Default Stuck at #1 in the Queue...

http://www.railpictures.net/viewqueued.php?id=301004

What would keep this stuck? (It's been there for about a day or so) My guess is that they could reject it for overexposure, but even at 15 second exposures the lights illuminating the ballast were blown out. Can't fix that. However of all the railgrinder shots in the database, I really think this one should be part of it.

Thoughts?

TIA,

Darrell

Default Stuck?

Hi Darrell,

I had a pic "stuck" for two days once, I emailed and asked what had happened, reply was that the screener wanted a second opinon from the editor.

It was an unusual pic so I quite understood. The next day the pic was on the database.

Default Bit Blown

Darrell, just looked at your pic, seems a bit blown in the highlights.

Very interesting shot though, do you have another with good highlights?

alan -

I took about 20 photos of various settings. When I get back from campus today I'll post up a few of them. The best shots seemed to be at about 45 seconds, F4 to 4.8 at ISO 200.

I had a thought to take one of the darker images and combine it with one of the lighter ones in MatLab's Image Processing toolbox to get some details back in the highlights.

That's what I would do. Film and digital can't really handle the full range of exposures that the eye can see. Your basic exposure looked good, perhaps you have one where the rest is underexposed but the ballast lights are correctly exposed. It involves some masking, but you can combine the two images fairly easily, especially if you kept the same tripod postion throughout. As far as I am concerned, combining two exposures of the same scene to overcome the physical limitation of the medium is legitmate.

Yeah, all shots were kept on the tripod, so we'll see what happens. However, like I was sayin' even the 15 sec exposures were blowing out the ballast...

How might I go about combining two images in such a way to get the detail back in the ballast? All I have at my disposal is Matlab, MSPhotoEditor, IRfanview, and MSPaint.

Thanks!

Here's some of the other exposures I took of the same scene (others not posted included different white balance settings.)

15 seconds
20 seconds
30 seconds
47 seconds
61 seconds

And here's one sharpened, and auto-color applied to it...

Default Bracketed Exposure

Darrell,

Thanks for showing us your bracketed shot, this as I,ve said is a really interesting railway shot, I just hope you can recover the ballast.

Best of luck

Alan

I'd see if a lower time shot is any better, but unfortunately this type of shot will always be either underexposed or overexposed,

Gernerally I shoot night shots at 2 seconds and 32/10 F-stop, but the areas I shoot in are well lit already, it's hard to shoot something that is its own light source.

Great shot of the rail grinder!

One time a friend and i were doing some trackside camping and one of these came through in the dead middle of the night. Being awoken by a rail grinder crawling along the tracks making a racket and lighting up everything with all of its lights was really really scary actually. We were a little paranoid too because we knew that we were technically on railroad property. When this thing crawled by and lit up our tent like daylight we really freaked, we ended up packing up right then and riding our bikes into the nearest town and sitting on a bench by the tracks until morning! ahh the memories!
