![]() ![]() ![]() I have another helicopter photo where slight artifacts can be seen even when the image is a 14-bit RAW (they can still occur under the right conditions but the effects are lessened due to the use of an anti-aliasing (AA) filter on the sensor.īecause the raw converter (not Lightroom) I used to process this photo doesn’t have local adjustment capability, I exported the image to JPEG before making final adjustments using Viveza 2 as a Paintshop Pro plug-in. To further clarify, there are banding issues caused by the camera (as explained here) and there are those amplified and made more pronounced as a direct result of editing. You can see the spiral patterns (“banding” being the technical term to describe this occurrence in digital images) radiating from the chopper to the rest of the image. The problem I’m talking about are the spiral artifacts after I’ve applied local brightness and contrast adjustments to the white and red colored part of the helicopter body. I’m writing this post not to review this tool but to highlight a problem I’ve encountered sometime back (visibility pronounced under the right conditions) with the Viveza tool, and how support staff resolved the (annoying) problem in less than 48 hours, in two emails. It began with the Viveza plug-in that made local adjustments possible (Lightroom offers a similar tool by way of the Local Adjustment Brush but early implementation isn’t nearly as smooth as Nik’s U Point technology). CE has a semi-hidden history tab too.I am a huge fan of Nik Collection professional photographic tools and have only Google to thank for making them really affordable when they bought over the company. To import the presets, see here - they'll live in /Users/yourname/Library/Preferences/Google/Color\ Efex\ Pro\ 4/ImportedPresets folder on a mac. Hierarchy of effects' stack can also be changed and thus plenty more variations are possible. Most if not all are meant to be used together with U-points, otherwise pretty useless for instance I recurred a lot to the glow effect, but the reality was that more often than not with just u-points to very specific areas, as I mentioned before it's silly but there's no way to save those u-points. You've got to understand that many of them were developed working on some specific look/batch/context/experience, plenty of times directly with unrefined (no time to cut baby's nails man?!!) base image, sometimes darker, sometimes brighter, more constrasty, more bland, etc. only luma and chroma tweaks without masks), convert Davinci's base trim_lut0.dpx to png or tif, apply your recipe and then create an timeline with the file and extract the grade's LUT in Resolve =)įinally, attached are 41 presets - the ones managed to find - I created on CE long time ago plus a couple charts for testing. If there is something you'd like to apply to a video, you can save a recipe (as long as there are no vignetes, sharpening, etc. I found to be useful to mark the favourite effects (yellow star) so they're easier to locate. in Pro-contrast the effect is not activated unless you create either " " or "-" u-points. Also U-points behave differently depending on filter, e.g. You can export your recipes and backed them up, shared them, etc. basically there's no way of creating a U-point "memory". ![]() When you save a recipe, U-points are not saved with it. Whenever I say u-point I mean control points, I'm used that way these points behave a bit like add or/and subtract circular gradients' masks (with selectable ratio/size and transparency/power) but they also are very sensitive to where they're placed, a bit like a spot light (mimicking a 3D behaviour) within the confinement of a 2 space. In Dfine the more manual noise's patches you select the better the results, BIG difference, it's also worth tweaking the advanced controls. Mind you some things: when you save the image in standalone mode it will overwrite the original, so better make a copy beforehand. Some good introductions by Northlight Images ![]()
