Canon 7D video ISO sweet spots Photo

Canon 7D video ISO sweet spots

This is very interesting. One of our readers pointed out a video demonstration that shows the noise characteristics of video shot by the Canon EOS 7D digital SLR. It shows that video can be quite noisy unless the camera is set an ISO that is a multiple of 160 (what many have said is the “native” ISO of Canon CMOS sensors).

I highly recommend clicking through and watching the video, as it is quite illuminating.

Canon 7D underwater housings: Aquatica vs Nauticam Photo

Canon 7D underwater housings: Aquatica vs Nauticam

Ross Gudgeon (AKA “Gudge”) has written up an informative comparison review of Aquatica and Nauticam underwater housings for the Canon 7D.

The timing for this article is good; both housings are priced similarly (Aquatica: $2800, Nauticam: $3200) at $2,800 (street price), and we’ve gotten a lot of mail from people who have been paralyzed with indecision as they waffle over which one to get. If you have opinions about either housing, please click through and share them with us!

Nauticam underwater housing renderings for Canon Rebel T2i / 550D Photo

Nauticam underwater housing renderings for Canon Rebel T2i / 550D

Nauticam has release a few renderings of their upcoming underwater housing for the Canon Rebel T2i / 550D digital SLR.

Notable changes from their prior housings include an ISO button / piano key located near the shutter release, and a standardized play lever by the left handle (where it is also located in their Nikon housings). The Rebel series SLRs do not have separate dials for aperture and shutter speed, but the addition of ergonomic access to the ISO button means that in future housings, all three exposure controls will be accessible without removing one’s hands from the handles.

Screen play for yet untitled movie, tentitively titled, “A Lawyer”

When entering photo competitions (or when uploading images to websites), you should always find and read the fine print to see what rights you have just granted. In general, responsible photo contests should only have rights to use your images in conjunction with the contest itself (e.g. announcement of winners in publications and online, for promotion of future contests, etc.). But many contests, especially those run by larger organizations, state that they can use any entry however they want, in perpetuity. In most cases, the language is boilerplate and may not be something an organization intends to take advantage of; Regardless, you should only enter contests and upload images if you are comfortable with the language.

Last call for Scuba Diving magazine’s 2010 photo contest

Scuba Diving Magazine’s has issued a last call for their 2010 photo contest, which ends this coming April 20. Prizes have been donated from various dive operators and equipment manufacturers.

The contest costs $10 to enter (per image), and is only for U.S. residents who don’t live in Arizona, New Jersey or Vermont. Note that there is some controversy around the rights of imagery in this contest; as always, you should read the fine print carefully and only enter if you feel comfortable doing so. There is a long discussion about such issues in our forum, which includes an illuminating screenplay about lawyers written by Drew Wohl, one of our moderators.
