Re: I Hate My *ist D - Eclipse Photos
Reminds me of the time about twelve years ago when were traveling cross country in the wee hours of the morning. We had bought my son some glow-in-the-dark space stickers and the package was glowing on the dashboard. I turned to my wife and asked "Did you you know Uranus glows in the dark"? I think we stopped laughing about 20 miles later.

Well, it's actually Uranus.

Re: I Hate My *ist D - Eclipse Photos
Thanks Bob. I was expecting to be disappointed as we had cloudy weather after a week of clear skies. Luckily it started clearing at about the right time (just after the eclipse started). I just shot from my back porch, while wishing I was somewhere like Tekapo where the skies are about as clear as it gets and they're miles away from the light pollution of any city. Spaceweather.com had a really good photo taken from the South Pole, which even included a bit of aurora! - Dave On Aug 31, 2007, at 2:15 AM, Bob Sullivan wrote: > Nice one Dave!

It's definitely not a hot pixel as it appears in different locations in several of my photos (plus I saw it in the viewfinder and it does span several pixels). I'm wondering if it might be Venus as I remember that being very close to the moon not-so-long-ago. - Dave -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net

Hi Cory Thanks - I use Linux as well (dual boot with win XP) but compiling from source is something I've never quite come to grips with.

Probably doesn't help most people who use programs *based* on dcraw. The originial line of code read perc = width * height * 0.01; /* 99th percentile white point */ ... which I changed to perc = width * height * 0.001; /* 99.9th percentile white point */ or perc = width * height * 0.0001; /* 99.99th percentile white point */ I could have done it by manipulating the blackpoint and brightness settings instead, but I would have had to do that by hand.

There are two possible reasons that I can think of for what I see here... 1: Irfanview is based on dcraw for its RAW conversion. I've had issues with dcraw in doing starry-night conversions because of the way it decides on the white point. By default, I think it chooses the white point at the luminosity of the 99th percentile of the photo. Thus, by default, 1% of the pixels are blown out. I've changed that setting on my version of it a few times to make it 99.9th or 99.99th percentile for star photos. Works great. 2: The problem with star photos and the DSLRs is that the histogram cannot be set to logrithmic. When over 99% of the pixels are *SUPPOSED* to be black, you cannot tell if the 1% that are white are anywhere near exposed properly because the don't even show up on the histogram. It looks like you might have a combination of the two. Try the RAW conversion again, but make sure it doesn't add a bunch of brightness to it. -Cory -- * * Cory Papenfuss, Ph.D., PPSEL-IA * * Electrical Engineering* * Virginia Polytechnic Institute and State University * * -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net

That's interesting. I've had a similar experience with the interpretation of Raw files in Studioline Photo Classic, a program that I use for cataloging images. It also uses dcraw. The raw conversion of photos I took some months ago of Comet McNaught are all blown out badly in the Studioline conversions. I don't quite understand the setting changes you made to Irfanview. Can you elaborate?

We missed most of the beginning of the eclipse but it became clearer as the night went on. I took some photos with the K10D using the FA*400 both with and without a 2x TC. Focussing accurately was almost impossible. I haven't had time to even download the files yet.

Re: I Hate My *ist D - Eclipse Photos
I can't see your Picasa shots at work, but I just tried to open the*istDS .pefs in Pentax Photo Lab and could not. I downloaded the version of Photo Lab released with the *istDS and it opens and converts them in a much better manner, albeit with apparent loss of deep shadows. For the *ist DS at least, there must be something wrong with the irfanview algorithms. I'll give the new Photo Lab a shot on the noisy *ist D images as well. Thanks Peter!

Re: I Hate My *ist D - Eclipse Photos
I did the same thing with my ist-DL, and got the same crappy stuff. Talk about being p1ssed off! But I converted them to jpeg's using Pentax's photo lab, and to my surprise got sopmething reasonably acceptable. I had a Sigma 100-300 f/4.5-6.7 on the front, too - not renowned for its sharpness. Here's a before: http://picasaweb.google.com/petergly/OnePhoto/photo#5103871449239871586 And here's the same shot after I converted with Pentax's photo lab: http://picasaweb.google.com/petergly/OnePhoto/photo#5103871569498955890 I lost some shadow detail, but I'm happy with that compared to the original. Here's what I ended up with: http://picasaweb.google.com/petergly/2007LunarEclipse Given that this was my first ever attempt at this sort of photography, the cheap lens I had on the front, and the crappy Sydney air, I'm quite happy with these.

Re: I Hate My *ist D - Eclipse Photos
Thanks. Maybe I'll call them and see what it will cost. While I can believe my 3 year old *ist D has a problem I can't believe the crap that came out of the *ist DS. http://photo.net/photodb/presentation.tcl?presentation_id=355761 The first is ISO 800 f/1.8 for 6 seconds. The second is a straight up Milky Way shot, ISO 800, f/1.8, 20 seconds. I'm wondering if this might not be an irfanview conversion problem with these (PC with Photoshop crashed).

Re: I Hate My *ist D - Eclipse Photos
I used my old Canon D60 and a 100-400 EF zoom lens. I set the ISO at first to 800 and then to 1000. Exposures were still about 2 sec. long (I could see the stars beginning to "trail".) Of the 10 images I took, I liked just one. I might have gotten a better image had I waited until the moon began moving out of the Earth's shadow giving me more light. Anyway, seeing the eclipse was an occasion. Lunar eclipses are more common than the more spectacular solar eclipses. I read that another lunar eclipse will occur in Feb. 2008.
