Bokeh is the quality of the out-of-focus part of the picture. There are many factors contributing to this and everybody has a different perception about what is pleasing to his/her eyes. What kind of bokeh meets your personal "pleasing criteria" we cannot advice. But as mentioned by others: you can increase the emphasis on the out-of-focus area by using the longest end of the focal range, the widest aperture, getting the object as close as possible to the lens and having the background as far as possible.
Neither 3.5 nor 5.6 is "focal" - please read up about the basics: Photography Notes for Newbies The sticky threads are there for a purpose. Another great link (from zoossh's guide): A Tedious Explanation of the f/stop It makes it much easier for you to learn if you use the terms in a correct way.
The numbers you have mentioned are the maximum Aperture - the maximum possible opening of the lens. The maximum varies with your kit lens, at 18mm (focal length!) the maximum aperture is f/3.5; at 55mn it is f/5.6.
Regarding the Av mode just read your manual. Those modes have a purpose. You can also use P mode and adjust the exposure, the camera will change aperture and shutter speed for you. Just watch your display.
yes.. just that you will probably be more limited.
depth of field , like i always say (and as is understood commonly).. is dependent on three things.
1) camera-subject in relation to camera-background distance. if your background is far enough from the camera, then you can and will always get bokeh easily.
2) focal length. given the same aperture setting , all other things being equal, a longer focal length will have more thrown out of focus.
3) aperture setting lor. bigger aperture , or smaller f-stop number = more bokeh.
so either, go close to subject (there are limitations).. or extend to longest focal length, or open up aperture, best is do a combination of all three, i.e. shoot at 55mm, as close to subject as possible (without distortion) and open up the aperture to widest.
So are you telling me that you can be rude to them if they are clueless?
Everyone of us need to start off somewhere, and many of us started off just like them, clueless. Think of the many who had helped you one way or another when you were newbie. Think of how you would feel if you were scoff off by the seniors back then. There are one too many rude remarks I've seen in the newbies forum. If you really want to make the forum a better place and willing to come here and help out the newbies, do it with sincerity and kindness. Do it with your heart. Point them to the right direction or resources that they need, or at least tell them how to find them.
Hi just to clarify myself.. i was playing with my camera while posting on this. the reason i ask some is because i m clueless after i am trying. for instance. when i do the scroll thing.. the F 3.6 went up... F22... etc... so i am just curious if this is consider focal. and also why issit that the shutter speed (speed to take the picture) is longer.
