p.1 #1 · p.1 #1 · Canon 5D MkII Bracketing for Depth of Field


Hello, I shoot product images almost daily, and I usually shoot a variety of apertures to get differing depth of field.

I would love to be able to simply hit the shoot button once and have the camera automatically vary the aperture from say, 2.8, 8 and 22 and take a shot with each aperture. So, just like bracketing, but varying the aperture.

I can find no way to do this, but I assume there are many people who shoot products and would require a similar work flow, surely this can be done? Any advice greatly appreciated.

I believe Magic Lantern supports this.

I'm not aware of any Canon body that supports "aperture bracketing", though I've never owned a 1 series DSLR. Perhaps there is a 3rd party remote/tethered controller that can support such a thing. I do think it is a good idea though. I believe there are 3rd party remote controllers that can "focus bracket".

If you vary aperture then you must adjust either ss or ISO which would introduce other issues such as motion or noise. If you want the best results shouldn't you leave the exposure parameters alone and use live view to focus at different point over several images? You can then use a program like Helicon Focus to combine them.

Focus bracketing is what you want, not aperture bracketing.

Magic Lentern has it, and there is a pc based software called Helicon that does it as well.

There may be some smart phone aps, but I don't specifically know of any.

I shoot on a tripod, so I manually vary the aperture (I shoot aperture priority) and let the camera adjust the exposure accordingly. I do not understand why bracketing for aperture is not a stock standard feature on all Pro/Semi-Pro cameras.

RE Magic Lantern, I can not find where it says it features this option and it seems to be a LOAD AT OWN RISK option which I am not comfortable with to be honest. But thanks for the info just the same.

That is not what the OP wants. I’ve manually “aperture bracketed”, what the OP wants is an automatic “aperture bracket” with a single press of the shutter.

I simply shoot three different apertures, and then choose later which I will use for my needs. I do not combine anything, simply a matter of choosing at a later date, which depth of field looks right.

Thank you, it does in fact seem like it does do what I want, just have to get past the 'risk' factor....

I would like semi-automatic focus bracketing before I'd have much use for aperture bracketing.

An option to set 3 or 5 focus distances and then click the shutter once to have the camera shoot them as quckly as it can.

I understand what you are asking for, but I'm confused as to why you would do this or what you are trying to accomplish with this technique.

Another "way" to get the DOF you want, is to buy in TS-e lenses. Sure there are compromises, but so does stacking.

Dan, I shoot products for my web site, but I prefer a stylised shot at times rather than an 'all in focus' shot, but depending on what I am going for, I may like a shallow depth of field or a really shallow depth of field.

Some examples of the shooting I do is here: click here

The above are fairly standard, but when I want the varying depth, it is for a result such as the banner graphic on this page: click here

The above shot was taken three times at f4, f8 and f16, and I choose which I want to use later....

If you are in Tv mode and bracket isnt it the aperture that gets changed?

If you manually fix the ISO then yes - otherwise it can change aperture and/or ISO.

Ah true you will modify the exposure.

Perhaps if the lighting is constant you can record the same values to C1-3 apart from e4xposure/aperture and shoot one of each?
