#Aperture software company manual
Indeed, I now regret deleting some photos that I'd written off as unsalvageable because of axial chromatic fringing.ĭespite the manual labor, Adobe is still happy with the new feature and with another defringing feature that can fix some lens-flare issues. It's a bit complicated, but it definitely retrieve some shots. "It's up to the photographer to use those tools to distinguish between the fringe color and regular image color," Tom Hogarty, senior product manager for Lightroom, told me.įortunately, Adobe provides local adjustment tools that let you walk back or eliminate the defringing in areas of the photo you need to protect. (Click to enlarge.)įixing real-world shots can be more complicated since you won't want to lose the color in the the real green and purple areas, and manual work can be required. Here, Lightroom 4.1 was used to fix the axial chromatic aberration colors. This shot, taken with a Canon EF 50mm F/1.4 lens at its widest aperture, shows axial chromatic aberration in the form of green fringing behind the focus point and purple fringing in front of it. I used it mostly successfully to rid a test photo of purple and green fringes in a shot taken with my Canon 50mm lens, which is prone to axial chromatic aberration when shooting wide open at f1.4, but I had to crank the sliders to a pretty broad spectrum of colors to do so. Lightroom 4.1 has tools to get rid of this axial chromatic aberration using the new "color" section of the lens corrections panel. The problem often crops up when shooting with wide apertures, with objects in front of the focal plane being fringed in purple and objects behind fringed in green. But axial chromatic aberration can actually be a worse a problem in higher-end lenses that offer a wide aperture for high shutter speeds and a shallow depth of field. Lateral chromatic aberration can be minimized in high-end lenses by using special lens element materials and employing other advanced designs. Previously Lightroom could handle only a more common type called lateral chromatic aberration, but now Chromatic aberrations in general show as a fringe of colors plaguing high-contrast areas, and they stem from the fact that different colors of light take different paths through a lens. Second, the software now can now correct a second type of chromatic aberration. The eyedropper tool can select the colors, the "amount" sliders govern how much colors are desaturated, and the hue sliders govern how broad a spectrum of colors will be treated.Ĭhromatic aberration and defringing fixes This new panel can fix axial chromatic aberration in Lightroom 4.1. Plus, the new highlight and shadow controls that debuted with Lightroom 4, coupled with judicious use of the clarity slider, often get me the image I want without any HDR hassle in the first place. But then I prefer the understated use of HDR to address exposure range problems, not the over-the-top style some use to make gritty, grungy, surreal, and often eye-catching images, so I'm not sure if this tool is for the HDR enthusiast crowd.

In my tests with the Lightroom 4.1 beta, I have found the HDR feature useful in the classic problem of showing both bright stained-glass windows and dark cathedral interiors. Regardless of how you obtain your HDR file, though, Lightroom now can edit it, which is nice for people who prefer its editing controls for tone and color.Īdobe, naturally, recommends using Photoshop whatever tool you use, the company recommends importing a "flat" HDR image in TIFF form, then using Lightroom for the tone-mapping process used to decide which parts of the image should be dark and which bright. Photoshop can produce these files, though HDRsoft's Photomatix got the jump on the market. More on that competition and customer angst later, but first, here's what's up with the new features in Adobe's $149 program.įor Lightroom 4.1, the first new feature is the ability to import HDR (high dynamic range) files, typically made by combining multiple photos that span a broad range of exposures.
But this market is Adobe's bread and butter, and the company is working hard to turn the crank for improvements as fast as it can. Adobe Systems released Lightroom 4.1 last night, supporting new cameras and lenses, squashing some bugs, adding a couple of notable features - and in at least one high-profile case, contributing to the angst of a customer of Apple's rival Aperture software.Īperture beat Lightroom to market and leapfrogged it with lower pricing in this category for higher-end photo editing and cataloging software.
