High quality in blender render

I’m new in lender and I’ve used only cycles from beginning. There I used to render at about 2000 passes in sampling tab… but in internal, i see nothing like that. as result, the rendered image has very low qualities. How to get a HD image?

You might be getting low quality because BI does not have a true GI system and the samples are not global, instead you set the number of shadow samples for each lamp in the lamp properties as well the amount of samples for reflections and refractions in the object properties.

To use BI and get something resembling GI, you will need to learn how to utilize concepts such as light rigs, bounce lights, and AO, the wiki manual in this case can be a good place to get started, as writing everything down in this thread can take a while.
