i noticed! thanks

comment Why do these images taken at significantly different ISO appear equal in quality?
jrista, i appreciate your willingness to help. the question i was asking was caused by my initial thoughts that lower ISO should not only decrease the amount of noise, but also improve image quality including things like quality of colors. basically i was looking for a more visible difference between 160 and 1600. but i get it now that the iso range is much larger and the difference is narrowing in newer cameras (mine being brand new). i also learned about "exposure time noise".. very helpful.. i'll make another comparison on more even grounds.

thank you sir. "exposure time noise" was a concept i was not aware of.

interesting, so you are saying that the longer the exposure is, (the smaller the aperture) the more noise gets in?

@mattdm, i only resorted to tinypic, after this site rejected my photos with that warning. the photos i was uploading here were straight from the camera w/out any modifications

mattdm, thanks for editing! do you know why i was getting that error when i tried to upload my images here? something about framing not allowed? these were images straight out of the camera..

thanks, i went back and looked at zoomed in versions. that finally revealed a more clear difference in the graininess.

there was a tripod, no glass, also in one shot a car went by which is why you see the some reflection in lower left corner... i'd like to hear more about why you state that the camera settings were counter intuitive? at first i shot with low ISO to get best wall detail.. following that, i increased it to decrease apperture, and capture subjects crossing in front of the wall

thanks Russel. i did realize that aperture difference does not help a direct comparison (did not think of it at the time of shooting). Does depth of field matter that much when shooting an object that is equal distance all throughout the photo (such as a wall) ? also, why f/11 and not f/5.6 ?

yes, i am no hardware guru, but actually image quality and low noise at high ISO were major selling points in this camera for me. The reason for the question above is just me trying to understand the sensor, and exactly what to expect at different settings. thanks for taking the time to answer

jrista, good point. i just felt a little bit silly that i posted my question before actually zooming to 100%, because at that level the difference was apparent. so i thought my question was not that good which is why accepted so quickly.

actually those were "fine" jpegs. i thought it was raw, but it was dark and i set it incorrectly. would raw make much difference in respect of iso noise??

after zooming, even the lit areas are grainy at 1600

you're right.. i zoomed in to 100%, and focused on upper area. i get it now :)

ok, but do you see any difference between those 2 shots ?

comment How can I make the sky in this photo more vibrant?
yep.. after much more experimenting , the white balance is absolutely the key factor here. thanks

comment How to check what White Balance setting was used (on a Mac)?
wow! that tab even shows me which of the 39 focus points was used!
