The Rigol DS1052E

Simon:
Thanks Trent, normally the lowest possible setting on a camera is plenty for web purposes or there are some nice freeware photo editors out there if you like fine tuning or have like me a minimum of 2 Mp on your camera, although thats not too bad, paint.net is quite a good one, I always shoot at 10 Mp and then worry about it later as my job is as a QC inspector so often I have to photograph damaged goods, on later inspection we may find more damage but with a large image an area can easily be isolated and croped to a suitable size.

TrentO:
Simon, thanks for the advice--that's a 'tip' that I can actually use. Dago's tip is a useful as well.

EEVblog:
You usually don't need to lower the res much, the key is the compression ratio.
I use Irfanview, and simply re-saving images with 70-80% JPEG compression with the same res saves a lot of space for starters.

Simon:
dave a 6 Mp image with with 66-70 % compression will still be large I find the best thing is a 800 pixel wide image with a good 80-90 % compression, this is immediately usable on the web is not large (1-200 KB) and is of good quality and easier to handle in up/download

markus:
Two questions:

1) What do we think of the Rigol vs Owon o-scope, say 5022S?  Apart from 25 vs 50mhz.

2) Do we think it is possible some people are receiving counterfeit/copied Rigol scopes, explaining the quality differences we are seeing?  This seems to be a problem with Chinese goods..

Dave, do you know the vendor you purchased your unit from on ebay?  Could other buyers also list their vendor?

Thanks for the video blog, I enjoy it!

I also agree with others that suggest an episode about general scope use, tips, tricks, etc.  I would like to see that. :)
