I suppose musings like this are very common among Apple haters. Basically the complaint boils down to:
“325dpi? Bah! Even a 1986-era laser printer does 300dpi and my newspaper does at least 600dpi. Until you get there, the print is smudgy and causes eye-strain.”
The facts in the Apple’s advertising blurb are 100% correct. If you have a beef, don’t take the advertising head-on. The whole thing is essentially a misdirection .
What a crock of shit.

The film effects section of my last article on Aperture presets reminded me that I really like the film effects in nik Color Efex Pro and nik Silver Efex Pro.
I thought I’d try to emulate them in Aperture with a set a presets, starting with black and white film.
Download the presets here. Current version at time of this writing is 0.4.
(Note that my friends of Aperture Users @ Flickr are thinking of creating a website to house presets so I don’t know how long I’ll keep updating this. In the meantime, I added Pavel Sigarteu’s SinCity, El TiDY’s presets, and Ian Wood’s Aperture 2 Image Presets Project to the download.)
In order to show the B&W film effects, I hacked in an extension to my IMG Mouseover plugin. Above the image there’s a control panel where you can click to see the effect of the preset (and compare it to Silver Efex Pro):
Tagged, Financial District, San Francisco, California
Leica M8, Cosina-Voigtländer NOKTON 35mm F1.2 Aspherical
1/30sec, ISO160, 35mm (47mm)
Click on the controls above to test the different film presets. Mouse rollover contain images processed in Nik Silver Efex Pro.
(Note that Aperture has decided to have a brain fart and replace all my photos even if they haven’t been changed at all. This breaks the images in Flickr. I tried my best to fix this. If any are broken or incorrect, please tell me in the comments below and I’ll fix them.)

Anyone who has taken a flash photo of their cat is aware of the cloudy yellow/green reflection in their eyes. Such was a topic of discussion on Flickr Technique.
The reason for this is that cat eyes have a reflective coating in the back of their eyes called the tapetum. Nocturnal animals have this so that light passes twice through the transparent rods/cones of their eyes creating a second opportunity to absorb the photos and resulting in better night vision—at the price of some acuity of vision because of the folded optical path. Light comes from two distances and cats are far-sighted anyways.
Pretty neat piece of evolutionary engineering.Continue reading about red eye in photography after the jump.
