  1. I use both, and Paint Shop Pro is much easier to use and faster. So many people use Photoshop, it's hard to ignore, but if you are not doing more advanced manipulation (which Paint Shop Proc does as well), not having a large community to provide very specific advice won't be missed.

     

    But if you're likely to "graduate" to using advanced features, I'd go with Photoshop, merely because it sucks to be an advanced PSP user when all the talk/books etc are always Photoshop.

  2. Windows provides functions for filtering images when zooming in or out. Zooming in, the filtering eliminates aliasing. Zooming out it effectively softens to remove jaggies. You'll see this in Internet Explorer, and Office products like Word and Powerpoint.

     

    If you compare images at 100% zoom, they should look the same, since technically the filtering should have no effect.

  3. People like flo43c (Florinda Carter, 359 State Route 1748 E, Mayfield KY 42066, (270)-376-5470) should also realize that the "damn Internet" is not as anonymous as it feels.

     

    Maybe if they did, they'd be less likely to treat people that way and act like it's a free-for-all.

  4. If you want to use the actual steam, a quick blast from a hair dryer on your lens should do the trick.

     

    Lighting steam sounds fun (to this non-professional). I guess the issue is to avoid the steam stealing light from the tub

     

    Maybe shoot with and without steam so you can blend later and get the amount you want.

  5. Hard to see 'em but I'd go with Alder over Birch. In Washington we have a lot of Alder that look long, spindly, and weaker like that. My experience with Birch would show lower, fuller branches and a slightly thicker, more stately trunk. White Birch have a brighter, more uniform "peeling paper" bark.

     

    But I'm no tree expert.

  6. Steve, can I assume that that was the lower right corner? If so, the kind of aberration seem consistent with mine. Although I'd say mine is at least 50% greater in width. I don't know if the added saturation in mine is a function of the contrast or just more aberration and therefore purer reds and blues not diluted by the other frequencies.

     

    Is CA virtually undetectable in the center on yours?

  7. Jan, the CA in your shots indeed looks minimal. Note though that typical Longitudinal CA will appear most noticeably on tangential lines, or those that "face" the center of the image. Since the subject in your shot had lines at 45 degrees from that, the CA you'd normally expect is probably about 40% more than you see. But nonetheless your CA still looks great and I'd be delighted if my 70-200 looked that way.

     

    I called Canon technical support yesterday and described the issue. They concluded that it was a definite problem with the lens, so I sent it in for warranty repair.

  8. Andrew, I've tried Photoshop CS2's CA correction in the RAW import, and it doesn't get rid of the fringe. It only modifies it - i.e. yielding green/cyan/magenta fringe on different axes while reducing the red/blue. Your "100% correct CA" makes me think I'm missing something. Is there a trick to using the feature?

     

    I'm wondering if the Photoshop feature is designed to correct Longitudinal CA (colors focusing in different planes) and my problem is Lateral CA (colors focusing at different targets in the same plane). I suspect the latter because I have asymmetric fringing at the center of the image - that is, all red fringe on the upper left and all blue on the lower right.

  9. <p>I just bought a 70-200L 2.6 IS for my 20D and I've noticed what

    seems to

    be too much chromatic aberration in my shots. Comments from anyone

    experienced

    with this lens or problem would be much appreciated.<br>

    <br>

    What I'm seeing is red/blue fringe, even in the center of the image

    (4 pixels).

    In the lower right corner I'm getting 7-8 pixels of the same. The

    cleanest

    region is 1/3 up and 1/3 to the left of center, but even it has ~2

    pixels of

    fringe.<br>

    <br>

    With all the great reviews of this lens, I'm assuming this is not

    normal. I can

    see the issue in real-world shots, and my cheapo 55-200 II lens has

    less fringe than the $1600 lens does.<br>

    <br>

    <p>Are you seeing this in your 70-200L 2.8 IS? Any comments are

    appreciated.</p>
