  1. I was recently diving in Belize and shooting video with my new D7000. Since I was shooting video, I was using available light and wanted to measure it. So I took a gray card down with me. I was rather surprised when I used the dropper in Aperture to measure the white balance. According to Aperture it's 50,000K. No, I didn't accidentally slip an extra "0" in there. Honestly, at 50,000K the gray card does look correct. But, I don't think any camera let's us crank the color temp up that high. At what white balance do other's shoot video? Thanks, Kevin
  2. Also, to those saying that other housings are better because they have more controls; I only have experience with Seacam housings. I own three; F100, D1X and D7000. I have several lens ports and an S45 viewfinder. They have traveled the world with me from Fiji to Galapagos and have always traveled well. I once had the flood alarm go off on my D1X during a dive in Cayman. I slowly made an ascent including a safety stop. The camera is replaceable, I am not. Once back on the boat, I opened the housing and found a hair on the o-ring. The felt inside the housing had absorbed all of the water and the camera was completely dry. I let the housing dry out and went back to using it that afternoon. I doubt many other housings would have faired as well. Kevin
  3. If you put the camera in Aperture or Shutter mode, you can use the sub-command dial to change ISO. I discovered this during my current trip to Belize with my Seacam and D7000. So far I like the housing. It' so much stronger than an Ikelite. I also discovered that it's better with the Pro G viewfinder than with my 45 degree viewfinder.
  4. I am pretty sure you are correct. Final Cut doesn't edit AVCHD directly. But, a powermac can't even import the video to a new codec. That requires an Intel Mac.
  5. Cayman is great diving. I miss it terribly. I lived there during 2004 and got to dive every weekend and many weekdays. Oddly, I was one of the few Americans living there. Most are from Canada or elsewhere. During the 2004 hockey championships I was dubbed an honorary Canadian by my friends at Legends. Great shots. I'm curious if you ever got to work with Cathy herself? Before moving there, I called her just to ask about being an American living there. I was less than impressed with her friendliness. I never dove with her. I did my PADI instructor course while there with Cayman Diving School. Actually, I'm planning a dive trip to Cabo with Renee (owner of CDS) early May. Kevin
  6. Based on another post here, I broke out my seacam F100 housing and my D300. Looking at the two cameras the controls are all pretty much in the right place. In trying to mount the D300 in the housing I find that I need to modify the mounting plate a bit but it sure looks like it can be done. I realize I wouldn't have access to the screen or play controls but I really don't use them on my D1x when diving anyway. It sure would be nice to save some of the investment in the housing and use it on a newer camera. I'm also going to check my D1x housing and see how close it is. I would have to build it up a bit or maybe get the grip for the D300 to match the height of the D1x. Has anyone else tried this? Any success? Kevin
  7. Just adding my vote for Fuji Velvia! I have tried lots of film over the years and will only shoot on Velvia now. When I'm shooting film.
  8. Even though I have a DSLR and housing, I still take my F100 down at times. I love that camera. I shoot Fuji Velvia slide film and get great colors! I find that print film just doesn't capture the colors under the surface. It's easy to get prints from slides if you want to hang them. When I lived in Atlanta I discovered H&S Photo and used the exclusively for developing and printing. They use dip tanks and I never had an issue with them. The prints they have made for me over the years are brilliant and very well done. They always followed my cropping instructions. The F100 is a great camera for dive photography. You'll want to get a strobe or two. I have the SB-105's and love them. If you are going to do wide angle stuff, get some long arms for the strobes. Now that I'm back living in Va, I use them via the mail. Kevin
  9. I know this thread is old as the hills. But, I just found wetpixel. Actually the software does quite a bit in determining the coloring of raw files. Based on the discussion it would appear that everyone has a good idea about the Bayer array in front of your camera's sensor. If not there is a good description of it here http://www.cambridgeincolour.com/tutorials...era-sensors.htm Each individual pixel determine it's level of light however, the actual color of the pixel is not determined until the software evaluates the pixels around it. Only then can the actual color of that pixel be determined. So in the strictest of terms, the sensor has no color gamut. It is the entire system; bayer filter, sensor and software interpreting the sensor data that determine the gamut. On most, if not all, digital cameras the WB data is included with the raw file simply as reference. No WB correction is applied to the raw sensor data. When the raw file is viewed with software, the software has a profile for that camera and that raw file. Through interrupting this, the colors of the pixels are determined and the raw file can be manipulated for color. I was recently going through some old photos from a dive trip to Tahiti. I had some raw images that were practically black. After some heavy lifting I was able to pull a decent looking photo of a leaf fish from the dead. The photo, not the fish. The fist was very alive.
  10. One caveat to the Mac being compatible is that if your video camera uses AVCHD, only Intel Macs support importing that video. Once imported you can edit on a G5 or G4 Mac. This really bugs me since I do most of my video work on my Powermac G5. But my laptop can import and then I just move the video over. Kevin
