I like everything so far. it just never does anything for perspective.

none of this matters to me, as my little brother is a GoPro sponsered athlete and i just wait for his hand-me-ups. its only fair as he was skiing on my skis when he 1st got sponsered. that was almost 10 years ago, now he's got his own model of skis now.

anyway, currently, cliff edges look like beaches compared to reality.

asperical, is that like a-typical or a-symetrical?

I have been wanting to get a GoPro for a while now so I am glad to see the new 3 comming soon, guess I'll get that one...

Aspheric

An aspheric is a lens whose radius of curvature changes with distance from the center of axis. Spherical optics maintain a constant radius of curvature. Aspherics correct geometric aberrations from high order terms that spherical optics don't account for because of the assumptions made in geometric ray tracing formulas. Aspherics, however, due suffer from not being to correction aberrations due to index of refraction changes across the visible spectrum called chromatic aberrations.

You need to come work in lithography

I am "sort of", in some of my work we are pushing limits of coherent imaging to 12 nm.

12nm will be our next size when the machines are perfected.

that would be 100 eV photons and can be achieved with Schwarzschild-optics incoherently. If the coherent imaging works at 12 nm, there would be nothing limiting (other than an x-ray lasers and materials compatibility) to get down to 1 Angstrom (0.1 nm).

I thought this was a requirement to join ADV forum...

I didn't even get into the nonlinear optical response of photoresist to 193nm ArF laser light for small scale lithography.

Lets see..... I hook up the GP3 to the bars, hook up the Wifi, place a robotic control system on the bike and I can stay home drink beer and ride?????
