor size and the megapixel count are petty much irrelevant for macro photography. If my calculations are correct, because of diffraction, ...

I don't understand the purpose of this thread. What bias are we talking about? Some sensors are bigger than others. Some sensors are smaller than others. It is a fact.

Not even that. This is not a discussion about portraiture. The OP clearly says "whatever you are taking a picture of".

I am. Was hoping that Gary from Seattle would finally get it. Gary, if you pick 20 lenses tested on the same m43 body and make a table of their MFT50 score, they will all have about the same score ...

I feel pretty comfortable taking a picture of a ladybird from about 10-15 cm away. Not so much if it was a tiger... I suppose for every subject one might have a preferred shooting distance. For ...

Aperture is a hole. Depending what adjective we put in front of word "aperture" will signify how we quantify the size of the hole. If I remember correctly: Physical aperture (iris, diaphragm) - is ...

Hmm... Not sure this beats Auto. I think I'd need a different hat for different lighting conditions. https://en.wikipedia.org/wiki/Exposure_value#Tabulated_exposure_values

And that's exactly what I wanted. So far about 100 DPR members expressed their opinion on why they prefer setting aperture manually. The population I would like to access is photographers who ...

Thank you everyone for voting and commenting. The numbers undeniably confirm that most photographers do care about DOF. More than that, more often than not most photographers prioritise DOF over ...

Looking in the manual (sorry, I'm not familiar with Canon) there are quite a few options related to the autofocus: Face AF, Tracking AF, Servo AF etc... Might be worth testing them before the game ...

Whenever there is a poll about the most used exposure mode, the top option is always the Aperture priority followed by the Manual. People clearly prefer setting the aperture themselves. Why? I ...

What other options do you have? There is no scene selection mode called "Sport", no manual exposure, no manual focusing according to https://cameradecision.com/faq/is-the-Canon-PowerShot-SX400-IS-g ...
