Re: Portrait help, please?
I might have remembered this wrong but when I was at school I was told that dof is both in front and behind the point of focus, and to focus behind the eyes.
Now I do know this lens suffers considerably for edge sharpness at f1.8 but recovers quickly but since I work it all out for landscape don't do portrait only remember it is above nyquist over the whole sensor at f5.6 and best at f6.3, I think f2,8 should give reasonable edge sharpness and dof and I suppose I could find it out but just looking at the photo gives me confidence.
In fact I will work it out; f4 gives 0.24 metres dof at 2 metres distance, f3.3 is 1000 LW/PH approx at the edges but sharp in the middle which is all you need. So I suppose iso 200 or maybe 400 and job done. :)
At 4 metres you have about a metre do at f4, I'm not very good with judging distance from a photo. :)

William, your candids and portrait are lovely. What a good idea to provide a photo essay of the day. I hope you don't think I was upset with the crop! It just struck me as a little funny, actually, because it looked like she was posing sans dress. It's just my warped sense of humour:)
TC!

Hi Steve,
The DoF DOES cover both in front of and behind the focal point, but not by equal amounts. 1/3 in front & 2/3 behind is as good a rule of thumb as any (unless anyone has any better rule, short of a DoF calculator on a iPhone).
So by focusing on the eyes (which are the most importnt part of any portrait) - hopefully - the DoF covers things nearer (like tips of noses, chins etc), and things further away (like ears).

That reminds me of my #1 studio joke ...
Just about everyone who see it makes a comment of "Oh yes ... I know what you're shooting down here ... nudge nudge, wink wink" (referring to naked women). I assure them that it just never happens, and then add "We would, but we just can't find any willing women ... they're too smart for us"!

I did not know if you were having a joke, or if you would not choose to do that because it looked like the Subject was nude. I tend to generally write and read on forums: literally.
But it doesn’t matter how I interpreted your comment as I did not take it personally, but rather took it as an opportunity to further develop the thread and discuss another point.
Obviously there will be Clients (from my perspective) and Parents (who take Portraits of their Children – like you) who would feel that going is too tight on the crop gives the impression of a nude pose; and therefore would be reluctant so to do.
I was merely pointing out that the place the image might take within the whole coverage or as part of a Collage can have an influence on that perception – and also by providing the two samples, give ideas as to how that could be – and also show other ideas as to how “Prom Photos” might be addressed.
I now understand your humour and understand that your comment was a joke, thanks for explaining: and certainly don’t feel that I was upset in any manner – I was not. Participating in this thread has been most enjoyable, your efforts and the rapidity with which you have applied the knowledge gained is most impressive. This is a credit to you and to everyone who participated – we all take something away from the table here.
Good luck with your Photography: IMO you have talent and a brain and a willingness to listen and extract information which is useful and relevant and then try things out and then regroup and try again – this thread and your efforts show that wonderful images can be made with an inexpensive Prime Lens and a Prosumer DSLR . . . others can learn from that as well as extracting very useful information along the way whilst reading through.
I hope your Daughter enjoyed the Evening.
Thank you for the kind comments on my work.

So by focusing on the eyes (which are the most importnt part of any portrait) - hopefully - the DoF covers things nearer (like tips of noses, chins etc), and things further away (like ears).
In this regard another rule of thumb is to focus on the leading eye.
Taking the Collage above and numbering the nine frames from Top Left and then Left to Right across: In Frames – 5; 6; 7; 8; 9, the Plane of Sharp Focus is through the Subject’s Leading Eye (“Leading” means closest to the Camera).
The only difficult situation apropos this “Rule of Thumb” in those nine images was Frame 3 - where I needed to get impact through the extended arm as she was choosing the hair clips.
That frame is the result of a compromise on the run, as my first intention was to get her face and arm in focus – but I was at F/4.5 and already at ISO1250 and I did not want to go higher ISO.
I was pulling 1/320s. My Tv (Shutter Speed) limit in this situation is about 1/250s to ensure no Subject Motion – so even if I dropped to Tv = 1/250s that only would give me ⅓ more Av (Aperture) and that was not enough to get the adequate DoF I required.
I was shooting a 24L on a 5D at about 3ft SD (Shooting Distance) and I knew to do what I wanted and to stay at the same low angle, and close to the Subject, for the feeling of intimacy and involvement and also lead the viewer's eye along the Perspective of an in Focus Profile and Arm: I would need about F/11 . . . there was NO WAY I could get to F/11
So I do know that DoF gets larger as the Plane of Focus gets further away from the Film Plane - but I did not want to move further away from the Subject – so as she was expending her hand for the second time to choose another item I refocussed on her hand and move up just slightly, to catch the mirror with the knowledge that her RELFECTION of her face would be in focus . . . and I used that shot and not the first.
I was just lucky that Girls generally take their time choosing things and most often need to pick them all the items up and have a close look at each item . . . had she not looked at that second hair clip, the Collage would have been different, because the first shot I pulled I knew was wrong as soon as the Shutter was Released – and it was destined for the Cutting Room Floor – which is where it went.
Incidentally, I chose this particular Collage as a sample for this thread, because (except for Frame 9) all are shot sans Flash, which is generally how I work.
