Depth of field

I love this Picture.  The really narrow depth of field makes the flower seep to pop off of the photo almost like 3D  I took this with my Canon XTI and 28-135 lens.

F-stop.  f/8
Speed.  1/250 sec.
ISO.     100
Focal Length.  135mm
Subject Distance 400mm

The Minimum focal distance for this lens is published at 500mm.  I am able to get focus confirmation at 400mm with my copy.  I wonder if other 28-135 Lenses are the same. I

This photo was shot in Raw.  Cropped square and converted to Jpeg.  no other editing was done.

A Photo of Mine.

I took this photo in the early evening just before the sun set.
Photo Specifics:
Camera: Canon XTI
Lens:  Canon 28-135
F-stop:  f/5.6
Exposure time: 1/30 sec.
ISO: 200
Focal Length: 135mm

I shot this Photo in RAW and then processed it in DXO.
After setting the color to Black & White i used the Film Pack Plug in to simulate Ilford HP4.
I applied a yellow filter to lighten the flower then added a vignette to darken the other flowers.

I really liked this photo before I played with it but the black and white version has a nice quality.
I plan on going back to the garden where I shot this with my Elan 7 and shooting a similar photo on film.

My goal is to try and match this as close as I can in the darkroom using analog techniques.  this may take a while as family life is very busy right now.
