The Science of Shark Attraction?

04 December 2017 - 02:22 PM

Dear community,

 

As underwater image makers, we often capture imagery of sharks and other apex marine predators.

 

There is a lot of talk about whether they are specifically attracted to colors or areas of contrast.

 

My understanding is that it is less a color preference and more an issue of some species being attracted to areas of contrast, particularly when they are being moved (e.g. light colored fins or the contrast between white hands and dark wetsuits.)

 

Would Wetpixel members be willing to share their thoughts and experiences of this? 

 

Similarly, I can't find any academic papers that discuss this. Does anyone know if any exist and if so in which journal(s)?

 

Thank you

Octopus abuse on National Geographic

21 November 2017 - 03:38 AM

Dear Wetpixel community,

 

National Geographic has decided to feature Michael B. Hardie's image of a day octopus (Octopus cyanea) apparently “hitching a ride” on a Hawaiian green turtle (Chelonia mydas) on its Facebook page.

This image was captured by the photographer by removing the animal from the reef, taking it up into midwater in order to take pictures of it in the water column. It was then released and in its stressed state, blundered into the turtle, which resulted in this image.

 

Here is the photographer's own account of how the image was captured:

Thus this image does not in any way depict natural behaviour, and shows the results of actual abuse of the animal.

 

If you look at the bulk of the interactions with the post on the NG page, people assume that it is naturally occurring . Surely NG should be responsible enough to ensure that the images they use to promote their Natural Photography contests should actually be natural?

 

Please can I ask that the Wetpixel community take the time to add a post or comment on NG's page saying that this is unacceptable please? For those that have contacts with NG, perhaps send an email?

 

Many thanks

Full Circle Fisheye: Yes or No?

13 October 2017 - 11:00 AM

I have been watching an interesting poll on Facebook posted by Allison Vitsky Sallmon (@vetdiver) about full circle fisheye images.

 

https://www.facebook...&type=3

 

Typically this are images created with lenses with a focal length of 8mm on full frame sensor cameras and 4.5mm or so on cropped. Of course, it also also achievable using Photoshop in post.

 

In the interests of the poll being available for some time, I have added one here too.

 

It is not mandatory, but if you feel the urge, please feel free to comment on what you like/dislike about this type of image too...
