  1. Guide to panoramas

    Well, I also noticed ptgui does that, at large RAW setting ( 4x18mp or 72mp) i get say 10100*5050px pano out of a 12 image 360*180 sequence of shots, If you turn it to polar, suddenly the optimal resolution jumps to an insanely hig number ( like 18kx18k px, which corresponds to 324mp ), way higher then your initial actual pixel count of 72mp. Alarmbells going off inside, pixels cannot quantum leap, must be stretching sth somewhere. It has something to do with the way ptgui renders the images pixels, - on a regular equirectangular image, optimal max resolution is when the middle horizon ( so the 2 horizontal rows of pixels exactly inthe middle if heigth is an even n° of pixels, which it usually is, and preferably horizontal width is divisible by 4) has a has a 1:1 pixel ratio with the original images. For equirectangulars i tend to stick to 10100x5050 px, which gives me 4x336mb 16bit TIFF files (3 brackets and 1 tonemapped 51mp each ) panorama that could be printed up to 67,3x33,7" as a 150dpi normal photo print, or as a 33,7" x 16,8" 300dpi hi-res print - when you change to a little planet projection, suddenly this number jumps to an almost ridiculous size, which I suppose is the program taking a 1:1 px ratio in the center, and stretching pixels the further from said center. I have all my little planets created as 6k*6k px files, which makes for 4 x 36,0mp files each 220mb in size. These can be printed 20" square at 300dpi, or 40" square at 150 regular photo print resolution, even in that case, at 300°x300°, there is already clearly visible pixel stretching at the edges though. Of course, there is a vast world of difference in our workflow... Fisheye vs standard lenses is a totally different world, my max resolution would be 18mp x4 = 72mp, The 21 superfluous mp are mostly overlapping areas with a 100x 10 mp photos ( No HDR! if HDR, divide by number of brackets but le 1000D doesn't have HDR i seem to remember? or did you get Magic Lantern?) You could theoretically get to 1 Gigapixel, anything above that are most likely pixels getting stretched out. do this minus your overlap, which ought to be around 25 to 30% and you end up with a theoretical max res of 700-750 mp? Just for fun's sake: Such a 722mp (38kx19k px) monster (somewhere round 5 gb as a tiff? ) at 150 dpi, would give you a 253,3" x 126,7" print
  2. Guide to panoramas

    Fekneejit, i've been horsing around with panoramic photography for couple years as well What's your preferred lens for this? I usually use my trusty Sigma 8mm fisheye which gets around in HDR in 12 ( 4x3 shots) Which gets me nice 51mp (10100x5050px) panorama's. I can only imagine what happens if you build from 100 images, that gets you what, a 0.5 (32kx16k px?) gigapixel pano? I've been wanting to try it with a 50mm 1.8 ( would be an 85mm lens on my machine, but I have yet to find a suitable location that is interesting enough for the trouble I'll post some of my stuff in this thread later! Meanwhile check the website in my signature for some of my virtual tours
  3. UK Grimsby Ice Factory - Feb 2015

    Top notch report!
  4. Paid a visit to a historic Belgian location, aptly codenamed the black gold distict. If you're keen on decay, this is the place for you. Couple more ounces of decay and it would be a pile of rubble. Everything is essentially covered in an inch of coal dust, and most base pictures were rather bland. Instead of taking the black and white route as most of my co-explorers have resorted to, i decided to edit the hell out of it to bring out some of the color. This place is in extreme decay, in some places entire concrete ceiling slabs have come down, tearing everything in their way with them. Also the floors that do remain are of varying quality. Watching your step and what you are standing under is a prerequisite for trotting around here. We were good for 4hours, making our way from the lower intestines of this humongous facility in search of that epic hall with a 6-track train station, but once there after an hour we were suddenly surprised by three friendly policemen and the facility's caretaker. As we clearly stood out as photographers and not copperthieves, they let us off with a friendly warning saying this building is really not secure. A statement to which i could not agree more. ( on a sidenote, they said we were spotted by people outside, which is a great BS story, I am pretty sure they have installed some cctv camera's in the main hall as they also figured out it is the main photographer's magnet and to prevent people from climbing the massive towers we were about to climb ) So, funny enough, after a 4 hour climb up we suddenly found ourselves standing outside in less than 3 minutes. A great day!
  5. The Analog Urbex [facebook group]

    DecayMasters, you definitely should! Ever since i found this old pentax i've been lugging it to abandoned places just in case I see that special sth that would make for a great analog pic. Shooting film is a very interesting experience, definitely takes more awareness and premeditation then just filling cards on digital. The group is a little light on content for the moment, but i'm getting some rolls developed more to come real soon!
  6. Belgium lost plane, january 2015

    Wow, this one is usually known as the Hawker, I took one of my favourite pics ever of that beauty. Problem is the site is now reconverted to a campus for training emergency services, police and even special forces. We requested access politely once, but got denied because of "terrorism threats" Few day's later, I just stumbled in at dusk... but didn't get into the plane. Nice one!
  7. In this age of hypercoated glass, super-ultrawides and space age image editing, the merits and intrinsical beauty of oldskool analog photography is often easily overlooked. Hence my new little facebook group: The Analog Urbex. https://www.facebook.com/groups/AnalogUrbex/ 100% Analog pictures of explorations and urbex related adventures. With 3 exceptions: - You can of course digitally scan your image, or photograph it digitally, as long as the base material is film. When in serious doubt, users might be asked for a discernable pic of their negative. Editing is allowed - Digital pictures of the gear you took your analog pictures with are acceptable - Relevant comparisons stemming from deep philosophical discussions on the analog vs.digital subject, we can't say no to that can we!? The group is off to quite a slow start, due to the fact that I can't actually seem to find more than a handful of people that still do the analog thing. I just turned down the analog path myself with a Pentax ME that was obviously destined for exploration (In the sense that I found this beauty 'abandoned' at a recycling yard, in full working order, with a 135 Takumar lens as a bonus. The stuff people throw away these days!) If you can't become a member on the group page itself (it's a closed group) drop me a message! Come show off your analog works of art over at the The Analog Urbex! And don't forget to join the cover photo contest! (To ye mods, If you wish I'll link a group post back to oblivionstate.com as soon as we get some activity going!)
  8. What camera do you use?

    Canon eos 60D here, mostly with Sigma 8mm fisheye ( maybe my most prized possession) Samyang 8mm fisheye Canon's new 10-18mm Tamron 17-55mm And the old 50mm plastic fantastic ( a dazzling 85mm gem on my cropped cam) On top of that a small collection of M42 lenses with eos adapter, A Pentax ME Analog (K-mount) camera with 50mm and 135mm lens, In the near future, add an analog Nikon F2 with 28mm & 50mm and some nikkor medium zoom lens to that, I first have to get some batteries for it, though And I sometimes borrow a friend's Nikon 3100 with his kit 18-55 and 55-200 lenses to combine with yet another friend's Sigma 8-16mm for these times when an extra body comes in handy...
  9. Purple blobs with long exposure?

    100% certain it is the variable ND filter, that's what you get when you turn it exactly to max I used to use 2 linear polarisers as a DIY ND filter, and that's what it does. thing is the sweet spot should be rather narrow, turn it half an inch to either side and blob should be gone!
  10. Hello I'm Jef AKA BenderFX from Belgium. I've been exploring for a good few years now, mainly Belgium, some netherlands and France too. I'm mostly into Heavy Industry/military/energy and other things that contain big machines but will give anything a go You can visit some of my explorations at my website http://www.rondomrond.be
