Zooming was only available in the Chromatic Aberration tab, which makes sense. Its three tabs are Vignetting, Perspective, and Chromatic Aberration. Next to the file list on the left is a tabbed section with correction sliders. Below the image are the camera and lens selection dropdowns and option buttons for geometry correction of barrel-pincushion, Fisheye, or none. Once you choose a folder, the image files are listed below the button, and clicking on one displays the photo in the main large window on the left.

The File menu didn't let me open a photo as I expected it might, instead, to get started, you click the 'Directory' button at top right. Interface PTLens's bare-bones interface uses a single window, and its non-standard control layout makes using it less intuitive than more polished apps. On first run, you choose your language from a dropdown, and are informed how many processors are in you system, e.g., 4 for a quad core.

When I run this, it asked me if I wanted to additionally install PTLens as Photoshop and Photoshop Elements plugins, which is a help. The Windows download is a ZIP you have to extract, and then you run a standard MSI that takes you through an installation wizard. You can also install PTLens as a Photoshop plugin, for Photoshop versions back to CS3. The installer is a tiny sub 4MB download. The Windows version works with OS versions all the way back to Windows 2000 or later, while the Mac one works on 10.5.2 and later systems.

A trial version only lets you work on 10 images. Installing PTLens is available for both Windows and OS X PCs, though the Windows version is at 8.9, while the Mac version is still at version 1.6. Let's see whether this $25 single-task program can still keep up with the big boys of photo adjustment.

#Ptlens software

PTLens's home page claims that it was the first software to automatically correct these kinds of lens distortion.

Lens physics also comes into play with chromatic aberration-those color fringes at high contrast edges, and with vignetting-the effect of darkening at the edges of the photo. This kind of correction is particularly important when it comes to geometry issues introduced by lens optics, such as pincushion (from wide-angle lenses) or barrel distortion (from telephoto lenses).

Camera calibration software maker DxO is a leader in this field, too, with its DxO Optics Pro 7. The foremost exponent of this technology has, unsurprisingly, been Adobe, with its Photoshop CS6 and Lightroom 4 apps offering leading lens-profile-based image corrections. Perhaps your camera system is in the PTlens data base or can be added.If you care about getting your digital photos correct-that is, looking as close to the scene you saw before you-lens-profile-based image correction is your ally. Consequently, most software only models radial distortion' 'Experience shows that the effects of radial lens distortion f(r) exceed those of torsional distortion g(r,О±) at least by an order of magnitude. (My script pinbarrel at my link below will be slow, but does allow for a r^4 term). But I think A=0, B=K1, C=0 and D=1, but IM is missing the r^4 term. Try comparing the order of terms in the two sets of equations. You should be able to use just K1 and K2 terms in Imagemagick to do the radial distortion correction. I would not know how, since the current IM model only seems to include radial distortion and not tangential (torsional) distortion. Is it possible to convert from one model (Brown-Conrady) to the PTLens model using some transformation equations,
