    No, no, not back - forward. You need to be closer to the bench. Like 3 ft top, maybe less.

    Well, it isn't exactly a bench. And I didn't exactly follow the rules and take two shots. But I went out to shoot this assignment and had a ton of fun shooting with my 50mm at f/1.4 as close as I could get to things. So this assignment resulted in (among other things) ... DOF Dog:

    [Sorry, guys if this is just too off topic. It really wouldn't have happened without Nik's assignment.]
    If not now, when?

    Larry beat me to the punch yesterday...I thought about shooting my Black & Decker Workmate on the way home from work yesterday. I go to the computer and open Dgrin and Larry posted his workbench..good idea Larry>
    Here is my B & D Workmate...I hope I did this right I am just learning how to use this DSLR.

    Thank you for the entries! thumb.gif
    It looks like your second one, f/10, suffers from a hand-hold blur.
    To avoid that, you need either more light, or higher ISO, or a tripod rolleyes1.gif

    Yep..
    I left the tripod at my-in-laws out of state so these were both handheld shots. My question is "is this the right concept for the technique? Was I to only adjust the apertue? I adjust apeture and my focal point..after re-reading the directions, I think I should have had a tripod...focused on one spot and then adjusted my aperture. Does that sound right?

    What you could have done also to avoid blur is to crank ISO a bit. Since ISO/shutter speed do not affect the DOF *at all*, it's OK to adjust them. You'll get maybe a slightly noisier shot, but not by far.

    Other than that, yes, your techniques was precisely what was required - focus the camera to the same point and take two shots, one with min aperture, and another with the max one.

    Hope to see more from you, if you have time:-)

    I just received my 50mm f/1.4 from BH Photo and this assignment looked like a perfect test case for it. The perfect lens for dramatic differences in DoF is wide and fast. 50mm is as wide as I go in fast lenses (on my full frame 5D it is, of course, it is wider than it would be on a 1.6 crop body), so here we go:

    Shallow DoF (f/1.6)

    97260383-L.jpg

    Deep DoF (f/22)
    97259528-L.jpg

    The focus point in both images is the leaf at the far end of the near bench which is about 10 feet away. The hyperfocal distance for 50mm at f/22 is around 15 feet and as a result as you can see the trees in the far field are still somewhat out of focus in the stopped down image. When looking close up (not visible at this scale) the whole image at f/22 is somewhat soft presumably due to diffraction.

    I learned a few other things about my Canon 50mm f/1.4 while studying these shots. The lens is very soft at f/1.4 but sharpens up quite quickly as you stop down and is very crisp by f/2.0. The lens also vignettes significanly when wide open. I corrected both these images with DxO Optics which cleans up the vignetting quite nicely. DxO Optics also signficantly improves the sharpness at f/1.6 and f/1.8 but still leaves the images lacking somewhat for contrast (most noticably at f/1.6). In practice I will try to avoid using the 50mm at apetures wider than f/2.0 and consider opening to f/1.4 only as a desparation measure.

    Congrats on a (great!) new lens and a nice entry! thumb.gif

    It's awesome that you get to know your new toy and realize its cons and pros for yourself (and the rest of us). :):

    I also think the difference between the shots would be more dramatic is you had got closer to the bench and focused on its nearer end rather than farther one, don't you agree? headscratch.gif

    I happened to find a shot I liked that was just a plain old bench, so I thought I'd post it up. :):

    Sorry I couldn't go up to f/22...it was raining and I was w/o tripod. ne_nau.gif I thought f/8 still did a good job of distinguishing the DOF though. thumb.gif

    Thanks. I was quite happy to see my results with the 50 match the review I read of the lens before I bought it.

    I gave that a shot and it is definitely an improvement over the orginal shots. However, I did have to slightly cheat on the rules and push the focus point out bit at f/22 to sharpen up the background. Both of these shots are manually focused.

    f/1.8
    98015358-L.jpg
    f/22
    98020578-L.jpg


    I then spent some time playing with other approaches to the scene. This pair were shot at 200mm and do a better job of capturing the essence of what drew me to those benches in the first place. Getting this much DoF with a 200mm proved challenging. The 200mm stops down to f/32 which helped but I still ended up taking a series at slightly different focus distances and picking the best compromise.

    Just in case you're looking for a bw treatment for the LPS... I think this image could benefit from a more agressive b/w, since the current one looks a bit flat (to me, that is). HTH iloveyou.gif

    I'm always looking for more aggressive treatments, so feel free to expound on that =c) In fact there is a picture of somebody's dirty hand that I sometimes see in the ehader, that I would love to find out the way the PP was done.

    If I remember correctly, we were all high on Draganizer at the time, so it's very likely he used that action. Google for it or search dgrin or dpreview.
