Island at Night

The view is beautiful indeed and very neat. This picture is taken somewhere in the beach where the opposite side has different night lights which created the colorful picturesque of the place. Plus the factor of the camera used optimize the result. Nature is also beautiful at night not just in the day. More of the photos to come in the coming days. Stay tuned in my blog.

The ISO setting (taken from the greek word "iso" which means equal) is an artificial spin-off of film photography when it used to be an indicator of just how much AgBr (Silver Bromide, the yellow compound that turns black upon exposure to light) has been incorporated into the film. The higher the ISO, the more AgBr, the more sensitive to light. With today's digital cameras, the ISO setting has been retained. But this time, instead of a chemical emulsion, the rating is a measure of the degree of sensitivity of the light sensors. So, if you're taking a picture of a darkly lit subject, you increase the ISO setting. But in so doing, specks of non-existent pixels will emerge in your finished product. Hence, the grainy (film) or pixelated (digital) appearance. (Word of advice: always use the lowest possible ISO rating for best results.)
