    I'm using photoshop 7.0. I've been using the clone tool to clean up the
    sky in some old slides that appear to have become mildewed. Can anyone
    suggest an easier way to do it? It need not be print quality; just on
    line display. Thanks in advance, George

  2. Cool pic. Where was it taken?

    Using your image, I just did a pretty decent job by adjusting the curves so
    that all the colors in the range of the dark spots were turned up to white.
    Other than that, I would say just select the sky and add some fake clouds in

  3. Actually, I just ran the clouds filter where the sky should be, using white
    and the blue from the picture as my two colors, and the image looks perfect

    Select the entire sky and try the dust and scratches filter with a
    radius setting of 2. That gets most of it. It also tries to remove
    the wires from the sky which may or may not be desirable.

    BTW, if you wanted to hit both Photoshop newsgroups it would have been
    more appropriate to cross post rather than sending two separate

  5. 1. Select the sky with the lasso tool or the Polygonal Lasso Tool.
    Use a feather of 1-2 pixels.
    2. Run 'Filter - Noise - Dust & Scratches'. Radius 2, Threshold 7
    3. Deselect
    4. Open 'Curves', select only the blue channel and drag the curve
    down to get rid of that horrible blue cast.

    Next time, clean your slides BEFORE you scan...

  6. Thanks, usenet police

  7. Just a refinement: If you do not want to loose the blue in the sky,
    inverse the selection rather than 'deselect' in step 3.

    I tried to answer your question and politely suggested proper posting
    protocol and you come back with that kind of response. Grateful
    little guy, aren't you?

    And yes, I recognize it was his question, not yours. My mistake, and
    all the more reason to consider your response inappropriate. My
    posting suggestion wasn't even directed to you.
    Tom Thomas, May 5, 2005
  10. It just annoys me when people instruct others on what is "appropriate" to do
    in their newsgroup. If I crosspost to some related NGs, there are nerds that
    become furious. Then there are guys like you who think it is more
    appropriate to crosspost. Then there are people who don't think you should
    post to more than one place at all. And you arrogantly advise others as if
    you are some sort of authority on what is appropriate. As if it REALLY
    matters how the dude's message got into two NGs. Why does it bother you that
    he used a different method than the one you recommend? And if it doesn't
    bother you, why mention it in the first place, to assert your authority?

    And FYI, I make it my business because this is how I will always respond
    whenever I run afoul of someone like you.

    Pugnaciously yours,

    FWIW, personally I would prefer having the message crossposted, so that if
    somebody replies in the other group (to which I do not subscribe) I see it here
    and thus benefit from whatever advice is given. What benefit is there to posting
    two separate messages? I see at least one (considerable, to me) disadvantage.

    Thanks for all of the suggestions. I tried the cloud filter and it
    worked quite well. I also tried the dust and scratches filter and liked
    it even better. I think it looks more natural.

    There are legitimate reasons for certain Usenet protocols.
    Crossposting to relevant groups (on-topic) creates a single message on
    the servers with references to it in multiple groups. Posting two
    separate messages creates two separate messages on all the servers.
    Twice the space consumed by the same message. Multiply that by
    thousands of servers, or apply it to servers with limited storage and
    you may grasp the rationale behind this common sense advice.

    How you usually respond or what "annoys you" is immaterial if it's
    based on ignorance. Accepted Usenet behaviors have been around and
    commonly understood longer than you apparently have.
    Tom Thomas, May 6, 2005
  14. The most important rationale is that you can read all responses at once.
    I don't mind spending time helping people out, but I do mind wasting my
    time writing a response, only to find out later that someone else
    already gave the same answer in another newsgroup.
    Johan W. Elzenga, May 6, 2005
  15. Fine if that's the way you're going to be about it, I'm going to back the
    survivor NG where they complain about crossposting with the amazing race NG
    (even though there are former survivors on TAR).

    By the way, in case you're wondering, i am rooting for Boston Rob to win it

    Tom, on the point of X-posting to two revelant NGs - I agree hardily on this
    one. Not everyone reads both of the PS NGs, and often the solution to a
    problem will appear in only one. Most folk look to these groups for solutions,
    and they will be best served by an X-post, rather than independent articles in

    Me thinks you may have read too much into Tom's suggestion - but maybe not. I
    often hear the "do not X-post, ever!" crowd, but happen to disagree with them
    in this context. If my server only carries one of these NG (PS in this case),
    or I only monitor one, I might well miss the answer to a good question. I vote
    for Tom's suggestion here and advocate X-posting where there is a real
    purpose. Not all subscribers will know about it, or even be able to weigh the
    benefits, unless someone points it out to them.

    And, as has happened too many times in these two NGs, the OP will often
    question why no one responded to the post in one of the groups, because he/she
    has not bothered to check the other NG. Having to pen, "why not check my reply
    to your question in the OTHER NG?" gets a bit tedious.

    The example of on-topic, PS questions and two similar, but not identical NGs
    is a good case for X-posting.

    Especially since your answer to the OP was well thought out, and probably
    saved him a lot of tedious work, I'd urge you to not stray from the case at
    hand, two PS NGs, with slight differences in the subscriber base, and a
    question that fits perfectly into both. I will agree that there are probably
    more instances where X-posting is a BAD idea, but within the context discussed
    here, I'd vote for it - strongly.

    Though the problem was not mine, I did like your solution to it, and will
    remember it, should I be faced with a similar problem. Thanks for that

    Hunt, May 10, 2005
  20. You're missing the point. The point is not that the OP should not
    crosspost. I have no problem with that. The point is that he should
    indeed CROSSpost in that case (i.e. one message, with two newsgroups in
    the newsgroup header). He didn't do that. He just posted the same
    question in two groups as two different threads. That's annoying because
    that means you cannot see if somebody else already gave the answer in
    the other group.
