  1. All three are sold now! Sent from my iPhone using Tapatalk
  2. two sold. The one on the far left (no diffuser) is still available. Also, thanks for the offers, but no trades please.
  3. I am back from my trip. I used the S&S strobes and they worked great, but I am going to use video lights next year. Much to my surprise, they were way more power than I need. Unfortunately, the water was a bit cloudier than I remembered, so I had to stay within about 15' from the surface I was shooting. That was my original plan, and would have been fine, except that the topography of the bottom of the cave was so complex that staying consistently 15' above the floor meant that I was hitting walls, i.e., there are boulders that are 20-30' tall, so I had to stop and go up 20' and carry on. I tried this, but it wasn't working. SO, next year I am going to use video lights instead, held by two or three divers down around 15' above the floor to illuminate it, and I am going to be up around 30' from the floor taking the pictures. I will be zoomed in and probably have to crop the images, but that will solve my backscatter problem. I need to sell the strobes now, and hopefully get the lights donated or loaned to me next summer.
  4. I bought these three strobes used in the spring for a project in an underwater cave. It was my first time using strobes, and it turns out these are (a lot) more power than I need. All three are tested on several dives down to a max depth of about 60ft and worked great. All three exhibited some corrosion on the battery contacts when I received them, but I scrubbed them with alcohol and haven’t had a problem. Two of them have the oem 100 diffusers, and all three are configured with the oem ball mounts. If I have no takers these will be up on eBay (seller: antillothrix). $350 each, shipped conus, PayPal only. UPDATE: the two with the diffusers are SOLD. One remains, with no diffuser, $350 shipped CONUS.
  5. thanks very much for all the great comments. Marko - yes, you're right, for photogrammetry. That's an interesting point about graininess and ISO. I'll have to test that idea. Fruit - thanks very much. I won't be able to make a change for this trip, because I leave this week. But I may have a chance to swap the strobes for the next trip next summer. I REALLY hope these work out for my needs, but having another field season already on the calendar allows for some mistakes. About the video lights, BigBlue look good but the output declines quickly, much faster and less even than Light&Motion or other lights. For you, or anyone else here with an interest, some white plastic bag and a rubber band works well to smooth out those sharp edges if you don't have a proper diffuser. As for brightness, using the light&motion 3k lights i got fine results from about 1.5-2 meters, but that was with a canon 5Diii, which is more capable in low light than my lumix LX10. I'l report back and post some images when I return next month. thanks again.
  6. Tried it, didn’t fit. That’s fine though, because in the lowepro backpack it is super protected. I considered using your trick anyway to reduce the chance that I do something stupid while opening the bag, but since it doesn’t fit, I used one of the dividers to add a layer over the lens before closing it. That way I have to un-Velcro the flap to remove the lens, even after the bag is opened. In the pic below I am holding back another Velcro flap over the center strobe (the flap over the lens is removed here).
  7. About 11 inches wide, and it’s a snug fit. I added a third strobe and my gorilla pod tripod, but I still haven’t played with rearranging it much. I’m thinking I will designate a safe nook for the lens and lose the big boxy padded case for it - save 1lb and a lot of space.
  8. i just read the short article here, http://wetpixel.com/articles/eneloop-batteries-not-recommended-for-use-in-strobes and was very disappointed. I JUST received my new enloop batteries in the mail yesterday for use in my strobes. now i have to decide whether to use them. I get it, there are plenty who use them and it works great, so i should be fine. it would help me make up my mind if i knew 1) why enloops are thought to be the best for strobes, and 2) if all the alternatives that I could use have "potentially" the same problem.
  9. those are amazing. thanks for sharing.
  10. diffusers are great for video lights, though i am almost saddened to say that a white plastic bag and a rubber band often can produce the same softening effect (though maybe not the increase in angle). Re: OP's question. If the light doesn't connect, tilt inward. If you haven't used the Solas with their diffusers yet, you may not have a problem. L&M are awesome and serious about their lights (check out their test site, www.wetestlights.com). I used the 3000s and found the edge was hard, so I used the bag trick to soften it. Later I tried a 3800 with diffuser (just in the house), and the edge is wide and soft. I do not think a second set of lights is the answer, at least not on the same rig. I considered using a pair of 1200s with a pair of 3000s. I had them all so I set up the rig -they're small enough that it can be done, but I have a hard time imagining it working well without making weird uneven lighting. No reason not to try it though. I wouldn't get a second set of arms. I was going to use a triple-ball clamp to hold two sets to the end of one arm. Then tilt each light individually. worked like a charm in my living room, but decided i didn't;t need the 1200s, because they made little difference to the intensity or spread of light (again, in my house). As for the lights you are using, I used a pair of 3000s in a cave and got great images and video. I very much doubt that light spread is an issue with 3500 (aren't they 3800?) with diffusers. If you're competing with ambient light, or want to reach farther, you may need to go up in power, but I think we'd have to hear more about your application to guess at that. Their 9000 (9600? i forget) is an amazing light, but it's way way way bigger and double the price.
  11. i've been using on1 for about a week now. i'm a novice, but found it easier to get around than my trial version of lightroom, and the many many youtube video tutorials have been a gold mine for me. that said, on1 is a little buggy. there are times when i'm adjusting a slider and my image goes purple or something, and there is one image that almost always shows a weirdly inverted filter in the preview, though that goes away when i open the image. i am hoping that all these quirks get worked out as the 2018 version matures, and i guess i'm willing to cope with them in light of the LR CC going subscription-based and the very high price of capture one.
  12. you've probably already looked at the panasonic lx10 because backscatter and others are singing its praises (see also discussion here https://www.scubaboard.com/community/threads/lumix-lx10.551061/)- but just thought it deserved a line in this thread. I didn't have an open budget, and would have preferred a canon 5d mk iv if price was no object for lowlight, but obviously that is the antithesis of going light. For a sense of how compact my kit is, look at this pic I posted of my lx10 with housing, lens and strobes all fit into my new backpack, in this other thread: http://wetpixel.com/forums/index.php?showtopic=60589
  13. I just received my new Lowepro whistler 450. My initial impression is that it is heavy, but capable, comfy, and well-built! I really like it! That's a relief too because I had to stop myself from reading more reviews after ordering because I was having new doubts. I will tinker with the arrangements but here is a first take for scale. It feels heavy to lift, but very comfortable and less heavy on my back. I’m 6’ tall, and it looks medium to med/small for a day pack, certainly OK for carry on but don't think it's going to fit under the seat (I have to look that up). I would hesitate to use the back side pocket for anything not easily compressed for flying. 2 x sea and sea ys-d1 strobes Nauticam housing with pro kit (handles) for a panasonic (compact) Lumix LX10 Nauticam wise lens IN CASE Nauticam floatation ring for lens
  14. old post, i know, and old review. Can anyone offer any additional experiences and opinions about these diffusers? the review said they're light hungry, which is concerning, but the website also says they are using a new material now. Any comments are much appreciated.
  15. hoy crap that's exactly what i need. thanks for posting!!
  16. I just went through this process. I was looking for a backpack, and here are my notes: Backpack with these criteria carry-on friendly and carries 15" laptop carries compact camera + housing + wide angle lens + arms, 2 strobes and video light carries additional expedition gear on site, e.g., GPS, jacket, lunch, small toolset, fins (maybe booties), shoes/socks ok to lay down in the mud ok to be in a truck bed with a dozen tanks and big heavy gear bags My candidates F-stop ajna - ruled out: too expensive with camera module, no rainfly, reviews state not super comfy, insufficient division of compartments, laptop sleeve too small (would require laptop case), bad customer service stories. Mindshift backlight 36L - ruled out: skimpy laptop sleeve not sufficient to not require laptop case, top compartment too tiny, material not very tough/water resistant - generally like a jansport backpack for high school but with a camera compartment. LowePro whistler 450 - purchased: pros - tough (mud friendly) material, expandable wet pocket, large top compartment, super protection in camera box. cons - heavy, no water bottle pockets, no laptop pocket (will require I use laptop case - more weight). I'll post again once I have a better idea of how well I like the Whistler.
  17. Dome diffusers have come up a lot, but I can't find a broad coverage of the options, and I wonder if there are new opinions about how to best create a soft even light with these aging favorite strobes. I am looking for the best option for wide angle shots, something budget-friendly, i.e., worth paying for when I already have the standard flat diffusers from S&S. Any opinions from the more experiences would be much appreciated. I'm sure that I missed some, so please feel free to chime in with any others worth looking at. Thanks. There are the white domes, which sometimes look cheaply made, or thick enough that they may lose too much light: Glowdive - http://www.glowdive.com/lightdome/index.htm Onderwaterhuis - https://www.backscatter.com/Onderwaterhuis-Pro-Dome-Diffuser-Sea-and-Sea-YS-D1-YS-D2 10 bar, cheapest of the lot - https://www.opticaloceansales.com/10bar-dome-diffuser-for-ys-d1-ys-d2-strobes.html Mozaik - https://www.housingcamera.com/id4740-mozaik-moz-diffysd.html unbranded? - http://www.prodiveimaging.com/products/strobes/strobe-accessories-diffusers/418-light-dome-diffuser-for-ysminusd2 The local favorite, I gather, has a new more transparent version for wide angle: CM series ii - http://www.cmdiffusers.com/product/cmdome-diffuser-for-sea-sea-ya-1d The "air-sealed" dome is sexy, but doesn't diffuse as well(?), and positive buoyancy might be annoying? FIT - http://fitprouw.com/index.php?route=product/product&product_id=2284
  18. thanks. I may start another thread about diffusers, because I don't know if the aftermarket dome diffusers are worth the money. (edit: I DID start that thread, here: http://wetpixel.com/forums/index.php?showtopic=61675)
  19. update - I scored a pair of S&S YS-D1s for the project. Hopefully they pack the punch I need.
  20. that makes sense. OK, so from the previous post, you do still think that strobes are the better option, but that I should be mindful of my distance. right?
  21. thanks for those comments. I have a wet wide angle lens. in much of the space I will be shooting from 5', because there isn't enough room overhead to get any higher. 5' really don't feel very far at all, and unless i don't understand about these strobes, i have a hard time believing that they don't have a good punch and spread at 5 or even 10'. My primary light blows out a shot if the spot is in the frame even at 15' from the camera. I guess there will just have to be a trial day to see how well it does in different scenarios.
  22. I'm so confused by this - I was using video lights but everyone has told me that strobes will be brighter. For example: http://uwlightdude.com/strobe-vs-video-light-for-still-photography/ http://wetpixel.com/forums/index.php?showtopic=56895 https://www.scubaboard.com/community/threads/strobe-vs-continuous-light.379817/ I could go with video lights, and I know what I'm doing with them better, but plan on using strobes because they're supposed to have more punch. DISTANCE shouldn't matter, right? if the strobe emits more light, then it should cover more area given the same diffuser (and I know they'll be different, but assuming everything else is constant, brightness = coverage). If I'm wrong about any of this, PLEASE correct me. I'm trying to learn this through the internet and there is not east way to test anything for myself before I spend a lot of money. I have a pair of sea & sea ys-d1 strobes on the way (haven't tried them yet), but if I need to use video light instead I could still go that direction. Any thoughts are very much appreciated.
  23. i've made some progress in assessing these options.... basically i've decided they aren't the best options. So, I'm looking for some more powerful used strobes. if I can't score some, I might go back to video lights because I know what works and I have connections to get discounts. here's a good discussion: http://wetpixel.com/forums/index.php?showtopic=59961
