AdoramaTV, host Diane Wallace invites you to a very exciting event - the 3rd annual Adorama Street Fair
, called Sunday Family Fun Day, in support of the Boomer Esiason Foundation to fight Cystic Fibrosis. The event is free and and fun for the entire family. Last year's festival attracted more than 20,000 attendees.
Sunday Family Fun Day will be held on Sunday, June 23rd from 10am to 4pm on 18th street between 5th and 6th Avenue in New York City. Taking place right out front of the Adorama store, you can participate in fun games and activities. There will also be a live petting zoo as well as food and beverages. Come inside and explore the Adorama store and you will be sure to find a plethora of discounts and you will have the opportunity to speak in person with some of the industries top camera and electronic brands including: Canon, Nikon, Sony, Panasonic and Adobe. Visit the Adorama outdoor Learning Center tent and take advantage of the free photography clinics. Additional highlights include, celebrity appearances, prizes and raffles.
I recently led a workshop on tasteful HDR up in New York City for Adorama. In fact I'm working on a new eBook on the same subject.
Here's two shots from the day… behind the scenes to come soon.Flat Iron Building

OK, prepare to be temporarily confused (but not for long). A lot of terms are used to describe image resolution. The problem is that many people (and companies) use the wrong terms, which (understandably) leads to a great deal of confusion. Let’s take a quick look at the most common terms and their accurate meanings. Knowing how to describe the resolution of images and output devices will help you make the right decisions when purchasing or choosing gear to use.
Dots per Inch (dpi)
The most common term used to describe image resolution is dots per inch (dpi). Although you’ll hear it used for digital cameras and scanners, it is really only appropriate for printers. As a measurement of output resolution, dpi is fairly straightforward.
To determine dpi, it is necessary to count the number of dots that can fit in a 1″ × 1″ area. A higher dpi can mean smoother photographs or line art; for example, newspapers tend to use around 150 dpi, whereas magazines can use up to 600 dpi. Consumer printers easily print at 600 dpi or even higher, which can produce extremely good results (when using the right paper). An increase in dpi can produce even better-looking images. You’ll see (and hear about) dpi used a lot, but it solely refers to print and physical output.
Pixels per Inch (ppi)
When you view your images on a computer monitor, you are seeing pixels displayed on your screen. Computer monitors use the concept of logical inches. Originally, the Mac OS most commonly used 72 pixels per inch (ppi) to match the concept of the printing idea of 72 points per real inch of paper. The Windows OS has traditionally used 96 ppi.
As computer monitors and portable devices have evolved, they’ve advanced to support variable resolution settings. As such, the actual ppi for a screen can vary greatly depending on the physical size of the screen and the resolution being used by the computer’s graphics card. For example, modern laptops often use resolutions between 100 ppi and 140 ppi, and devices like an iPhone can jump all the way up to 326 ppi to make images crisper on the small screen.
Worry less about the ratio of pixels per inch on your screen and simply accept that the standard measurement of resolution in Photoshop (and most computer programs) is ppi. When talking about displayed graphics, its ppi, not dpi.
Samples per Inch (spi)
Although scanners are less common than they used to be, many professionals still use them to load sketches, photos, and original negatives. Manufacturers often tout the dpi capabilities of their scanner. This is inaccurate. Scanners don’t use dots, they use samples. A sample is when a scanner captures part of an image. Samples per inch (spi) is a measurement of how many samples are captured in the space of one inch. In general, an increase in sampling leads to a file that is truer to its analog original. However, there is a threshold: Once a certain amount of information is surpassed, human senses (and electronic output devices) cannot tell the difference.
Consumer-level scanners can capture optical resolution ranging between 300 spi and 4800 spi. Professional devices can capture significantly higher optical resolution. If you’re working with a large image, a lower number of samples is fine. If you’re enlarging a very small image, a large number of samples is crucial. More samples per inch translates into more information available as pixels, which can then be harnessed in output when they are converted to dots in the printer. So if your scanner’s software specifies dpi, it really means spi, but you can see how the two are closely related
Lines per Inch (lpi)
In professional printing environments, you’ll often hear the term lines per inch (lpi). This is from the traditional process where images with gradiated tones (such as photographs) are screened for printing to create a halftone. This was originally performed by laying film with dots printed on it over the film before exposure. In the digital age, this process and these terms are used less often, but it is still good for you to have a basic understanding. These days, the work of converting an image to lines is performed by an imagesetter. The dots are arranged in lines, and the lpi measurement refers to the number of lines per inch. An increase in lpi results in smoother images.

My friend Scott Bourne wrote a great post on getting started in photography. It is a must read for anyone who doesn't consider themselves a photography pro.
My favorite from the list is
"5. Don’t try to learn everything all at once. You don’t have to become an expert photographer, post-processor and printer all in the same week."

The folks over at NPR have a great article on Photorealism.
"Can you guess which one is a photo and which one is a painting?
Quartet by Ralph Goings
If you're going to do a painting that looks exactly like a photo, why even paint it? When asked this question in a written Q & A, photorealist painter and octogenarian Ralph Goings responded, "What I'm about is making paintings, and my camera is one of the tools I use. It's the artist's job to take the painting beyond the photograph."

In the category of sounds weird but is actually quite cool, we have a time-lapse film put together of a recent mural built from Post-It notes. It's a portrait of Steve Jobs built by a team of artists.
The whole project was created using:
- 4001 post-its
- 400 m of ducktape
- 6 hours of work
- Filmed with an iPhone4
- Edited with iMovie on a MacBook Air
