Great mcmtanyel 2016-11-27 19:16

Hello Ike,
This is a good vantage point that lines up the flags of the nations with the legs of the chair. Well seen and rendered.
Regards,

PS. I know, you don't recommend using high ISO but I am lazy and do not carry a tripod. I do not mind the noise introduced from high ISO but I do mind the motion blur that lower ISO setting would introduce. To me, it's a compromise between shake-blur and noise and I choose the lesser of the two evils.

Exclamation To mcmtanyel: Tripod, ISO and motion-blur

Hello Murat,
Ususally I do not carry a tripod, especially when I travel abroad.
There is no relevance between ISO number and motion-blur.
The ISO number simply mean how much light the sensor absorbs - a high ISO number would not prevent camera shake or fast moving object. When I take airplanes pic.'s always use ISO100 !!
No more than that, otherwise the sky would look jugged.
Try and see.
Ike

Read this, especially section #3: about ISO.

There is an indirect relation between ISO and shake-blur. High ISO is selected usually under low light conditions in which the aperture opening is already at maximum. In this case, decreasing ISO will result in decreased shutter speed. That means longer exposure time during which your hand has more of a chance to shake or move.
Thanks for the link, it's a good read, but even there (in section 4) the author admits that low light conditions where flash is not allowed might require high ISO. I don't use flash, except for fill in, so this is the compromise I've come to.
Another factor is that most of my photos are taken on trips where I do not have the luxury of time to experiment with different exposure settings, so I click once and try to catch up with Mary.
