![]() Stan Sholik is a writer and photographer in San Clemente, California. A 30-day trial of Nik Collection 3 by DxO is available. I really like the way the software helps you applying these corrections the easy way. After using Viewpoint 3 for a while, I won’t switch back to manual corrections in Photoshop soon. The collection retails for $149, and upgrades are $79. Viewpoint 2 was on my computer for a short period of time, but I switched back to correcting everything in Photoshop again. The new Perspective Efex module is one of the eight plug-ins in Nik Collection 3. Other sections of Perspective Efex correct horizontal and vertical lines, tilting buildings, and even flatten full-frame fisheye images. The unique ability of this plug-in to correct a common issue quickly makes it worthy of a closer look. Volume deformation is only one subpanel of the new Perspective Efex tab in Nik Collection 3. Even when the diagonal adjustment provides the better correction, you may decide the horizontal/vertical adjustment looks better overall if curving is too noticeable. This is most obvious when there are strong horizontal lines in the image, but it’s also visible in the repeating patterns that can be found on floors. With diagonal adjustments, the image is not only cropped, but lines become curved. In this case the diagonal adjustment worked better (right). With some images it is difficult to decide whether a horizontal/vertical or diagonal adjustment is more appropriate (left). These are most useful to reduce some of the correction if the original image becomes too cropped to show all of the relevant content. Two sliders are provided for fine tuning the correction both horizontally and vertically. When you select it, the image is processed with a default horizontal correction based on EXIF information in the digital image file. It’s located to the left in the Volume deformation subpanel. If heads or objects near the edge of the frame appear stretched or flattened, then first try the horizontal/vertical icon. HOW TO TAME DEFORMATIONĪpply the volume deformation correction by selecting Perspective Efex in the Nik Selective Tool 2 toolbar in Photoshop or by selecting Photo > Perspective Efex > Edit in Lightroom.ĭepending on how the image is deformed, Perspective Efex provides two methods of correction: horizontal/vertical and diagonal. With the release of the Nik Collection 3 plug-in from DxO, you can now correct volume deformation in Adobe Photoshop, Photoshop Lightroom, Photoshop Elements, and DxO PhotoLab.įor this tutorial, I used Perspective Efex in Photoshop and Lightroom on Windows and iOS systems. Previously this effect could be corrected only with the use of ViewPoint from DxO Labs. Volume deformation arises because a three-dimensional object cannot be exactly mapped onto a two-dimensional plane, such as an image sensor. These abberations exist even after applying lens corrections in editing software because they’re not the result of optical lens distortions but due to an effect called anamorphosis or, more commonly, volume deformation. This is especially apparent when a lack of space forces you to use a wide-angle lens for a group photo or wedding party. The starting frame of the cropping function sometimes cuts off those gained pixels which can be valuable.If you’re using lenses 24mm or wider, you’ve likely noticed unnatural effects at the edges of your images. On wide-angle photos, PhotoLab recovers much more lateral information than other software and direct JPEGs (especially for photos taken with cameras applying digital corrections). – Hold down the SHIFT key (Windows and Mac) to modify the frame while preserving these new proportions ![]() When carrying out new operations on the frame of this image, it is no longer necessary to press the key. Unconstrained mode becomes permanent for this image. – Pull on a handle of the edges to limit the direction – Pull on one of the corners of the dotted frame OR – While holding down the CONTROL / SHIFT key 2- A combination of keys allows you to quickly switch to an unconstrained frame, there is no need to select the “unconstrained” option
