I am not sure if this is the correct category to ask this but I have been scouring the internet trying to find the answer I am looking for, I've gotten pretty close but my exact question hasn't been answered. I shoot with a Nikon D300 and primarily use my 50mm 1.8D (since the only other lens I own is a kit 18-55mm) I am an amateur you should know so if I word this funny I apologize, i'm slowly learning! I am trying to learn how to shoot in a very shallow depth of field because the photos with the incredibly out of focus backgrounds really appeal to my eye at the moment and thats my latest endeavor. Especially those I see in magazines and fashion blogs where there is a veeeery thin line thats in focus (the model or what ever the subject matter may be) and everything in front and behind is a giant blur. I am just really interested in creating the perfect bokeh! here are examples of what I am trying to perfect exactly: http://www.flickr.com/photos/sealegssnapshots/6205219139/sizes/l/in/photostream/ http://www.flickr.com/photos/annaszczek/5295696992/sizes/l/in/photostream/ http://www.flickr.com/photos/annaszczek/5019083958/sizes/l/in/photostream/ http://www.flickr.com/photos/annaszczek/4858159367/sizes/l/in/photostream/ http://www.flickr.com/photos/coldforkphotography/5442515581/sizes/l/in/photostream/ I have of course managed to get nice bokeh, but I want to be able to do this when ever I please and not just "get lucky." I realize it has to do with Aperture and the smaller the number the bigger the lens hole that lets the light in. I also realize it has to do with the distance you are from your subject and the background too MY ISSUE, Is I am able to be in Aperture Priority mode on my camera and I am able to change the number, But I really don't see the same results as the above shared photos. I see the aperture ring on my 50mm, the '22' is the only number that is orange, but of course the numbers go from 22 down to 1.8 and I know at 1.8 the lens is fully open, I can SEE that when I am holding it in my hand and turning the dial, my problem is, is my camera won't allow me to shoot on any number BUT the 22.. I get the FEE reading, which from what I have read when I googled this is my camera and the lens aren't really communicating? plus many people said on some sites that it is doing this because it's an "older lens" but I also have read up on the 50mm and it says it is fully 100% compatible and capable of working with the D300. I am just curious if I am capable of turning the aperture ring on the actual lens itself down to a smaller number AND have the ability to shoot with it. I feel like it's possible and it's just me not being very photo-literate, and there's a 'special' mode I need to be in or maybe I need to go in my cameras menu and do something, Because I can't understand how these two perfectly compatible pieces don't fully work together. So please, if you could tell me how to get around this 'FEE' issue I would be completely ecstatic! Or if none of this matters to achieve photos like above, I would just really like an answer since google hasn't supplied one quite yet for me! Thanks!
