comment What is the meaning of having 9 focus points and how to see where they are?
As far as I'm concerned the information on dpreview is incorrect, though as Imre points out they're probably referring to the maximum number of faces that can be tracked. That's clearly not the same as a camera having 9 focus points.

comment How does one get these HDR effects?
@Figaro I've added an answer which goes into detail about what I think was done to obtain these results.

yeah my first thought was this is a duplicate, but people searching for the answer to this exact question wouldn't find it otherwise!

comment How does one get these HDR effects?
I disagree - I think there is a secret to this type of shot, and that secret is processing the sky and foreground separately and merging them into one shot. Having spent a long time fiddling the settings in Photomatix and Merge To HDR I found this to be the only way to get good looking results. Because the dynamic range within either the sky or land section is not that great little DR compression has to take place which minimises artifacts. The results I got with this technique to my eyes resemble the shots posted so I'd guess that's what's going on.

comment Are small on-flash softboxes useful, or a gimmick?
There is a huge difference between a lightsphere and mini softbox and that is the softbox is highly directional. If you have nothing to bounce off the apparent size of the lit surface as seen from the subject will be the same, giving very similar results as a softbox. But if there are surfaces to bounce off you'll get a very different result as the lit area as seen from the subject will contain these surfaces as well. For this reason you can't classify the lightsphere as a small softbox!

comment Is ISO 200 still considered to be a bad choice, on digital cameras?
All you will see from that experiment is the dark current / electrical noise your camera generates. High ISO settings don't generate noise, they only reveal noise already present, noise in low light arises primarily from a lack of photons so taking photos with the lens cap on is not giving you the full picture!

comment Can I straighten and crop without RAW image and without Photoshop?
+1 This is probably the best solution as the questioner states he already has the Canon software.

comment How can I estimate the reproduction ratio of an unknown macro setup?
I don't understand your comment, however I agree with mattdm, with a smaller sensor you capture less of the ruler, but you divide that measurement by a smaller number so the magnification factor is the same regardless of sensor size.
