No control line, but there did add the luma and chroma adjustments, which makes it considerably better, at least for me. The masking in Viveza is still only the old control points. I don’t do black and white photos much so the only modules that interest me are the Viveza and HDR and, perhaps, the Color Efex. If you want to see more canaries with some imaginative talk (what goes on in a Voliére on a cold winter day), you can have a glimpse here.I finally found a trial version link for the Nik 4 collection and downloaded it to try it out. Now, both functions are standard of today’s raw converters, even Affinity Photo has a vignetting slider, so it makes DxO look a bit very greedy - or needy, depending.Īnd please don’t come up with all the rebates - if somebody needs it in February 2023, he will have to wait until Black Friday?Īll I’m saying is, this vignette function is very banal and should not be connected to extra costs. And I could not find a way to get the circle point elliptical, but if I had to, I’d use two control points more, align them and make the center one bigger - no one would be interested if it’s an ellipsis or a couple of control points, right? Just a bit more effort and a little bittle more workaround The movement of the ellipsis happens while I’m looking at its effect, not with a side view/jump between toolbar and tool clutter. which is way more flexible than the normal vignette command. I was not using it that often, but thanks to Wolfgang I found something new. I was a bit surprised what the points on the ellipsis can do. For me it is an essential component of PhotoLab, and goes way beyond its 100+ film emulations.īildschirmfoto um 00.08.06 3074×2464 497 KB I use a number of the tools in FilmPack 6 all the time and there are only a couple of its features like Light Leak that I don’t use. You can than add Viewpoint for another $99 if you wish, but the most important feature in Viewpoint, the Perspective tool, is now available to all users of PhotoLab 6 Elite without requiring a Viewpoint license. For example, that means that you can purchase PhotoLab 6 Elite, normally $219 USD and FilmPack 6 Elite, normally $139 USD for a total of approximately $251 USD with the discount applied. Currently, for Christmas you can buy two of them and get 30% off. Second, purchasing all three PhotoLab suite programs together has always be significantly less expensive than buying them separately. I don’t use it often, but I have used it to great effect… PhotoLab has a separate tool intended for the removal of lens related vignetting. It has several sliders and options and can add both positive and negative vignetting. It is a tool to creatively add vignetting to an image. Just a couple of points The Creative vignetting tool has nothing to with removing lens related optical flaws. And as standard I consider “what you get everywhere else as well In my eyes, standard functions have to be part of the standard package. VP and FP add more than 100% to my basket when added without rebate to the Elite version. Especially since each and every other RAW converter has a standard tool without any extra costly license? When I think about it: What has a vignette to do with “film”? It’s an optical flaw to be corrected. That sounds reasonable and I’m sure the outcome of this thread will be the successful activation of your FP license.

To use, weld your hardy tools to the head of different bolts.įill a large metal bin (or trash can) with water until almost to the top and keep a hose nearby. Tighten a bolt and nut through the overhang with the bolt on top, and weld the nut in place on the underside. It's impossible to drill a square hole, so instead drill a 'round' hardy hole measuring approximately 5/8″. Drill a hole about 5/16″ in size – this will be your anvil's pritchel hole, This will take a few rods and a lot of heat!Īfter welding, cut the end of the spring section off about 4″ from the rear (away from the horn) end of the track.Ī real anvil has two holes – a square one, called a hardy hole, and a round one, known as the pritchel hole. Because of the curve, the rest of the spring will be higher than the top of the track.įlatten the spring section to the top of the track using clamps. Spot weld it in several places, then remove your clamps and weld the two pieces together. Once your spring section is cool enough to handle, weld the square, forward end to the base of the horn – the point where the triangular horn becomes the same width as the rest of the track. This annealing process will remove the stress from the molecules of steel, allowing it to be easily bent and not spring back. Remove the temper from the steel to make it flat and stay that way – this process is called annealing. The simplest way to do it is to cook it in a forge until it gets red hot (literally), then take it from the heat and bury it in a big pile of ashes. This is where the section of truck leaf spring comes in. Make a flat surface on the top of the anvil. A torch would be most ideal – it is easy to manipulate and saves a lot of time. Soften the metal with fire for easy cutting and shaping. Shape the railroad track roughly into an anvil shape.īasically, an anvil shape amounts to a horn on one end and a square on the other end.

Looking ahead, the group hopes to expand this platform into practical electrocatalysis by using Pt-HEA-nanoparticles that seek to increase electrochemical surface areas. The platform is applicable not only to electrocatalysis but also in various fields of functional nanomaterials." It is valid for clarifying the precise correlations among the atomic-level, surface microstructure and electrocatalytic properties of HEAs of any constituent elements and ratios and, thus, would provide reliable training datasets for materials informatics. "Our newly constructed experimental study platform provides us with a powerful tool to elucidate the detailed relationship between multi-component alloy surface microstructures and their catalytic properties. The equality holds for reversible processes, the inequality for irreversible ones. Wadayama and his group stress the wide applicability of their findings, both for any constituent elements and to other nanomaterials. The entropy S is that state function (discussed by Clausius as early as 1854, but not given a name by him until 1865) whose differential is given by the equation (3) d S Q / T, where T is the absolute temperature. This indicates that the atomic arrangement and distribution of elements near the surface, which creates a 'pseudo-core-shell-like structure,' contributes to the excellent catalytic properties of Pt-HEAs. They discovered that the Pt-HEAs' surfaces performed better in ORR compared to surfaces made of a platinum-cobalt alloy. Using advanced imaging techniques, the group examined the atomic-level structure of the Pt-HEAs' surfaces and studied their ORR properties. "This produced a model surface for studying a specific reaction called the oxygen reduction reaction (ORR)." "In our study we made thin layers of an alloy called a Cantor alloy, which contains a mix of elements (Cr-Mn-Fe-Co-Ni), on platinum (Pt) substrates," explains Toshimasa Wadayama, co-author of the paper and a professor at Tohoku University's Graduate School of Environmental Studies. Their breakthrough was reported in the journal Nature Communications on July 26, 2023. Now, a collaborative research team has created a new experimental platform that enables the control of the atomic-level structure of HEAs' surfaces and the ability to test their catalytic properties. Hence why researchers are seeking to understand the correlation between the atomic arrangement and the catalytic properties exhibited by HEAs. But unravelling this complexity is crucial, since the surface properties of materials often dictate their catalytic activity. Because they are made up of differing constituent elements, HEAs' atomic-level surface designs can be complex. |
