800 USD ATLAS Photo Studio
Web Programming
ATLAS is a landing page for small businesses in Romania, created with the aim of expanding the customer base and serving as a digital business card for the owner. The main goal of the project was to create a minimalist yet bright and memorable design with all the necessary functionality: a quick way to contact the owner via phone, WhatsApp, Instagram, or Telegram, as well as the ability to place an order. The website is multilingual and targeted at residents of Romania who speak not only Romanian but also English, Russian, and Ukrainian. To make the site more dynamic and visually appealing, 3D graphics were used — allowing users to not just view locations as static 2D images but to immerse themselves in the space and explore the shooting location in advance. For user convenience, Google Maps was integrated, and the exact geolocation of the studio was set up. The website is fully responsive for all types of screens, including mobile phones, tablets, and desktop computers. The content and elements dynamically adjust to the screen resolution, providing a cohesive and tidy appearance on every device.
