iphone programming

iCodeBlog is an excellent site for iphone programming tutorial. You need mac hardware to use iphone sdk or you can use your own x86 hardware to create a hackintosh. You can find all the information in InsanelyMac forum. I found Cocoa® Programming for Mac® OS X, Third Edition book to be a great intro to Cocoa. The book is well organized, very readable, and has good examples. After reading this book, you’ll be able to start writing applications in Cocoa.

Pixel Packin’ Landing in DC

The phone rang yesterday to tell us our first stops on our Pixel Packin’ Pleasure tour has a few hundred folks already signed up. Darn cool, can’t wait to share what I’ve learned over the years and what’s new in the last month.

Which Came First, On or Off?

Many people have emailed to alert me to Errol Morris's latest article in the Times. In this one he's concerned himself with how our—well, how Susan Sontag's— interpretations of pictures might be built around incorrect assumptions.

What are we going to do without noise?

With the Nikon D3 having impressive pictures noise-wise at ISO 1600, 3200 and even 6400, it looks like the people who are totally allergic to noise will have an actual DSLR that can deliver them class leading noise performance.

Lighting 102: 3.3 - Balancing Flash/Ambient Indoors

When last we met, we talked about moving from the idea of balancing a nice, even, back-curtain of sunset light to dealing with a highly directional light source (and learning to use it rather than just fill it.) This week, we are taking it indoors to apply the same principles to light that is less directional, less intense and more diffuse.

Yes, The Aspens are Turning

Just a quick Sunday nite update from the road, yes, the aspens in Colorado are turning. The shot above was taken just after George Jardine and I crossed over Independance Pass coming out of Aspen (the town, not the tree).

Wednesday Inspiration - LeRoy DeJolie

I’m just a few weeks away from my Arizona workshop with the GAPW. We’re going to Page, Arizona to shoot the Antelope Slot Canyons and surrounding areas.

iPhone early adopters get your $100 credit FAST

Today Apple released the details on getting your $100 Apple Store Credit if you bought AND activated an iPhone before August 22nd.

Magnificent Surrounds

The class gathered about 9:00 A.M. in the morning and we hit the trail about 10 A.M. heading out to St. Mary's Basilica in Covington, KY. It's one of the most beautiful churches not only in Covington but in the entire Cincy area.

Diffraction & Photography

Diffraction is an optical effect which can limit the total resolution of your photography no matter how many megapixels your camera may have. Ordinarily light travels in straight lines through uniform air, however it begins to disperse or "diffract" when squeezed through a small hole. This effect is normally negligible, but increases for very small apertures. Since photographers pursuing better sharpness use smaller apertures to achieve a greater depth of field, at some aperture the softening effects of diffraction offset any gain in sharpness due to better depth of field.

Convert Color Digital Images into Black and White

With the proliferation of digital photography, people have now started to look at ways to recreate what film has done for them, including recreating a black and white photo. There are numerous ways to make a digital black and white, some include: 1. In camera filter - By changing a setting in the camera menu to take a black and white photo. Essentially this is a built-in color de-saturation method that removes the color information after the camera takes the picture. I won’t be covering this method in this article. Pros: Easy, simple and does not require any knowledge or post processing to create a black and white photo. Cons: Limits the contrast and dynamic range of the photos. In my personal experience, leaves the photo looking washed out or flat.
