Decided to try out aperture priority mode after shooting Auto for a few days. On a D5100 with 18-55 kit lens. Tried taking stuff in my room on 18mm with f/8 and f/22. The shutter time is really long, 3-4 secs and it results in really out of focus pictures. ISO is at 100. However, taking a landscape picture at 18mm and f/22, the shutter is almost instant and produces pretty clear images. I am sure I am missing out on some settings that I need to adjust but I cant figure out which it is. :dunno:
Aperture Priority mode and extremely long shutter times
- Thread starter SacredSoul

For picture taken in your room, "out of focus " pictures may be from the hand shake arising from long shutter speed. Try repeating same test using a tripod or place camera on table surface, instead of hand holding, when taking pictures inside the room. This is evident from your second information which says "shutter is almost instant and produces pretty clear images".

TS, you are missing out a lot of things... tell you want, set your ISO to 800 and above, and set your aperture to the widest that you lens can offer -say 3.5 and see if you can make out what you have been missing. And before I forget to say, check your shutter speed to note the difference.
Shutter speed at 3-4 secs handheld will of course result in blur shots :sweat:
The lighting conditions of any situation will determine how fast your shutter speed can be at a given aperture at a certain ISO. I'm certain your room's lighting is very different from the lighting where you shot your landscape shots.
Learn how to balance the shutter speed (that you can safely handhold your camera at) with the aperture and ISO and you should see the difference.

Thanks for all the replies! Yes, with the higher ISO setting, shutter speed is alot quick producing clear images. One more question, for landscape shots, with high f-stop values, images turn out to be dark. Higher ISO values will fix this I presume?
For landscape shots, try to keep your aperture within f/8 and below. Regarding ISO, try to keep to 800 and below and you should be fine.
Guides are made for a reason.

Basically, attempting to squeeze an equal amount of light via a smaller hole will cause the light rays to diffract, causing images to be less sharp compared to a bigger hole (smaller aperture) where light rays diffract less.
Here's a link for you to read: Diffraction: When Smaller Apertures No Longer Mean Sharper Pictures - Photo Tips @ Earthbound Light
Look at the sharpness between the f/8 and f/22 comparison.
Hope this helps.
For street photography, different people have different preferences, some prefer using apertures from f/5.6 ~ f/8 so everything they want is sharp.
For others, they would rather use apertures like f/2 ~ f/3.5 in order to isolate their subjects from the background.
It's all about personal preference. But using larger (or smaller, if you will.) apertures like f/2 ~ f/3.5 will allow you to have a faster shutter speed, which will be helpful in most cases.

f11/12 - die die upper limit
above that - accelerating degrading
with your short FL, there is no need,... f5.6 is more than enough to get everything in focus....with a little attention
the f/22 recommendations is from those books referencing from film days (or lower pixel density fx), which were not updated!

Thanks again for the replies. Have a much better understanding of aperture/shutter speed and ISO now. Thanks again!
Play around with your settings and things will be clearer rather than reading from sources. Put them into practise and you will get more out of your camera. Hehehe we should shoot together. if you don't mind me as newbie. Hahaha have fun shooting

I got my first dslr 5 days ago. Think I more of a noob lol. And sure, we can shoot together!
Read through some of the comments in this thread... and had to input this...
It is NOT correct to say that for landscape it would be better to stay at f8 and below... and although there are lots of theory behind the light deffraction and stuff like that. But one had to take into consideration of many things before applying that theory... and it all boils down also to individual's lenses and camera... next... do not forget the DOF... if a lens was to use a big aperture and the DOF is too thin, parts of your landscape will not be sharp or at least in focus.
So many of the landscape photographer actually use an aperture smaller than f8.

It really depends on a lot of factors.
Actually diffraction limit can be calculated... see here: Diffraction Limited Photography: Pixel Size, Aperture and Airy Disks
