Rendering figures with transparent or white background

I should know how to do this, but....

I want to render images of people or items without a scene. When I do so it looks fine in the save as image, but then when I take it into postwork it has a black background that I cannot easily remove (magic wand tool is too coarse. Has anyone any ideas how I can change the render default colour to transparent or another colour that is in contrast to my figures please? The image shows part of one effort and the problem for shading.

    You need to save it in a format that has an alpha channel...jpg does not.  So save as a png or tif. As long as you don't have a backdrop, it will then give you the transparency you want.

    Yay! That worked. Thanks......

    Mind, I still don't understand why the background is white in the rendered image and black in the jpeg, and I don't recall how to change the scene background colour either. Seems the more I learn the more I forget.

    It's white in the rendered image because what is behind it is white...most image viewers will have a native background color they show for images with transparent backgrounds (some show a checkered pattern).  What you are viewing it with shows white. 

    When it is saved as a jpg, the transparent pixels are saved as 0 0 0 (RGB)...which is black.

    Hi - im probably answering the wrong question as i know almost nothing about all this, but think i do know this one !!!!!!  :-)

    Top right box, with the environment tab selected.....drop down tab at the top - type - with either backdrop or none. Select backdrop and then click in the middle of the top drop down tab - background. Note, dont open the tabl or anything, just click in the middle of it.

    This opens a box where you can select any colour you want  :-)

    Hope that helps and sorry if you were asking something else !

    All the best

    Steve
