  • Or the late 50s-early 60s when I wandered around up there.  Many of the trails were filled with white pumice that made it like walking in sand.  Beautiful country though and swimming in Spirit ...
  • Thanks Cliff.  I shoot mostly handheld panos but am now starting to play with HDR.  I find that a single image is usually sufficient for the Sigma cameras as long as the light is manageable but it ...
  • Replied in What about wind?
    How many windless days or shots with adequate shutter speed can you plan on? What is the best hdr software? Mike
  • Every situation is different with fill light even when photos are taken in exactly the same conditions fill light may affect them differently.  I usually start by dropping exposure then add no ...
  • I wonder if you couldn't almost duplicate that processing by simply reducing exposure and using fill light to bring the exposure back up in the non sky areas in spp.  The processed image looks to ...
  • Replied in entrance pupil
    For closeup pano shooting the entrance pupil of the lens being lined up with the center of rotation is critical to avoid parallax errors.  The further away the subject is the less it matters. Mike
  • Nicely done Tog.  did you sew that bag bellows yourself?  I made one using neoprene and neoprene cement from the local dive shop.  It's really hard to make anything small that still allows all the ...
  • Sounds interesting. Mike
  • With the DP2M you need to use spp 5.5.  spp 6 is for the DP2Q. Mike
  • Probably will not work with the 12-24 on SD1 because of the focal plane register. Also the Sigma image looks like it is shift only. A better solution is to buy a canon 17mm ts-e and either convert ...
  • I use this.  The side part blocks the sd card slot but I'm sure it can be safely removed and will probably do so when I return home.  I doubt a custom bracked will be available unless some sigma ...

    I do kind of like how it turned out too. Mike
  • I bought an RRS universal small L bracket years ago that has been on all of my Sigma cameras over the years.  It is currently on the quattro but gets moved to the SD1, DP2M and the Sony A7r.  It's ...
  • Yes I have a pano head consisting of an acratech head with a rotating base mounted upside down to serve as the horizontal rotator. On that is a sunway rail dmc-200L with a Hibu BWG M1 as the ...
  • Turn on the camera and change the focus to manual without touching the shutter button to cause it to af.  I think that is the same in the Merrill. Mike
  • Created discussions Quattro in Seattle at night
    First a pano of Seattle downtown. Shot at iso 125 f5.6 10 sec manual focus to infinity.  A little splotching here and there but overall not too bad.  Of particular interest is the difference in ...
  • A shot of my memory card on the mac when I got home tonight: Mike

  • These are the goto guys in the professional area.  Most of these conversion lenses were designed for much smaller sensors but now that sony is offering both full frame and aps-c videocameras maybe ...
