My Nieces

So Easter was here and I got to spend time with my 2 fav nieces. My only ones but that's not the point.

Yes she was crackin' eggs on her head. Might explain a lot...

Who knocked her teeth out?

Can I get that dress in my size?

Anyway, I really liked these pictures, candid shots are my favorite...and they're cute, which makes the pictures better. Good job.

Who knocked her teeth out?

I'd assume it was her somehow. Just baby teeth though.

Thanks Nicole.

I'm calling Chris Hansen. :nono:

nice pics! shot with the 50mm?

Sigma 18-50 F2.8 on the first...

Now get this, Sigma 70-300 APO. That APO is what made it so nice. The last three were on F5.6 all the way at 300 and cropped. ISO was...200 I believe.

APO is to minimize chromatic aberration right? not too familiar with that term.

it's Sigma's nicer glass like Nikon's ED and Canon's L. It kills the flare and ghost pretty much what you said. Plus my custom settings on the 20D.

ah i see, thanks for the info!

2 are the same and 2 are different. Thanks for the comments ya'll!

LOL!!!

How did you do the B&W with color? Photoshop?

Definitely. I was bored at work. I'm gonna miss that job...

Chromatic aberration... optical materials have different refractive properties depending on the wavelength of the light. The index of refraction ie the amount that the material bends the light is higher for shorter wavelengths so light at the violet/blue end of the scale is bent more than at the red end of the spectrum. At relatively short focal lengths, this isn't too much different as the light is being bent only a short way but starts to matter when you start using a telephoto ie f>200 mm or so...

In a classic achromatic lens, you have two elements of differing dispersions to cope with the different refractive indicies so you end up with light at each end being at the same focal length (ie red and blue are in focus!) - but you may have issues with the green light (splitting the spectrum into RGB).

Think about the Pink Floyd Dark Side of the Moon cover with white light being split by a prism ie the refraction index differs through the prism so that each color is bent to a different amount (and thereby splitting the colours like a rainbow!) and then having to bend them back so they focus on the CCD or film... which is why you end up with colour flare (the light is not converging at the same point) or ghosting as the different colours are refracted to different angles (which causes bleeding of color at transitions) in an achromatic telephoto...

Adding a third element to make the three colors focus at the same point is possible (apochromatic) but it isn't as it easy as it sounds as other colours may be out of focus and one of the elements has to be reasonably exotic to do so -> but better than a standard telephoto achromatic lens... and also why they are heavy and expensive than achromatic lenses..

There are lots of other distortions that you get when you start cranking up the power on lenses... and I defer to those who understand light better than my year 11 physics class which I took before most of you were born!

Oh man, I havent laughed this hard in a while. :rofl: That reminds me, there are sooo many hilarious parodies of him on youtube, including an actual "predator" (like the alien hunter thing).

That's not "Where the hell is Predator?" is it? Cause that video had me rollin'!!! :lol:

This one? :rofl: :rofl: :rofl:

No, this

You have to go to wherethehellismatt.com first and check out the whole story to get the spoofs.

haha thanks for the lengthy explanation. i should have been more clear, i meant.. i wasn't too familiar with what "APO" was. thanks tho!
