blosshapperter: question to a knowledged guy - I haven't yet tried and I fear my time budget is running low...When I tell the camera to substract a black picture it starts another picture same duration with closed shutter.With a duration this long - will it get better or worse?
First, I tried a one hour exposure outside in my light polluted neighborhood and didn't end up white at all. YMMV, depending on where you live. I attempted light painting but the paint was extremely dull, due to the exposure time, but I didn't end up with a blown out shot. Definitely some noise, though. Could've cleaned that up in post.
Secondly, which one are you talking about? Both the clock and the ocean shot are pretty crisp. I can only assume you're referring to the clock. He may have lit the shot and capped the lens for the remainder of the exposure. Not exactly what I was hoping for with this challenge, but it's still within the rules, I suppose.
blosshapperter: I guess this long duration is a killer in nowadays sensors - unless they are cooled with fluid nitrogen or even cooler...I tried to shoot fireworks and the remaining light of the city was sufficient to produce light(!) grey within 30s so I cancelled even trying 100 times as long.On the other side I decided to try something in the minutes range next summer when the nights aren't that cold any more.
Hmmmm.... never heard of that.
Could you rephrase your question? I don't understand.
The_Wicker_Man: The answer - relatively simple (as was the set-up - no tripod, camera just sitting on a couple of books facing the clock). Shot in near darkness, except for at 12 and 1 when the lights were switched on for a couple of seconds. The clock has no s hand.
Shot without long exp NR so to be honest thte result was pretty horrible. But B&W can cover a multitude of sins :)
I could re-try, but it's only a DPR Challenge and since this may be my one and only 1 hr exposure I ain't bothered. All good fun.
Ah, now that makes more sense.
Where did you hear that long exposure photography overheats sensors? LE Photography is pretty commonplace. If you're blowing out your images after 30 seconds, bring it down to minimum ISO and min aperture (higher F-stop number). a 60 minute exposure won't work in bright environments, though.
That's strange. You'd think there would be trails behind the minute and hour hands, with the second hand barely visible. Was the clock moving?
Pr0peller: JAYSUN: you are saying that DPR members complain when Exif is unavailable.
Taking my photo as an example I will argue that there's little useful in Exif to takes his/her own pics.
The Shutter speed is 3600 sec, a given. One may consider 100ASA a given as well for better resolution, and low available light.
One sets the aperture between f/16 to f/32, and start adjusting the LIGHTING until one gets a satisfactory reading on a lightmeter (1hour/f/16-32).The LIGHT- its direction, color, intensity - this is the big unknown and deciding factor that just looking at Exif teaches one zilch. One has to WORK on it.
BTW it does not matter if the camera is film or digital. One has to set the same ISO, Speed, Aperture values, although for film one has to account for its characteristics at long exposures.
Instead of looking at Exif, time is better spent looking and learning from paintings, drawings and photos by the masters. There's more in a pic than just technical data.
If you're not familiar with the backlash from the community, have a look through this forum...
Pr0peller: JAYSUN: I PROTEST!
You have DQd that truly beautiful picture of the Orion in the sky with the ruins.
WHY? Because it is stacked? I wish to remind you that Photography is about capturing light, not about how many times the shutter is being actuated. The time was close to the required one, and you should even appreciate the technical feat of the author.
I beseech you to reconsider and reinstate that pic.
I would vote 5 stars for it, although I have my own pic displayed here as well..
As I stated, the rules are perfectly clear. A single, one-hour exposure. I haven't hosted a challenge in a while. I started this one because I was curious to see what different shots people could come with when they're required to leave the shutter open for an hour. In this case, stacking doesn't qualify. If I allowed stacking, it negates the entire reason for the challenge.
I assume you're not a challenge host. I've been doing this for a little while now. When you create a challenge with specific technical requirement, such as the one in this challenge, you will always (without exception) run into much of the following:
1) Entrants using photos that obviously don't fall within the guidelines. Most of the time, it's obvious these people knew they were violating the rules because they never protest when you disqualify them. 2) All of the other entrants will contact me to notify me, repeatedly, of the photos that don't qualify or have no exif
You can't please everybody, my friend. I've learned that I'm much better off strictly enforcing the rules than letting questionable entries through. The rules are pretty clear.
And it absolutely matters if the camera is digital. You're entering photo challenges on a site called Digital Photography Review.
Jaysun: Only 3 photos have been submitted so far. Already had to DQ two of them for no exif data. I'm on the fence about the only remaining image, as I know it was shot with a film camera. I really hate having to DQ people, but you know how it goes. On a technical challenge, no exif = DQ. Have to keep it fair or the complaints start filling up my inbox.
Fair enough. I assumed from your earlier posts that you used a film camera, meaning the exif data would've had to have been added afterwards.
Nazeer Halawani: is light painting allowed?
Absolutely. As long as you do a 60 minute exposure, any photo is allowed.

No stacking. Sorry.
Tell me this... how does a film photo contain exif data? It would have to have been entered by the user, using an exif assigning program of some sort, correct?
You're absolutely right. I didn't read the rules well enough. Bring on the DQ.
Thank you. It's one of my better ones, for sure.
Wow... 26 entrants disqualified for entering shots taken before the challenge announcement or having no EXIF data (the vast majority for the former).
I haven't been a challenge host for long, but this is a new record for me. What is it with people? Sheesh.
I agree about having more rules, but most of the other folks on here do not seem to share our opinion. As a challenge host myself, I've started trying to make my challenges as vague and open as possible, so as to avoid constant complaining a griping about restrictions.
If you're saying that ConanFuji's rules are making for higher quality photos, though, I'd have to disagree. Theoretically, only allowing previous winners to enter would result in better shots but, in practice, it doesn't seem to be working out that way. Just because someone took first in a light painting challenge doesn't mean they're qualified to shoot B&W portraits. I'm a shining example of that. I placed in the back of the pack on his last challenge. I'm considering entering this one just to try and redeem myself but, as you see, it's a ghost town.
brentbrent: You know, there are many challenge hosts who get negative comments of one sort or the other about the challenge. Most of them don't just delete them.
To provide a differing point of view, I'd just like to mention that I like the challenge rules. There are many, many people that have won previous DPR challenges so, while the pool might be a little smaller to draw from, it should still be large enough to get enough entrants. This challenge is a bad example. I entered your last one, though, and couldn't get into this one because I lent my gear out (A shame, too. My girl was excited about getting a good B&W of us). Next time, perhaps.
RuthC: I'm no off-roader, but it seems to me that having a Capture Date for this topic limits entrants considerably in their choice of pictures. IMO, this will encourage the Date-Cheaters, rather than getting them outside on their bikes.
You're good, Alexx. I got your revised version w/ EXIF data.
