Digital Imaging Tech
When it comes to digital imaging and photography there are a lot of variables. Trust our articles on digital photography technology to make sense of pixel counts, file formats and everything in-between.
A Milestone In Time Full HD video comes to digital SLRs  It was a fairly innocuous start. A hastily assembled, last-minute project conceived and shot in 14 straight hours, edited together in three hours (no time for color correction) and a quick posting to a blog with the link to the completed five-minute short. This was as close as you could get to a straight line from the camera to the web.

Stylize Your Images Using Digital FiltersThe difference between a technically solid photograph and a real winner that makes clients stop for a closer look is a matter of style  What makes winning images win? Apart from the opportunities and advantages that are afforded by huge leaps in digital technology, one point stands out, as always—style! Today’s light-meter technology helps ensure technically correct exposure, but it’s personal insight and style that bring the exposure to a higher level—being aesthetically correct! The same can be said for the aesthetics of composition, color treatment, focus, contrast, balance and every other aspect of an image that strikes your eyes and grabs your mind. Aesthetics and style help make an image stand out.Read More...

Hi-Tech Studio: Triggering The LightWireless flash systems give more freedom when it comes to creative lighting  There are two main categories of wireless flash control: standard optical slave triggering and the more modern and more versatile radio transmitter/receiver triggering. Both provide us with a variety of control over flash setups, whether it’s firing multiple compact flash units or the more powerful strobes and power packs.Read More...

Photoshop CS4 Takes Off Adobe alpha tester and all-around digital master Jeff Schewe takes us on a tour of the improvements to the new version of the Adobe Creative Suite, CS4  Yes, it’s that time again, another update to Photoshop, called by its full name, Adobe® Photoshop® CS4 (and, yes, there are regular and Extended versions again, with the Extended version designed for specialized image types and 3-D and multimedia). This represents the 13th time Photoshop has been updated (there were two .5 versions, so this is considered version 11).Read More...

New-For-Fall D-SLRs ReimaginedIn the lead-up to the huge Photokina 2008 trade show, there were a number of big new camera announcements—more megapixels and better image quality, and in the spirit of convergence, HD video makes the leap to still cameras!  This was a Photokina year, and Photokina 2008 included a number of exciting new camera introductions (even if they actually appeared a bit ahead of the actual show). On these pages, you’ll meet new low-cost, 20-megapixel-plus, full-frame D-SLRs from Canon and Sony, versatile new mid-range D-SLRs from Canon and Nikon, new D-SLRs with movie capability (and HD, no less) from Canon and Nikon, and 50-, 56- and 60.5-megapixel, medium-format entries from Hasselblad, Leaf and Phase One.

Go Large With High-Tech PrintersModern large-format printers are cost-effective and give you the opportunity to make exhibition-quality prints right in your studio  Many photographers are looking to control the entire process, from capture to output, these days for a number of reasons, including quality, price and turnaround for clients. While most studios have at least a 13x19 printer in-house, larger work is often sent out to a lab or service. Large-format printers have had the reputation of being expensive and demanding to operate, and it’s just one more thing to pull you away from the camera.

Megapixels: How Much Is Enough?Pixel count certainly plays a key role in photography, but we’re approaching a point of diminishing returns and potentially reduced image quality as more pixels are packed onto a sensor  It’s time for the “megapixel wars” to end once and for all. You can bet the march of technology will continue to give us imaging sensors with ever-greater numbers of megapixels, but for most photographers, more pixels won’t give us better images. Sure, more megapixels generally are welcome. But the reality is that we’ve reached the point where most photographers won’t benefit from more megapixels. Read More...

The Fall And Rise Of Medium FormatNew technology, a commitment to developing the very best image quality possible and a thriving rental market all have contributed to a renaissance in the digital medium-format category  It's no secret that the medium-format industry has experienced dramatic changes since the advent of digital. Open camera systems (think Hasselblad's H2 series) became closed, leaving players such as Phase One and Leaf no access to Hasselblad's systems. Additionally, the disappearance of beloved medium-format models signified harsh times in the sector as Contax, Bronica and Pentax fell by the wayside.

DPP Solutions: A Look At DNGThe DNG format was supposed to be the future, an open standard for RAW files that every manufacturer could use. Here's a look at how the revolution has panned out.  On September 27, 2004, Adobe announced the Digital Negative Specification (DNG), a file format that was supposed to unify the cluttered atmosphere of proprietary RAW file formats by offering a non-proprietary template that would act as a universal raw file. The DNG format was released, free from any legal restrictions or royalties as an open-source file for hardware and software designers to generate, process, manage and archive RAW images for any program, from any camera, and easily accessible as an archive at any time in the future. Almost four years later, DNG hasn't found the ubiquitous acceptance the industry had called for, but there's growing hope for the future.
