[edit] Urban Explorer, Hobart, Tasmania

Seems to meet the technical standard, high resolution, free license, accurate, adds value to an article (urban exploration) and clearly illustrates the subject. There is a little color fringing (visible at 100%) on the top left hand side, I am wondering if the image should be resized such to eliminate this (but maintain resolution requirements), or if the extra detail in the rest of the frame would be more important. There many also be some image manipulation possible to reduce the distortion. Any other input would be good too

• I really like this. In my mind it would have a good chance at FPC, but you can't predict what will appeal to voters (some may for example say that this is an easily reproducible shot and complain about minor technical details like the slightly blown highlights at the top or the shadows at top right and off to the left). I can't comment on all the technical details because the 5MB filesize discourages me from looking at it fullsize, but at image page size I can't spot many other obvious flaws.

OK, what do I like about it? I think it's a very good capture for this topic showing the explorer in slightly 'scary' garb suitable to his cause about to disappear into the tunnel (now some voters may complain that he doesn't look animated enough). He is framed by the copious yet interesting graffiti and the running water at his feet, even including some detritus on the tunnel floor. Re the shadows and lighting I mentioned above, as I said some voters may complain, but I find the lighting very atmospheric for the photo, with the daylight pushing in from the top and the picture disappearing off into inky blackness in other places, showing what the explorer is heading into. OK, so to me, very good work and worth a try at FPC.

Some suggested improvements first though. I think it could do with more detail in the description on the image page (e.g., where 'under' Hobart is this...). I think it could it go to a more prominent place in its article, as it is superior to the other pictures. It could also probably be a slightly bigger size at thumbnail in the article as we rather lose the explorer at that size. I wonder if it may also be useful in any other articles, for example is there any relation to this explorer and the Cave Clan?

Good contribution and good luck. --jjron (talk) 14:26, 29 May 2008 (UTC)

I could only provide approximate location underground; It is hard to give the location when you have been walking without known landmarks in sight for a kilometer or two. I'll have a look at some satellite photos later and see if i can pin point the location. There is no direct relationship with this explorer and the Cave Clan, however there is plenty of cave clan tagging where this picture was taken. Animated explorer was not really too practical for this shot, as the longer exposure was required to get a good balance of natural light. I could have pushed the ISO considerably but this would have increased the noise etc. If you look at the full print the explorer is holding a flashlight. The highlights at the top left are not blown due to over exposure (take a look at a histogram) I think its actually some lens distortion (common on my 17-85 IS USM). Either way, I have done some editing to remove the Chromatic aberration on the top left hand side, now it looks good at 100%. The edited picture is attached on the right, let me know if you think its an improvement. Noodle snacks (talk) 04:49, 30 May 2008 (UTC)

OK, with the opening to the street above I thought it may have been possible to pinpoint where this was, having said which I have been to Hobart and realise that there are lots of these openings to the rivulet from the streets. Yeah, I figured it was probably a long shutter speed, I was just identifying the fairly casual explorer as something some may complain about. This camera could have handled ISO400 quite successfully (I have the same camera), having said which there appears to be some noise already, more than I would have expected. Looking at the fullsize, you're right, there are some weird things going on up at the top where the light is coming in, even in the edit. There are some blown areas at the top, I don't think it's anything to kill the nomination, but they are definitely there. With those problems I don't know how easy they would be to fix as they're a little unusual, but it does come up a lot better in downsized form; a 50% downsize really covers those problems, and still comes in well above requirements at 1944 x 1296px. Will leave it with you. --jjron (talk) 14:06, 30 May 2008 (UTC)

• Well I think this image is just captivating... if it weren't interesting enough it's got a mini-waterfall thrown in for good measure! The overexposure in the top left seems like the main issue. And from this angle the smaller side tunnel's circumference is clipped. I don't have a problem with the explorer's appearance... he looks weird, as any underground explorer should look. His flashlight is not easily discernible until viewed at the high resolution. I don't have enough experience here to say whether it's a viable FP, but hey, I like it. It looks cool in B&W, too.
