Viewing photographs on the iPhone 4’s 326dpi “Retina” display is absolutely incredible. It’s a 1990’s era dream come true. Text is easy for any display to render sharply but rendering fine photographic detail is quite another story. For many of us, phones and iPads have become portable portfolios that are fluid and easy to show people while on the go. Apple’s new iPhone 4 takes portable image viewing to a new level, but there are some details towards getting optimal results that are worth mentioning for demanding users.
In the past, zooming in on iPhone images led to disappointing results because it just an enlarged low resolution photograph, kinda like zooming past 100% in Photoshop or past 1:1 in Lightroom. When you sync a high pixel count image to an iPhone, iTunes “optimizes” images for the phone by lowering the pixel count and re-saving a unique JPEG for the phone. This process can lower the image quality and sharpness significantly thus many pros have been disappointed with image viewing on previous iPhones. It felt low resolution to begin with and even worse when zoomed.
With the release of iOS4 came a new iTunes image optimization routine designed to improve image viewing especially on the iPhone 4. From my tests it appears that iOS 4 now stores images at 1920×1280 pixels with a medium amount of JPEG compression. If images are even just slightly larger than this pixel count iTunes will resample images which results in a loss of image sharpness. If images are lower than this pixel count they will appear pixelated when you zoom in on them.
For photo geeks wanting to get the very best image quality on their iPhone 4, I suggest (more…)
(with comparison to Epson x900 and HP Z3200 printers)

Canon’s latest generation of large format printers offer an exciting mix of refinements. The 44″ 8300, 24″ 6300 and 6350 (which includes a hard drive) are referred to as the “x300 printers.” I’ve had the pleasure of testing both the 8300 and 6300 printers alongside others as they’ve come to market. Instead of writing a super long in-depth review, I’d like to offer this relatively brief and to-the-point synopsis of my own findings of these printers. I’ll spare the details as to what comes in the box and focus on the points that experienced users are probably looking to hear.
Before I begin, I should say that I get my hands on a huge variety of printers in my work traveling around as a color and workflow consultant. Not only do I own Canon, Epson and HP printers in my own studio where I print my artwork that I show in galleries, I oversee a large base of clients all over the world that use everything from Durst silver halide printers to 20 foot wide Scitex solvent printers. I’d like to think I’m in a decent position to have a bird’s eye perspective of the industry as a whole and I strive to be as unbiased as I can with my observations. I choose to appreciate the differences between different products and try to avoid the type of brand loyalty that seems so common in our industry.
New inkset improves gamut substantially
The most significant improvement with these printers lies in Canon’s new Lucia EX inkset that increases the color gamut by about 20%. All 12 of Canon’s inks are newly formulated with smaller pigment particles and increased polymer encapsulation. The smaller pigment particles reduce reflection (more…)
Dan Winters’ unique ability to sculpt with light has long been a personal inspiration of mine. Now more than ever his work is everywhere. He’s won more awards and contributes to more magazines than I can list. When I was in an airport a few weeks ago I glanced across a wide walkway full of people and caught a glimpse of this Time magazine cover of Tom Hanks on a newsstand. In that split second from some 80 feet away I just new it was Dan’s image. His lighting is so dramatic, so distinct (yet never the same) I just knew it was his.
Austin American-Statesman photographer Jay Janner recently made this portrait of Dan in his Driftwood, TX studio – the first of it’s kind in front of Dan’s handcrafted photo booth in his Driftwood, Texas studio.
FLYP magazine published a great article on his work and career. Highly recommended viewing. Included in the article are two videos where he talks about his devotion to photography and what makes a great portrait.
If you haven’t already I’d encourage you to spend some time at Dan’s website. Better yet, order his book Periodical Photographs from Aperture.
I’ve always been a fan of high-end displays like those from Eizo, Barco, Quato, NEC and the like. At the same time I recognize that these pinnacles of technology are hard for most people to justify. I love discovering displays that are affordable yet meet the demands of the most finicky printmakers. Simply put, some ~$800 displays hold up darn well against $2000+ displays when they are well calibrated and it’s this “best value, high quality” category that I get excited about and often recommend to my clients.
All of these displays use an LED backlit lightsource, IPS LCD panels and eco-conscious materials. These first two technologies are crucial for demanding professionals. The LED lightsource provides consistency across the screen, a boost in color gamut, power savings, lower heat generation and can achieve the lower luminance (brightness) levels that print professionals need. The IPS LCD panel provides a wide viewing angle so that the viewer doesn’t experience the density shifting that’s become so common with laptop and most LCD displays today that use the less expensive TN LCD panel technology. A lot of companies (more…)
I’ve been managing color on Lightjet, Durst, ZBE Chromira, Agfa, Kodak and Noritsu machines since the mid-nineties. As a color management consultant with a background in photo lab work, this is close to my heart and an area of specialty for me. I’ve traveled across several continents consulting with some of the most demanding photo labs in the industry. I’ve also enjoyed a close relationship with Noritsu for over 10 years and have lectured, consulted and trained with them internally. So perhaps I am in a decent position to respond to some comments that I am surprised to hear people make on forums and elsewhere.
“If you want a fully color managed workflow I don’t think any silver halide process will provide that” – anon
Safe to say I’ve implemented fully color managed workflows with every silver halide machine on the market. It’s totally doable and has been for many years, but unfortunately some exceptional know-how can be required. (more…)
1 ) Make adjustments in the proper order working from the top down. Set white balance first, then Exposure, etc. Don’t skip around.
2 ) Ignore the midtones when adjusting Exposure and consider only the white clipping point. One must ignore the midtones as they will be adjusted via Brightness later in the workflow. If some whites are clipped at 0, option/alt drag the Exposure slider to the left until all colored pixels are removed.
3 ) Skip or be modest with Clarity. While lots of clarity creates a look that’s trendy right now, you might be surprised at how poor it can look when printed and compared to other images. I find that small prints (4×6, 8×10, etc) don’t need any clarity but larger prints (20×24, 60×94, etc) benefit from greater amounts. It’s worth considering scaling the amount of clarity with the size of a print.
4 ) In HSL, adjust Luminance first, Saturation second and Hue last. Be modest with adjustments and zoom to 1:1 looking for problems along edges.
5 ) Don’t skip correcting for Chromatic Aberration in the Detail panel! Chromatic Aberration is one of the most overlooked features yet it can easily improve the sharpness of an image in addition to removing unwanted color fringing. Hold down the Option/Alt key and look at the corners of your frame at 1:1 while adjusting chromatic aberration.
6 ) When applying a dark edge vignette, use a Post Crop vignette with a feather amount close to 80. The default feathering value of 50 is too low.
7 ) Pro users should consider making custom DNG profiles for their camera(s) with the XRite ColorChecker Passport. If not, the “Adobe Standard” is more likely than the other profiles (Camera Landscape, etc) to render pleasing results with a wider variety of images.
8 ) Develop images in Color mode before switching the treatment to Grayscale. Not only will the final grayscale product look better but the image will be ready for color printing should you decide to do so in the future. After applying a Greyscale treatment, re-adjust contrast (if necessary) and use Grayscale Mix (in the HSL panel) to simulate in front of the lens filtration (yellow filter, red filter, etc). This greyscale procedure will yield better results than a haphazard one.

9 ) Use Snapshots to save different versions of your images (ex: grayscale and color, cropping for different aspect ratios, etc). Saving snapshots with numbers is quick and can show a progression of development (when appropriate). Example: 1, 2, 3, 4color, 4grayscale, Import.
10 ) Uncheck the “Apply auto grayscale mix when converting to grayscale” checkbox in Lightroom’s preferences under the Presets tab. Auto=Yuk.

11 ) Set the background to white. You can do this by right-clicking (or control-clicking) on the background color around the image area when set to “Fit” to screen. While a white background may not be as pretty as the default dark gray, it will give you a better idea as to how an image’s highlight and mid-tone densities will appear when printed. A juxtaposition with paper white is critical. Toggle between white and dark grey if you like, but always view and adjust with a white background before printing or exporting.
12 ) Print! Image development can only be mastered by producing gorgeous prints. A lot can and will be learned along the way.
Fortune Cookie of the day: Moderation is good for all things in life, especially with clarity, saturation, vignetting and HSL adjustments.
Eric Chan has generously responded to a need in the color community by bringing his “Convert to MonacoLAB” application to the Mac OS. Convert to MonacoLAB allows color geeks to measure Bill Atkinson 1728 or 4096 RGB printer profiling targets in either MeasureTool or ColorPort and convert the measurements into the LAB format that MonacoPROFILER requires.
Unlike the previously popular “Extract Monaco LAB” applescript, “Convert to MonacoLAB” is Snow Leopard (Mac OS 10.6.x) compatible. The Windows version is compatible with XP and Vista; it should also be compatible with Windows 7, though it has not yet been tested on that platform.
“Convert to MonacoLAB” uses a convenient droplet that allows the user to drag and drop a measurement file onto the droplet icon for processing. The processed measurement file retains the original file name and conveniently adds the “MP” suffix at the end of the filename.
You can read more about and download the Mac and Windows versions of Convert to MonacoLAB at Eric’s website. Here’s the direct link to the Mac download and the Windows download.
I’m a big fan of Bill Atkinson’s 1728 profiling targets and have been using Eric’s application in Snow Leopard to get measurement data into MonacoProfiler for generating printer profiles. I’m also a big fan of Eric’s work at Adobe. A big thanks to him for making this utility.
I’m pretty impressed with LR3’s new demosiacing, sharpening and noise reduction in LR3’s new process rendering. To the right is an image taken at this month’s workshop in Mono Lake (larger view). This is a 15 second “star points” exposure taken at 1600 ISO with a 5Dmk2. Below is a side-by-side detail comparison, processed in LR2.5 on the left and LR3b on the right. Click the image below to view at it’s full resolution.
Tom Hogarty, Lightroom’s Product Manager, has lots to say about this beta in his blog. In it he says:
“We’re only halfway through our noise reduction efforts but believe that you will be very pleased with the results so far. We’ve actually disabled the previous Luminance Noise Reduction so that you can focus on evaluating the Color Noise reduction implementation.”
I’m finding a few reasons to actually increase luminance noise reduction on high res long exposures in low light, so I’m yearning to see these sharpening tool evolve a little further from where they are in this beta. But I’m impressed with the results so far.
Tom also points out that images previously developed in previous versions of Lightroom will initially appear the same in LR3 with a warning triangle that appears above the upper left hand corner of the Histogram. If this triangle is pressed, the image will be re-rendered using LR3’s new processing, including the new demoasiacing, sharpening and noise reduction algorithms. The screen grabs above were taken before and after clicking this triangle using LR’s detail panel defaults. It appears that LR3’s new process quality improvements are best seen on high ISO images, especially those from 20+ megapixel cameras files.
