- Install Agisoft Metashape and activate the demo mode for now (activating the trial license will limit you to 30 days use).
- Choose an object as your target, bearing in mind what you learned about the limitations of photogrammetry with certain surfaces and materials. Following the essential tutorial, take a good number of pictures (at least 40, preferably more) of your target object from various angles. Upload your photos in Metashape and follow the instructions for processing the data and creating a textured 3D model.
- Download this image of the wall in a Roman building in the area near Pompeii. Modify brightness and contrast on different layers, then try to make the image homogeneous enough that the flash reflection disappears.
- Download the images in this zip folder. They are all photos of the same wall. Use distorsion to straighten the image, and stitch them together, using the decorative pattern as a guideline. If you can, try to make colour and brightness homogeneous.
- Download this image of a Roman wall. Use the clone stamp tool to make all the non-ancient elements (like the neon lamp and the electric cables) disappear. If you can, try to overlay your edited image on the green machette, paying particular attention to the position of the door's aperture.
