The discussion revolves around finding a high-resolution background image for an A1 research poster focused on molecular spectra. The original poster creator struggles to find suitable images, noting that actual photos of molecules are not available due to current technological limitations. They initially searched Google Images and DeviantArt but found the resolutions insufficient. A participant offers to create a custom 3D rendering of a molecule using 3ds Max, asking for specific details like colors and resolution. The poster creator expresses excitement about this offer and requests modifications to the design for better visibility on the poster. The conversation highlights the collaborative effort to produce a visually appealing and scientifically relevant image while acknowledging the challenges of sourcing high-quality molecular images. The use of 3D rendering software is emphasized as a practical solution for creating the desired visuals.
