  1. While anything is possible, it is highly unlikely that the vacuum would cause an issue with the buttons. At -5 inches of Hg (the recommended vacuum to pull) is only 2.5 PSI or the equivalent to about 5 feet in water. So it's as if you're diving the housing 5 feet deeper than your depth. Jim
  2. Sorry to bust your bubble but the G12 will not work in the FIX G11 housing. The front dial sticks out and prevents the camera from laying flat when installed in the housing. You can close the door to the housing, but I'm too nervous to actually submerge it due to the extra force required to close the door. Because of this the zoom doesn't function and neither does ISO or mode. The Canon OEM housing works fine as there is extra space in that area of the housing and the front dial is well clear of the front. It's almost as though they knew when they were making the housing for the G11...
  3. I would chalk it up to a mistake. Sometimes it happens. I'll let Andi know.
  4. You can still do white balance in video mode by taking a still shot in live view video mode. This is how I usually shoot, I don't switch back to stills to do a white balance shot. Sorry to hear of your troubles with the housing. Let me know if you this has been solved or if you need any assistance. Jim
  5. You can do it by the same method on other Canon DSLRs. You need to take a picture of whatever you are using for WB (slate, sand, hand, etc.) and then assign that picture to use for WB. Then set the WB to custom. Make sure that the image is properly exposed otherwise your colors could be off. I've done a WB with an overexposed image and it came out puke green underwater. Being that the Rebel uses multi-function controls on the back of the camera, I can't imagine any underwater housing not having access to WB. Best regards, Jim
  6. We do get many calls and emails everyday, sometimes asking complex questions (such as how to do underwater time lapse for scientific research), sometimes very simple ones ("My strobe doesn't work" "Did you turn the slave to on?"). The person asking the question usually doesn't think it's a lame ass question and I hope that any of our customers don't feel that way. If there's a problem we can solve, even if it is simple, to get a customer up and running on a trip, then it's a good question. At Backscatter we provide free lifetime tech support on all purchases. We do spend time with the customer and try to figure out the best system that will fit their needs. That being said we do deal with a few people who call us, discuss various setups and the best options for them and help them decide on what to get, only to send them a quote and then they take that quote and buy their gear somewhere else. After they purchase their equipment form another store, we get calls asking how to setup the gear, what is the best shooting technique, etc. Unfortunately we can't answer these questions for them as they did not purchase their gear from us. Some people understand, but sometimes this causes the person on the other end to get upset. We can't support other businesses who sell underwater imaging equipment that don't have the proper training and knowledge to adequately serve their own customers' needs. We put food on the table and a roof over our heads by selling underwater imaging equipment and our advice and expertise on using the gear. Thanks for everyone's great responses on this thread. It certainly makes us feel good about what we are trying to do as a company, and also as people who are trying to make a living in underwater imaging. Best regards, Jim
  7. From what I've seen from our customers' feedback, most people are buying the G11 and S90 rigs due to the size and features, including quite a few tech divers. They just don't want to go up to the size of an SLR. I've also seen quite a few DSLR users get one of these systems as a backup system. Unfortunately with the way airlines are treating us with limited luggage for some destinations, size trumps everything else. Best regards, Jim
  8. Hi Jeremiah, I just wanted to comment that the flip macro from Fisheye for the G11 is designed to be used with the lens fully zoomed in with the macro setting turned on. In this configuration there is no vignetting and you can get super tight shots. Best regards, Jim
  9. Hi Aengus, Thank you for your kind words regarding the service you received from our staff. In the past due to being burned on a number of international credit card fraud orders we instituted a policy of requiring first time customers to pay by a bank wire transfer. Since then we do accept international credit card orders from most countries. For countries that have high instances of fraud (i.e., Nigeria) we still require bank wire transfers. I hope this clears up any confusion regarding our international credit card policy. Best regards, Jim
  10. Hi Nicholas, Good job! Nice to see your design work is as good as your underwater photos!
  11. We've shot the HF20 underwater in the WP-V1 housing and it worked fine. I wouldn't consider it overly fragile, it's just not made from the thicker plastic as Ikelite which costs more to do. The Gates and Light & Motion housings are made form machined aluminum, which costs much more to produce and are produced in much smaller numbers. Also the other brands tend to have more controls, and each additional control adds to the cost. The housing has a 67mm threaded port which accepts the popular 67mm wide angle conversion lenses form companies such as Inon and Ikelite. You can also add a color correction filter. Stix is coming out with a tray system for this housing that will have 2 ball mounts for lights. I can suggest the Fisheye LED 1000 lights, as they are self contained and small relative to the amount of light they put out. The handles and tray system carry the weight of the housing and lights, so there's no extra stress on the housing due to using arms and lights. I'll try to get pictures up of everything as soon as we get the products in. Best regards, Jim
  12. Hi Bearaway, We converted the clips to Prores 422 in Final Cut. This made them easier to deal with. Editing in H264 is not really an option. I tried it and the bit rate drops for some reason when it is output. When I added titles, it dropped to 4 mbps. I can playback the H264 at full res on my almost 2 year old MacBook Pro 2.4 core duo with 2 gigs of ram. When I output the 422 pro res file at full res, 179 mbps, it still played fine on my computer. We'll have to see what editing in H264 will look like when it is included in Final Cut. This will help speed up the adoption of cameras like the 5D II in the future for journalists in mass media who don't have the time to convert to 422. The review was getting pretty long with all that we tested. Editing in Final Cut is a whole other article/review in of itself. Best regards, Jim
  13. Hey Paul, There are a few manual exposure changes in this clip. The entire clip was shot with manual exposure mode. The goal was to show this as raw as possible, and I wasn't as concerned about a few imperfections that I would normally edit out. On some shots I was using a tripod, and the macro shot was done with Sunray 2000 lights. The system handled very well in wide angle with the 15mm. A tripod with the 100mm is mandatory. For the workflow I converted to ProRes HQ then added the titles and exported as ProRes before sending off to Mary Lynn. I had to go this route rather than editing in H264 because the bit rate would drop down to 33 as I stitched clips together, and 9 when I added titles. I have found that the clip looks much better on my HDTV than on my computer screen. On another note, you guys here in the video forum don't usually see me too much as I am usually over in the DSLR forum, but now shooting with this camera, I do not see myself doing much stills in the near future... Best regards, Jim
  14. I just received a prototype Fisheye Fix G10 fisheye conversion lens. I shot it yesterday here at Dutch Springs during the DUI/Backscatter demo days. This lens looks really good and my guesstimate on the angle of coverage is about 160-170 degrees. Need to do a little scientific testing with a lens board to confirm. Here's a photo I took yesterday: http://wetpixel.com/forums/index.php?autoc...si&img=2464 For those of you familiar with Dutch Springs, this is the Silver Comet. I was only a few feet away from the wreck. This will be one of the widest lenses available for compact camera. The lens should be released from Japan by the end of the month. Best regards, Jim
  15. Hi Pakman, For any Inon viewfinder installations we do not modify the customer's housing. The stock eyepiece is removed, and the the Inon viewfinder is fitted with a adapter that we make and then mounted on to the housing. The housing can be returned to stock condition at any time by reinstalling the stock eyepiece. This can easily be done by the customer. When we make the adapters, we make sure the viewfinder is set at the correct distance from the camera's viewfinder to ensure the best possible optical quality. With the other finders you have mentioned, the adapter is made to go on the outside of the housing by clamping on to the stock eyepiece. The Inon viewfinder was not designed to have a layer of water and a housing eyepiece between the Inon finder and the camera's viewfinder, resulting in less the optimal optical quality. I hope this explains how we install the Inon finders. Best regards, Jim
