Breaking things is part of making things stronger,” says study senior author Yinzhi Cao, a cybersecurity researcher at Johns Hopkins. “Our group is generally interested in breaking things. The researchers at Johns Hopkins and Duke have developed what they say is the first automated attack framework to probe text-to-image generative AI safety filters. Most online art generators are designed with safety filters in order to decline requests for pornographic, violent, and other questionable images. Large language models are essentially supercharged versions of the autocomplete feature that smartphones have used for years in order to predict the rest of a word a person is typing. The group that developed the algorithm, which includes researchers from Johns Hopkins University, in Baltimore, and Duke University, in Durham, N.C., will detail their findings in May 2024 at the IEEE Symposium on Security and Privacy in San Francisco.ĪI art generators often rely on large language models, the same kind of systems powering AI chatbots such as ChatGPT. A new algorithm generates these commands to skirt these AIs’ safety filters, in an effort to find ways to strengthen those safeguards in the future. Selecting a region changes the language and/or content on words can trick popular text-to-image generative AIs such as DALL-E 2 and Midjourney into producing pornographic, violent, and other questionable images. Start experimenting with Photoshop today with tutorials and guides, and you’ll be creating interesting sketches in no time. On top of that, you always have the Undo button to remove any changes you dislike. ![]() Most of the tools used and described here are nondestructive, meaning they don’t change the actual data of the tiny picture elements (pixels) of your image. Part of the joy of design is experimentation. See if you can create the look of an oil painting or watercolor instead. Adjusting these elements can emulate a drawing with a blue pen, for example. Try adding an adjustment layer with a specific color or changing the blend mode to Color instead of Normal, and see how the drawing changes to look more like a colored-pencil sketch. You can adjust the blending mode of the layers in your drawing to add in or highlight a specific color. The more you do this, the more natural the artwork will look. Use any of the drawing tools available in Photoshop to draw additional lines and rough up the drawing a bit. One way to make a sketch drawing look more natural is to add in some linework or doodles yourself. Try these additional techniques to add more depth and texture to sketch conversions. There are many ways to build your next masterpiece. There are dozens of photo effects and photo editing tools available within Photoshop, so if converting to a sketch isn’t working quite right, don’t give up. Here you get less of a sketch effect and more precision. ![]() Pen-and-ink sketches are more precise - with sharp, defined lines, deep blacks, and plenty of negative space. Convert a photograph into a chalk- or charcoal-style drawing to streamline details from the original photograph and add style with heavy, abstract line work. Pencil gives the entire piece a rough look. Replicate the look of a pencil sketch by converting a photo into something that resembles the looseness and lightness of drawing with a pencil. Here are some of the most common options for creating photos in various sketch styles: Apps like Adobe Photoshop give you a variety of choices for building an interesting sketch out of a photo, so it can be difficult to choose the one you want. ![]() So you’ve decided you want to convert a photo into a sketch - the next step is deciding what kind of sketch you want to create.
