How much DOF do you like?

Hi,

Yesterday, when I looked at my pics from the afternoon, I found a burst of pics from my dog with almost identical photos, except for the aperture setting (and the obvious consequences ;-). Of course, I know all the DOF comparisons with boring objects, but now I had something from the real world.

And while it is obvious, that the one at f2.2 looks more artistic, I am not completely sure, which one I like more.

What do think? Is it a clear case for you? Do you have similar comparisons, where you feel unsure? Would be interesting to see other examples.

Thanks for watching, please feel to C&C.

It's all personal opinion. It depends on the back drop, subject, and how much you want in the scene a long with the lighting.

Personally I prefer shot #2 at F4 as it introduces just enough of the background.

I think that the whole *lets blow the background out with a fast prime no manner what* mentality and style of photography is over rated.

The best shots that I've seen are from photographers that know when depth is appropriate and when lack of depth is appropriate to what they're trying to portray in their photo.

why f2.2 on the 135?

put the aperture on F2.0 and leave it there!

Actually looking at it again I like the F10 photo the best. The background really compliments the subject plus it's exposed correctly.

Nice idea for a thread!  For the particular photo you posted, I think a little more DOF than the f/4 pic would be my favorite, so I vote for f/5.6 for this particular pic.

That seems a bit boring fur sure...

although  it is fantastic at f2, limitation is rarely a good strategy...

no, I have the shot at f2 as well, but the one at f2.2 looked similar, but the dog was crispier. Will check again tonight. Before that, I had a high aperture setting to get more DOF when the dog was running. And while taking this series, I saw, that I was till at f10 and just turned the wheel down to decrease the aperture number, and by that, I obviously  stopped at f4 and f2.2 for a shot. I will check, if I have one at f5.6 as well.

Re: How much DOF do you like?

#1, then #3 and then, far off, #2.

The semi-mid-aperture in #2 is far too nervous in my opinion. I prefer it rather more blurred, like in #1, or - if not possible - then crisper, like in #3.

Perhaps f/5.6 had eliminated some of that nervousness?

My problem with #1 is that the dog almost looks as if it were shot separately then photoshopped or tacked onto the background since the background is too blurred. For me, f/4 up is nicer with perhaps f/5.6 or f/8 being possibly the best.

Its good wide open but the 135L is that bit sharper at f2.2 and there is less CA.

Yep - that is an effect you risk with the very narrow DOF.

Before we had PS, the reaction might have been, "Oh, extreme subject isolation!"?

For me, f/4 up is nicer with perhaps f/5.6 or f/8 being possibly the best.

I would have liked to also see a f/8 shot. The f/4 is, as mentioned, too nervous with branches almost outlined in double.

Very much a matter of taste, though. And, I openly admit, I like blurred backgrounds

Re: How much DOF do you like?

Out of the the three, f/10 is my least favorite.  Your dog just starts to blend in to the background on that one.  I'm going back and forth on whether I like the f/2.2 or the f/4 better.

f2 and leave it there? Not for me

In my opinion, too many people shoot ​wide open​ and nothing else. You get nice bokeh for sure which is the lure of that method, but what you end up with is important features of the subject out of focus.

I like the f/4 shot because you've stopped down and I can see most of the dog's body sharply in focus. As others have said you could probably stop down more and still have great isolation of the subject from the background.  The f/2 shot doesn't keep the entire dog in focus and that takes away from the photo IMO.

well, I take a different view.

the shot is about the dog - you have one of the best bokeh F2 lenses in your hands, what is so meaningful about the trees that should detract attention from the dog

carry a T4i and 15-85 as a second camera if you want shots with deep dof - the 135 is about one thing imo - isolation and bokeh

for this particular shot no 3 is the best...other situations may dictate a different answer though!

I agree. This is why I obviously lowered the aperture number. It just happen to have that I exported the f2.2 shot instead of f2. But you can find the f2 shot now in my previous message at the bottom of the thread.

!! Don't overdo it. The shot I showed was at f2.2 with a 5D, not from a P&S. !!

I just wanted to see people's reaction on my thoughts and going through the answers, there is one thing very obvious:

People have different opinions, which pic they like best... so, well, the question was maybe worth it?

This!  Now you're cookin!  

Nothing should detract from the dog!  The shot is about the dog!  The bokeh and blur backdrop are great, "not to distract our attention", and to bring our eyes to the beautiful dog!

Good Work!

As I said, use a different zoom lens for deep dof so you can frame deep dof shots.  For Portraits, F2, F2, Only F2

I have 5d and T4i btw.  T4i is not a P&S -- for deep dof shots, it does just as well in good light with zooms.  Use Zooms for deep dof shots, then you'll be able to better frame.  The F2 of this remarkable lens on FF should not be wasted on anything but F2.

Kind of shows how silly we all are.

f4 vs f2 (two stops) and there's barely a difference.   Funny.

Yes, you are right, but you know, what is even more fascinating than our silliness?

The fact, that the combination of human eye, brain and trained/evolved/acquired/... aesthetics perception makes it possible that we actually DO see a difference and feel that it is not negligible and even worth talking about...

But hey, you are right, nothing feels as real as to pass my hand through the soft fur of my dog, and feel the warmth of his body... Not even with a FF at f2....
