Re: What DSLR Improvements I'd Like To See

Of course its a lens aberration.  But I think she thought that it could 
be corrected post capture.  And what I replied was that I didn't think 
that the software could do something like this.  Although if you knew 
exactly the what the aberrations were for this particular lens sample, 
you might be able to do something.  Hopefully the visibility of these 
types of aberrations in digital will force manufacturers to produce 
better lenses. :)

How bad have these aberrations shown up on your starkist?

2. Better software for chromatic aberrations This is where I am really
ignorant. But it seems to me that good interpolation (?) software might

distribute

the results of chromatic aberration better, so that digital apes film

more. I

mean, people are not going to be happy when they discover that one half

of

their lenses do not work that well with a DSLR. I wouldn't be happy

shopping

around for older lenses, having to find out which one had bad effects on

a DSLR.

Interesting concept, although it would probably be relatively difficult
to determine what is a chromatic aberration versus true adjacent color
deltas.  If you did a blind blend while preserving luminosity, it would
eliminate some of it, at the cost of general color "softness" (I'm not
sure what you call this).


I had always though that chromatic aberation was a lens deficiency.
Blaming a lens problem on digital capture seems like shooting the messenger.
The answer is lenses that are better corrected for chromatic aberation,
though this may mean compromising some other lens defect.
