[LRflex] Intro - yab

Everyone,

Before adding to the thread Xavier Bille started on the 24 Elmarit, I probably 
should have introduced myself.  My name is Bill Holtz; yab, yet another Bill.  
I am from St Louis Mo and have belonged to this forum for some time.  I seldom 
post but I really enjoy the international flavor of this forum and I get 
inspiration from the posted photos; you guys do good work.

Some time back I contacted David Young and asked him for info on a Nikon 
scanner he had mention in a post.  He kindly replied and requested I show some 
results.  I did get the scanner and I thank David very much for the information 
and his encouragement.  I am still on a learning curve as my results will show, 
but the scanner was just what I was looking for.  Then when I replied to 
Xavier’s post on the 24 Elmarit, he too requested that I post examples of what 
I was getting at.  So, I have placed a couple of albums on my web site 
www.williamholtz.com in reply.  You will note that my site is  intended only to 
share photos between family and friends.  I am a bit more amateur than most of 
you; read that to mean you won’t confuse my bird shots with those from Doug 
Herr.

Xavier, as added explanation, I realized problems using the 24 Elmarit on my 
20D when I tried to make a stitched pano (I failed miserably).  When selecting 
tie points at full resolution, features on the edge of one frame would be 
toward the center of the adjacent frame.  The problem was obvious.  What I 
called CA is probably not Chromatic Aberration inherent in the 24 Elmarit but, 
as Keith Longmore explains very well, induced by using a wide angle lens not 
designed for a digital sensor.  I show two examples of this in the first two 
rows of the album.   In spite of this I do still use the 24 on my 20D as shown 
in the bottom three rows.  It is the widest lens I have, it is good for street 
photos (I think its performance is better in the close range), and I use it for 
snap shots through a window of a moving vehicle (where optical quality is not 
important).

Bill
