Creating Tree Shadows in Photoshop Perspectives

While modeling programs like SketchUp and renderers like Lumion can create trees and tree shadows, there are times where it can be helpful to insert trees and shadows using Photoshop. This video demonstrates a technique for inserting trees and creating tree shadows in Photoshop perspectives. This process uses photographs of trees in place of modeled…

Inserting Grass in Photoshop Perspectives

Outside of advanced materials and external renderers like Lumion, it can be difficult to represent realistic grass in perspective renderings. Often it will simply appear as an image of grass on a flat surface. This video tutorial will discuss replacing this approach to grass with a photograph to create a more realistic representation of grass…

Using Gridded Soils in GIS

This video walks through the steps for using gridded soil data from the USDA NRCS Geospatial Data Gateway.  The video will describe how to download and extract the data and use the join tool to merge soil characteristics into the 10 meter raster file to then map the data by soil characteristics. The video will…
