Two Versions of Half Dome



Composite of 7 photos



Tri X 400 composite of 4 photos



I seem to be partial to the B & W


Both taken from Glacier Pt. within 15 minutes.

Both are very nice, Dan, but I also prefer the B & W image. A little more contrast in the sky to show off the clouds (or some more dramatic clouds) would have made the B & W shot even better than it already is.

The color version seems to have a blueish cast to it, and the horizon feels just a little tilted, making it just a tiny bit uncomfortable to view (maybe it's just me, others may not even notice).

I was wondering if you can explain a little bit of your process for creating the composite images, and why you chose to use the technique to record this scene. I ask because I am curious and also because I am not familiar with the process.

Thanx Warren, this is my first attempt to use the stitching process in PS with a Tilt Shift lens (24mm in this case).

The compelling reason to do this is to create a file that encompases more than your lens would capture, I believe the 24mm captures 84 degrees and the digital images cumulatively are close to 168 degrees. I also added in images of the foreground via the tilt function. I believe that the curved horizon is a result of pushing this perspective, but I will have to continue to play with this. If anyone has any perspective on using a tilt shift lens your expertise would be most helpful.

The B & W is closer to 110 degrees without any tilt.

In the past I have created panoramas using a tripod and moving the camera. Obviously this changes the relative perspective of the sensor or film to your image and you must crop significant portions of the image in order to create a controlled panorama. So essentially you shift the lens ( by several degrees for each shot total of 24mm) not the camera to maintain the same angle of the scene to the sensor or film. You then stitch the sequential scenes together in PS.

I think I pushed the envelope on the digital, but I believe the lens at this point has more potential than I am getting. There is a twist function that I am just starting to play with and it changes the depth of field wonderfully. However, I am not anywhere near being able to stitch those types of images together at this point.

Trial and error. I am working on some more panoramas and will post for feedback.

BTW I believe you mentioned that you took some photos at
Bodie, can't find them on the Blog, but will be posting mine from the trip last week.

Thanks for explanation, Dan. I forgot that you recently acquired that tilt/shift lens.

I posted a few Bodie pictures here. I have more that I have not posted, of course. I'd love to see yours. The blasted Blogger search function is still now working. The search function in "Edit Posts" works, however. Go there and do a search on "Bodie", and you'll find some.

ooo, that looks like an awesome place! i prefer the first shot. the valley really makes the size of the half dome look way more impressive in size. also, the valley alone is very interesting to see. the shadows cast in it add depth and create space.
