Software tutorials for Adobe Photoshop and Microsoft Excel

Various technical tutorials provide guidance on utilizing software for specialized tasks.

One guide explains how to create large-format XXL posters using Adobe Photoshop. Users can distribute a single image across multiple DIN A4 sheets by using Photoshop's preparation tools and the tiling function found in many printer drivers. For a DIN A2 format, a resolution of 150 to 200 dpi is often sufficient, and an image with approximately five megapixels can provide adequate quality for viewing from a normal distance.

A separate tutorial demonstrates how to use Microsoft Excel VBA macros to open and display image files such as JPG, PNG, or BMP. By using the FollowHyperlink method, Excel can pass a file path to the default Windows image viewer. The guide includes instructions on adding error handling to check if a file exists before attempting to open it, which prevents runtime errors.
