Jaysen dog-foods challenges

Challenge series hosted by Jaysen Marais. Challenges start on Saturdays.
This is where I (Jaysen) try out slightly more oddball challenge ideas and do my best to 'dog-food' the user-hosted challenges side of the site (dog-fooding is a software development expression roughly equivalent to "using the software one writes") .

Winner: Hellnar Church
Images whose primary subject is naturally framed by another subject. Port-holes, breaks in the foliage, windows, the eye of a needle. The framing must be clearly evident and absolutely no post-processing borders allowed. Good lucj

Winner: Final light in the spray.
Many countries in the northern hemisphere are experiencing 'daylight savings time', whereby clocks are brought forward to give us an extra hour's sunlight after our working days. I want you to get out there and make the most of this extra hour's daylight. I'm looking for shots taken late in the day (no night shots) since the challenge was announced.

Winner: Too many choices?
Sometimes, despite the best of intentions, man-made creations either don't do what they're supposed to or conflict with other objects and/or their environments in such ways that we can't help but shake our heads. I'm specifically looking for examples of counter-productive human creations here, no poking fun at the natural world itself. Bear in mind that some designs are elegant yet unintuitive,...

Winner: iPhone
We want to see you take on the newest (and most maligned) photo genre: the arm's-length self-portrait. A shot of you by you minus the trusty tripod is the aim here. Get the camera in hand and get creative with your lighting, setting and composition. Prove to the social-networking crowd once and for all that the arm's-length self-portrait need not be mediocre.

Winner: In the harbour
Put away those interchangeable lens bodies, dust off the compact (old or new) and focus on something, well, compact. Anything which economizes on space is acceptable: gadgets, animals, architecture etc. Remember, compact doesn't necessarily mean small, large items can be compact too!

Winner: Machu Picchu through a Fisheye Lens
How creative can you get with the wide angle lens? Show us what you can do with lens sporting an effective focal length of 35mm or less. Remember to tell us what lens you've used (no fibbing) and on what body. Compact and SLR entries are welcome, but make sure the lens used has an acceptable focal length (check our Camera Database if you're not sure). Oh, and no borders! Good luck.

Winner: Waiting for my Best Friend
Waiting for the bus, waiting for inspiration, waiting to be used or just waiting for something better to come along. Who (or what) is waiting, why and what for is up to you, but your photo has to convey a clear sense that your subject is in some way incomplete. Oh, and no borders!
