03 Capture One sharpeningĬapture One Pro 7 can also export images at different sizes, but doesn’t offer a choice of interpolation options. If you’re exporting images for on-screen or online use, this is the one to go for. It gives reasonable results for both enlargement and reduction, but favours smooth tones rather than sharp detail.īicubic sharper is designed specifically for resampling images downwards, and this image, right, is much sharper than the other two. In fact, though, it’s only marginally sharper than the Bicubic setting, shown in the centre.īicubic resampling is a kind of default amongst image-editors. The default Auto result is on the left, and you might expect this to automatically choose the best resampling method for the size change being applied. 02 DxO Auto vs Bicubic vs Bicubic sharperĪnd here you can see the results (remember – you can click on these images to see a full-size version). These aren’t sharpening tools – this menu simply changes the way DxO Optics Pro calculates the pixel values. They’re on the drop-down Interpolation menu, which I’ve circled in red. 01 DxO export settingsĭxO Optics Pro 9 offers different resampling options when you export a file – if you’ve used Photoshop or Elements to resample images, you’ll recognise them straight away. I’ve used the same test, and the same image I used last time (above), exporting the full-res file at a height of 1024 pixels for web use. In part 2, I want to find out whether the same applies for DxO Optics Pro 9 and Capture One Pro 7. In part 1 I compared the results from Aperture (which has no export sharpening), Lightroom (which does) and the dedicated Perfect Resize plug-in. Export sharpening is a setting that’s often overlooked when you generate images for online or on-screen viewing, but it makes a big difference to how sharp your pictures look.Įvery time you resample an image, you introduce a degree of blur because the software has to interpolate new pixel values – and this applies when you’re downsizing images for web use too.
