Product Photography : How ISO Affects Depth of Focus

[theOlie]

i love how he starts talking about ISO and then just as you think he's going to explain it, he explains what the apature is all about. way to confuse beginners ...

[RyanTheTuber]

WHAT. This is so wrong...

Increasing the ISO whilst having a BIG aperture would only make the Shutter Speed REALLY FAST.

Please, beginners, head on to Flickr and join threads there. You get professional instructions from professional/hobbyist photographers.

I think Expert Village goes out and finds people that know as little as possible about a subject and then has them make a video. This guy is no expert.

@Stvkrn They don't ''has'' them to make a video. They FORCE them :D :D

So what happens if you shoot a photo with a huge aperature but really slow ISO?

[azenenc]

I didn't know what to do with the ISO when selecting settings for my photos, but I will pay more attention on the effect of the ISO from now on, probably in low light situations for DOF, I would try F16, ISO 800, and will adjust the speed according to the need, then I will use ISO 400, then ISO 200, and then I'll compare the results.

@azenenc what camera(s) do you have?

[azenenc]

@MrKaramjbara

Nikon D70 (very old but it's still better than many new digital cameras on the market today :)

thanks.....and i like your tutorial.....gracias amigo

In this situation an ISO of 200 or less would be ideal with a relativelly slow shutter speed and a big apperture.

It should also be considered the sensor size. Full frame cameras have much less noise and the difference between ISO 100 and 400 is neglible on said cameras.

this guy is just plain stupid

[kyandio74]

what a bullshit ...slow shutter , not slow ISO ...what a crap !!!

slow shutter ----high F-number= aperture

fast shutter ----- low F number aperture

ALWAYS try the lowest iso ...less noise .

only move iso up when you shutter speed is to slow and you can freeze the image even if the aperture is on the lowest level ...

[xjoncamposx]

I agree completely.

[SuperCheeka]

huh? I dont get it.

If you set to a large aperture to get a small depth of focus, you get more light in and, isnt it not true that you can now "afford to use a slower ISO setting? for a less noise.

:S

[xjoncamposx]

Large aperture = more light and less DOF.

Small aperture = less light and more DOF.

This video is wrong about ISO controlling DOF. A higher ISO only makes the camera more sensitive to light with the addition of creating more noise.

To get the shot this guy wants. You should use a large aperture and adjust the ISO + shutter speed to obtain the right lighting.

[babyalpha700]

i thought you could have just used aperture priority setting and then set the iso to compensate the overall exposure o.o? even if you have a slower shutter speed you still have the tripod to counter the vibration..

[birip0]

plz say it clearly.

[kutuzvn]

Why don't reduce the light by blocking it or move the light source further to get a better result?

[pkoicetr]

he is talking in general to explain...you don't have always that possibility, to control light or source of it, like in nature conditions.
