Assignment 26 - Sharpness

[Sheiky]

For this assignment John (neuroanatomist) has selected the following subject: Sharpness!


Assignment description by John:


"No, not that kind (even though I don't mind staring at ISO 12233
charts!). The subject of this assignment is, literally, things that are
sharp. Subjects must have an edge or point that is able to cut or
pierce something. A few small examples below, one each from animal
(broad-winged hawk), vegetable (rose bush in the garden), and mineral
(Wüsthof bread knife)."





The following photos have been selected as favorites, it's now up to you to vote for the best!

Ok, I'll Start this one off with


Splitting hair (the blade is a Japanese Katana crafted between 1480 and 1500 and will still shave the hair on my arm)

[Andy Stringer]

I thought I was going to have to double-check the AFMA for all my lenses when I saw the subject, but I like your interpretation of sharpness, Neuro.

Good start, Bob. How big is that blade? Looks like it's sharp enough to cut your arm off, not just your hairs.

I'll try my luck with this prickly pear cactus from South Plaza island in the Galpagos.

I didn't want to go with the route of a macro shot for this assignment so how about a jet cutting through the air?

I'll build on the jet example and throw and arrow being shot through the air in here...

[Dr Croubie]

damn, 2 images in and my knife and cactus ideas are already taken (I have some good sharp chef

[rlriii13]

Cut some cactus with one of your knives!

[Dr Croubie]

Yeah, I was thinking of that earlier today already. Certainly got enough to spare...

[Kayaker72]

Plenty of room for improvement.......so these are just for fun...my attempts from today:

Nice concept Brant....


I am starting to think John should have included a safety disclaimer for this assignment.

[bob williams]

How big is that blade? Looks like it's sharp enough to cut your arm off, not just your hairs.


Andy, Its total length is 39 inches, exposed blade length is 27.5 inches and yes it would probably cut anything off of a human that you wanted to cut off---it probably already has:)

[Dr Croubie]

Safety Disclaimer? What's that?

No, I'm not a junkie or a diabetic. The needle is from when I had to give my dog daily allergy shots ...he will vouch for me that it is very sharp! Yes, the DNA is mine ...it's amazing what a person will do for an assignment!

Denise, that doesn't look like any fun; however, I like your enthusiasm. :)


How about fangs? They are pretty sharp!

I'll try with another bird picture...Not the best, but I think the blood on the beak accentuates the sharpness....

This is my first submittal on any website. I just started pursuing photography and thought these assignments will get the creative juices flowing.

<p sizset="0" sizcache="15"]Hi, this assignment made me remember a kind of strange period of tableware photography I had a couple of years ago. I went through the archives but didn't find anything I liked, so I took a new shot at it yesterday.

Buck Knife


So with this Buck Knife we're cutting the submission period :)


Great imput everyone! Now it's up to John (neuroanatomist) to select his favorites and continue to the finals.


Thanks!

[HDNitehawk]

So with this Buck Knife we're cutting the submission period :)






Jan: I guess its time for John to pick which submission he thinks really have the edge....maybe slice out the ones he wants...


I suppose we should hone up on our voting skills....


Now were waiting on John to get to the point....


Sorry I couldn't resist...

[neuroanatomist]

Point taken, literally and figuratively. List of finalists sent to Jan, who should hav the voting up soon. Great submissions, everyone - choices were tough! One thing I really liked is that many of you went out and took new shots for this, thanks!


--John

[Sheiky]

Sorry I couldn't resist...


I liked it ^^



I suppose we should hone up on our voting skills....


Yep you do! The finalists are selected and the poll is now online for 3 days. Please vote and don't forget to congratulate the finalists ;)

[Andy Stringer]

I'm going to resist the puns and just congratulate everyone for a great variety of images as usual.


Make sure you vote before the cut-off time.

[Rocco]

Hmmm.. apparently after changing my password I'm "imported" heh. Anyway.. I think we should give this one to erno? Last I checked I was in second and he had 20% more votes than me.

Lol, yeah Erno James was definitely going to win this assignment.
I'll try to fancy up the starting post and look into how the poll works on this one. I say let's give it a few days to settle down, I will contact Erno James(or he could contact me) for the next assignment, and we should be able to start fresh with a well deserved winner very soon. :D

Jan

[Tom Wertman]

I can't see the photos to vote for. Just the URL's. Any thoughts?

[Sheiky]

I can't see the photos to vote for. Just the URL's. Any thoughts?
That's correct. Most of the photos were hosted on this site. But with the new forum upgrade those photos are removed I think and so they do not show anymore in this thread.
Photos that are posted externally(like Flickr or own site) still do appear.
Before the forum migration Erno James was definitely the favorite in the poll, so in the next assignment we'll make things alright.

[ddt0725]

Congrats once again, erno!!

[HDNitehawk]

It looks like the competition was CUT off early.

Gratz Erno, I thought that you had a really cool pick

[Kayaker72]

Ha :D

Congratulations to all the finalists. Enro, great shot.

LMAO. Razor sharp wit on this forum. No hacks here.

[erno james]

Well THAT was exciting! it took me almost a whole day to figure out how to reset my password to make this post. I think reading my Canon DSLR manual cover to cover was an easier task.

Hey, thanks for the kind comments on my shot taken of the sand dunes at Death Valley. Morning light made those dunes memorable for sure. As for the NEXT assignment, the topic will be.....GLASS. This one is open to interpretation; I am amazed at the creative minds that browse this site. To get us started, things like FAST glass, a BEER glass, or STAINED glass are but a sample of ideas. Happy shooting everyone! -Erno James

Hihi!:D
I'll be making a new assignment as soon as I can Erno, thanks;)

[HiFiGuy1]

I would love to see the shots everyone has made and submitted, but only some of them are visible to me. All the ones in the finalists post at the top are just text with no image. Do I have a setting wrong, or are the links broken?

Hey, no your settings are ok. This is an old thread. Most of the pictures were hosted locally on the old forums. Since the forums were migrated to new software all those files have been removed. Unfortunately that's the case for a lot of photos on this forum now, not only on this thread.
The photos that were hosted elsewhere (Flickr, Picasa, own website etc) are still available.
Hope I informed you well enough.

Jan

[HiFiGuy1]

Thanks, but that is a bummer. The winning shot seemed like it got lots of acclaim. I would love to be able to see it.

[Rocco]

Maybe we can convince him to post it again? It really is a great shot.
