TapGlance has several levels of quality and resolutions of renders, to better match your needs and budget. The quality levels are Preview, Standard and Photo-real:
Preview quality is the fastest and cheapest way to verify that your scene is correctly set up. We strongly recommend a preview render before each standard or photo-real one. Preview render is locked to 640 by 480 pixel resolution and will usually be somewhat grainy.
Standard quality produces a good balance between quality and time. In many cases standard quality render will produce excellent results that appropriately represent your scene.
Photo-real quality produces the most life-like results. It is the only mode that takes into account any artificial lights present in the scene, like lamps. It also lets you produce night-time renders by enabling the “Simulate Night” mode.
