		+	A classical usage is using an angle of 360 but with a up/right ratio of 1/2 ("up 10y" , "right 20x"). it keep the top of the picture as the zenith and the bottom of the picture as the nadir, avoiding perception issues, and giving a full 360° view.

		+	** I like it. Best of both worlds: small pictures in text that can be enlarged for the details.
		+	** I would nevertheless introduce the global view (RefImgCameraSampleScene.jpg) at the beginning of the camera section, as it might be of interest to know where the various objects are in 3D. (3 boxes & 3 spheres of different colours, two-half-infinite planes, a sphere as target and a skysphere). Do you want the code for the scene & cameras ?

	* I played around with a couple scenarios and I'm not having much luck. The size of these images seems a bit small (150x150px), so they don't even really make the grade when it comes to being useful. Maybe it's my <em>old</em> eyes. The smallest images we have are the panels in the [[Documentation:Tutorial Section 3.7#Radiosity without conventional lighting\|radiosity tutorial]] and they are 220px wide. Keep in mind the widest image we can use without overflowing the set page boundary is 680px. Oh and I guess you didn't notice that I had to rename <strong>ALL</strong> your first round images to conform to the naming convention. I did <em>not</em> rename these last ones, as somehow I think we can do just a tad better.		* I played around with a couple scenarios and I'm not having much luck.

		+	For the naming convention, I hope these new pictures are more conform. (where is the relevant text ? Did I miss it ?)
		+	(I'm also always afraid to specify an existing name)
		+	Maybe a section starting with:
		+
		+	[[image:RefImgCameraSampleScene.jpg]]
		+	the full world, with the camera inside the grids, looking at the green and white sphere.
		+
		+	Then either with caption isuing :
