  1. Following on from a current thread on the Wetpixel forum, @Alex_Mustard and @adamhanlon discuss their personal preferences with regard to using flip adaptors for ancillary wet lenses. Although popular and convenient, these brackets do have some drawbacks.
  2. The curvature of the dome itself can cause CA-and the way the lens combination interacts with the dome can also cause it. This is independent of the DOF issues caused by aperture. You can check the lens for CA on land, but not the dome, or the dome/lens combination. The port only produces a virtual image underwater.
  3. @Alex_Mustard is celebrating the writing of 100 "Be the Champ" columns in Diver magazine. The column is focused on underwater photography, and to celebrate its 100th edition, he approached a wide variety of underwater photographers for"one-line" advice. @adamhanlon and Alex discuss some of the communal wisdom shared and how fortunate we are to be a part of a supportive community.
  4. Hi Jay, The short answer is that we have not tried it yet...I would consult with your local dealer for pricing information. Adam
  5. While you can check a lens's performance on land, you can't check a dome's... The issue may be the interaction of the lens and dome rather than the individual components. As I mentioned, I think the CA is probably due to the size of the port.
  6. My experience with TCs on high resolution full frame has not been positive. I even bought the latest Kenko HD version, but I still found that the images were soft. I liked the results on cropped sensor cameras, but the D850 really showed their flaws. Similarly, I would not chose to use a 5" dome with a full frame camera, even with a fisheye. I think the CA that @Interceptor121 notes is probably due to dome size, rather than lens combination. My minimum size is 7" with full frame. Aperture plays a role here too. If you can always shoot with a small aperture (f/15 or so) you can get away with some things that you can't at f/11!
  7. The shark conservation charity, Bite Back, has released its annual calendar, featuring lovely underwater imagery from a variety of talented underwater photographers. @Alex_Mustard and @adamhanlon discuss the 2021 calendar and how successful the charity has been at engaging people in the crucial front end of shark conservation.
  8. @Alex_Mustard and @adamhanlon get out their crystal balls and try to predict what the buzz would be at DEMA 2020, which has been canceled due to COVID-19. They discuss the hot new products that have already made their way to the marketplace and try to guess which ones everyone would have been talking about at the legendary Wetpixel/DPG Image Makers Party.
  9. @adamhanlon and @Alex_Mustard discuss some dos and do-nots about using housing lanyards and how they attach their housings to themselves when shooting underwater. Both of them tend not to use lanyards a great deal, and they see out their reasons for this in the episode.
  10. In his "Essential Guide to Composition," Jim Church divides underwater wide angle images into 5 broad categories. Whilst it was written in the late 1990s, the advice still holds true for composing images today. Alex and Adam chat about how studying Jim's book and thinking about how composition works can pay dividends for all underwater image-makers.
  11. The celebrated underwater photographer and an artistic inspiration for a whole generation, Ernie Brooks, sadly passed away last night. @Alex_Mustard and @adamhanlon share some thoughts about him and his images and celebrate the stunning body of work that he produced over a lifetime of photographing "The Silver Sea." The Wetpixel community's thoughts go out to his family and friends at what must be a terribly difficult time. The underwater imaging community has lost one of its shining stars Please feel free to share any thoughts abut Ernie and his beautiful imagery here too.
  12. Could the patterning be something to do with the way the camera debayers during processing? These ones in the image above are definitely color artifacts, which would prompt me to think this is a color issue rather than a phase detect one? Banding etc. can all be caused in the algorithm too
  13. @Alex_Mustard and @adamhanlon discuss the finalists of the Underwater category in the GDT European Underwater Photographer of the Year Contest 2020. This contest, open to photographers based in Europe or GDT members globally, tends to select images that are photographically and artistically creative. This makes them a great source of inspiration.
  14. I'm unclear how phase detect in an SLR with a seperate phase detect sensor (i.e. not on-sensor) would produce the result? The AF sensor data is separate from the imaging sensor...the only way it could happen would be if the processor is somehow combining the two sensors into the camera's output? Even in Live View, the Nikon SLRs use only contrast detect. Adam
  15. Wetpixel Editor @adamhanlon and regular contributor @Alex_Mustard have both been shooting the Nauticam EMWL lens. Sadly, the UK wide lockdown has currently curtailed their testing, but in this episode, they give their impressions about this innovative lens system, gathered from their experiences thus far.
