Both are used to show and hide different parts of the layer, but the way they go about it is completely different. I know it sounds crazy, but now that we've added our layer mask, click once again on that exact same Layer Mask icon:Ī "vector mask" thumbnail appears to the right of the layer mask thumbnail.īoth the layer mask thumbnail on the left and the vector mask thumbnail on the right look exactly the same, but there's a big difference between a layer mask and a vector mask. It never occurs to them that maybe, just maybe, if they were to click on that exact same icon a second time, well, there's at least a slim chance that something else might happen! And it's too bad for them because in this case, something else will happen! Those people click on an icon once, see what it does, and then take a nap. ![]() We're going to see something that many people never see. Okay, so if we're not going to be using the layer mask, why did we just add it? Well, we're about to do something that many people never do. We won't be covering layer masks in this tutorial since we won't be using them, but if you want to learn more about layer masks, be sure to check out our full Understanding Layer Masks tutorial in our Photoshop Basics section. Here's the image I'll be using for this Photoshop tutorial:Īfter clicking on the "Layer Mask" icon, a layer mask thumbnail appears on "Layer 1". Rounded corners, we have complete control over just how rounded they are! The answer? Very easily, especially when we use a vector mask! In fact, not only can we give the photo That may be fine if we're simply getting the photos printed, but what if we want to use the photo in a design or a collage? How do we convert those sharp corners into round ones? It's a bit unfortunate then that every time we take a photo, even if it's a photo of a kid's birthday party with balloons and party hats, the photo still ends up with sharp corners. Okay, so that may be exaggerating things a bit, but rounded corners definitely look more appealing to us than sharp right angles. You can take a square or a rectangle with its harsh, right-angled corners, which normally doesn't seem very fun to us at all, give it rounded corners instead, and suddenly it will seem like the life of the party! In fact, it doesn't even have to be a complete circle. They're the "warm, friendly and fun" shapes. Chances are, unless you're the type of person who enjoys spending Saturday nights reorganizing your filing cabinet (not that there's anything wrong with that), you'll pick the circle. Just grab a pencil and a piece of paper, draw yourself a square, then a circle, and ask yourself which one seems more appealing to you. You don't need to be a design expert though to experience this for yourself. Some shapes appear warm, friendly and fun, while others seem cold, rigid, more serious. Different shapes have different effects on us. ![]() As with most things in Photoshop, there's about 17 different ways to create rounded corners, but we're going to make things interesting by looking at a way to do it using something in Photoshop that many people don't even know about - vector masks! What's a vector mask? Well, if you think layer masks are fun (you do think layer masks are fun, right?), you're going to love vector masks!Īny graphic designer knows that one of the ways to get people feeling a certain way when they look at a design is through the use of shapes. In this Photoshop tutorial, we're going to look at how easy it is to create rounded photo corners. ![]() Currently (not unlike other programs) you have to know how to navigate the root folder to add/subtract additional plugins. They can also improve the plugin installation process. I haven't been able to upgrade to the newer version because my machine isn't updatable past Catalina. It still runs better than most mid-to-high level Windows PCs. I currently run Catalina, because my Mac was future-proofed seven years ago. ![]() Support varies, with some apps including 360-compatible titles, stabilization, and motion tracking. It is industry-level technology with a plug-and-play design. Other options are Adobe Premiere, Apple Final Cut Pro, and Magix Movie Edit Pro. Unlike Adobe Premiere, there are no ridiculously complex processes to learn before being able to operate the software. The software can be used as lightly or as heavily as needed for any job. With that said, a complete novice could spend five minutes with Final Cut Pro and develop enough knowledge to put together elementary level edits. After 7+ years, I'd consider myself a higher level user. I use it daily to create productions for brands, ad agencies and content creators. The ease of use for multiple levels of difficulty. That's how much I enjoy using Final Cut Pro. I learned enough about Adobe to use AfterEffects and then integrate it into Final Cut Pro. It's also beneficial to learn so you can integrate other programs, such as AfterEffects. Adobe Premiere is fine if you want to learn the Adobe ecosystem. I didn't hate it, but it seemed unnecessarily complicated. Track moving objects in clips to match their movement with an effect, graphic, or. Create studio-quality 2D and 3D titles and set them in motion, without leaving Final Cut Pro. Reduce or eliminate grain and video noise with easy-to-use noise-reduction tools. When I first started editing video, I tried Adobe Premiere. Retime clips to create cinematic fast-motion, slow-motion, and variable-speed effects. Final Cut Pro is the canvas that allows us to create these works. Though it can be challenging to use, it is also a great choice for enthusiastic amateurs and social. ![]() We make video content for ads, blogs and industry leading operations - everything from social media ads and recipe videos all the way to funnel oriented sales videos and B2B conference reels.

The Final Cut Pro X free trial lasts 30 days, but is currently extended to a whole 90 days due to the covid-19 pandemic, which is longer than any other free trial video software we can find. However, we’re also aware that for those that can, creators can generate their own titles and motion graphics using Apple Motion - but we’re aware that’s an extra purchase, and new skill to learn that is just one step too far for some users. We’d like to see this improved in a similar way that Adobe have done with Premiere Pro 2020 by introducing their stocks tab right inside the software. However, the Titles and Generators sidebar includes graphics that look like they’re straight out of the 90s with cheesy text and visuals. It has a good level of manual adjustment for color grading and tone details. It makes good use of space, with a clean, smart layout including the inspector panels which can switch between video, color, audio, or analyse EXIF data. Video rendering is almost instant in Final Cut Pro X, and you can scrub through clips in the browser, or timeline without lag and it even outputs audio simultaneously. The GUI is relatively intuitive, but certainly baffles beginners at times with hidden menu items behind drop-down windows. Final Cut Pro X: should you buy it?įinal Cut Pro X is ideal for professionals that require the extra level of high-end control that other softwares lack (such as the massive multicam feature) and also caters for less experienced users, too. Where Compressor adds customisable output settings which also supports 360° video, HDR, HEVC and MXF output. Motion is capable of processing 2D and 3D titles, transitions, and real-time effects, as well as being capable of processing this all in 360 degree content as well. For an additional $50 you can also integrate Apple’s Motion, and Compressor softwares into FCP X for improved motion graphics and content delivery, with which FCP X shares its render engine. ![]() Editor" button, then the sample loads in my editing app, I do a tweak or two, then hit "Save," which replaces the old sample file with the new fixed one.

I'm thinking DP at 149 for the upgrade is a better choice than Peak or DSP Quattro. Sounds good to me!īut unless I'm mistaken, ProTools wouldn't be the best option for this, because when I hit "Save" in ProTools, it saves the session, but not a tweaked version of the audio file. Click the "Ext Editor" button, edit the sample in whatever audio app, then save it, and the old sample is replaced with the fixed one. That little "External Editor" button seems perfect for these minor little fixes. Maybe there's a click I can fix with a pencil tool, or maybe the volume curve could use re-drawing, or whatever. RX9 by iZotope is REALLY powerful for all sorts of things like getting rid of pops/cracks, de-reverbing, isolating vocals & way more. used to use audacity as a DAW before i used ableton, so not sure about its potential as an audio editor. even the stock plugins in ableton are super powerful. But sometimes I find that one or two of the samples have minor errors. depends on what youre trying to do when 'editing audio'. I do all my initial sample editing in ProTools, then I drag them into Kontakt. ![]() Then stir in sour cream, plus 2 tablespoons of chopped cilantro. Cook until thickened, about 8 to 10 minutes. Once this mixture is smoothed out, bring the vegetable mixture into the milk mixture, and then add the reserved beef. Then slowly add the milk while you whisk and scrape the bottom of the skillet. Add soy sauce, Tabasco, and Worcestershire to the gravy side of the skillet. Cook for a minute or two, until the mixture is browned and fragrant. The mixture will be thick and paste-like. Draw in as much butter, beef fat, and juices from the vegetables as you can, into the flour. When the butter is melted, sprinkle the flour over the butter, whisking all the while (a flat whisk works awesome here!). Add remaining 4 tablespoons of butter to empty side of skillet. Tilt the skillet to draw the juices from the vegetables out into the empty side of the skillet. Now slide everything in the skillet to one side. Cook until the onions are transparent and the mushrooms are nicely softened, about 10 to 12 minutes. Once butter is melted, add the onion, red bell pepper, poblano pepper, mushrooms, jalapeño pepper, and garlic. Discard all but 2 tablespoons of the beef fat, and then add 2 tablespoons of butter to the beef fat in the pan. Remove browned beef to a plate with a slotted spoon. Add beef and brown it, stirring occasionally. Heat a large cast iron skillet (mine is 12 inches in diameter, with tall sides) over medium to medium-high heat.

If you’re one of those people who likes to bypass makeup tools to use your hands, you may want to skip this product - surprisingly, the formula doesn’t melt into skin as nicely when using your fingers.įormula: Vegan, Cream | Size: 0.37 oz | Shades: 6 | Finish: Matte When used together, the contour and brush beautifully sculpt your features. Though the formula blends like a dream, we especially love that the product is essentially a two in one: You’ll find a gorgeous matte cream on one end, and a built-in buffer brush on the other. Though it blends like a dream when using a brush, it doesn’t blend as seamlessly when using your fingers.Īlthough celebrity makeup artist Mario Dedivanovic obviously didn’t invent contouring, he’s been dubbed the ‘contour king.’ (He’s the mastermind behind Kim Kardashian’s signature sculpted look.) So it came as no surprise that when he launched his eponymous makeup line a contour stick was included - and frankly, it's incredible. To avoid this, stick with two to three swipes for a dramatic, comfortable contour.įormula: Cream-to-powder | Size: 0.25 oz | Shades: 9 | Finish: Matte If you’re looking for a more dramatic sculpt, you can build up the intensity with a few more swipes, but know that building the product can sometimes result in a drying effect as the day wears on. New York-based makeup artist Toni Greenwood explains that the geometric packaging makes the stick easier to grip and allows anyone to seamlessly glide the product across the hollows of their cheekbones, along the jawline, and down the sides of the nose without issues.Īccording to Los Angeles-based makeup artist Rachel OCool, the rich cool-tones and matte finish of all nine shades also make these fantastic for creating the most natural shadows on your face. The weightless, longwear formula creates the perfect sculpt every time, but the smart design goes beyond the easy to blend formula.

Plus, they’re creamy, portable, and buildable, and require less tools than a powder. For years I thought contouring was a makeup technique best left to the pros, but really all it takes is a good contour stick to achieve the sculpted cheekbones and sharp jawline of my dreams.Ĭontour sticks give everyone - from makeup novices to pros - the control and ability to expertly diffuse facial shadows and create model-esque definition. ![]() It may seem like everyone on social media naturally has the most defined cheekbones imaginable, but I’ve uncovered their secret - contouring. ![]() Things went breezy for the couple, and they finally made a red carpet appearance together when attending the 64th Grammys in Las Vegas.

When it powers on, I get: solid green, solid amber, flashing amber. I went to best buy to get a USB3.0 to Ethernet to try and connect the Airport to my Macbook and reset it that way, but I see nothing when connected on the Wi-Fi/Network menu or in Airport utility. I understand I can just reset all of them to defaults but I can’t reset this problematic one… After I was out of ideas, I returned it to its usual spot, and now the entire chain of Airports are all out of wack and won’t reorder as they usually do.

If you want to find out how C (and C++) handles integer overflow, you have to take a look at chapter 6.7.5 “Types”, the following sentence in particular: Other possibilities exist, ranging from saturation (the overflowing value is set to the largest/smallest value and stays there), to raising an exception, to doing whatever an implementation fancies. Wrap-around is, however, only one way to handle integer overflow. If you add one to the largest value, you arrive at the smallest if you subtract one from the smallest value, you get the largest. Wrap-around denotes that an integer type behaves like a circle that is, it has no beginning and no end. One possibility is what is conventionally referred to as wrap-around. Now that we know what overflow is, we can tackle the question what happens on overflow. And so shall I, for the rest of this discussion. It’s common among programmers to use the term overflow for both, overrun and underrun of a type’s value range. And, see you in the following articles.Īgain, you can find all related source code at □. We hope you have learned something interesting. In this article, you have discovered the integer overflow vulnerability in the smart contract, how an attacker exploits it, and the solutions to fix the issue. Please refer to this link for the latest OpenZeppelin’s SafeMath library. The library used in the code is just a simplified version for brevity’s sake. The contract applies the SafeMath library to prevent any underflow or overflow issues in lines 46, 50, 56, and 58. The FixedMoonToken contract above is the fixed version of the InsecureMoonToken. Therefore, you can buy or sell 1, 2, 3, or 46 tokens but not 33.5.Įxactly, the InsecureMoonToken contract is vulnerable to integer overflow. In other words, 1 MOON token will always have a fixed value of 1 Ether. The MOON is a non-divisible token (token decimals = 0) pegged with 1 Ether. The following presents the InsecureMoonToken contract that allows a user to buy or sell MOON tokens. Nonetheless, feel free to contact Valix Consulting for your smart contract consulting and auditing services. Hence, do not use the source code in this article in your production. Some contracts are vulnerable, some are simplified for minimal, some contain malicious code. The smart contracts in this article are used to demonstrate vulnerability issues only. You can find all related source code at □. This article will explore how the integer overflow happens and how to prevent it when developing your smart contracts. Integer overflow might be one of the most commonly known issues in the smart contract security field.
