| Another great noob question. My friend asked me if I had a lens that could take 16:9 aspect ratio shots. I didn't know what he was talking about. He said so that he could use some of my shots as wallpaper. So is there a way to set aspect ratio or is it just how you crop the picture yourself? |

The aspect ratio or ratio of width to height of the image is determined by the sensor so in your case it would be how you crop the picture.
EDIT: Just ask him what resolution he's running and crop to that pixel dimension.

16:9 is the aspect ratio of computer monitors. If your image out of the camera is not that ratio, you can certainly crop it to that ratio.
However mine is 4:3 out of the camera and by stretching the pic slightly when you set it as the wallpaper, it looks very close to perfect. All you do is specify Position = "Stretch" when you pick the image for wallpaper. |

The D80 shoots 3:2 aspect ratio. |

When I set aspect ratio on Photoshop at 6 x 4 and use the square marque tool it shows that my camera shoots at that ration. So I dont need to crop to print a 6x4 photo. If I want to print and 8 x 10 I have to crop the longest side. You still need to alter image size and or resolution to suit need. 6 x 4 would then be the same as 2 x 3.

Only if you have a wide screen monitor and even then some are 16:10. |

| I think nikon dslr shots come out 3:2. At the very least I know canon does. |

You can also use your square marque tool, click on fixed aspect ration and type you 16 and 9 in appropiate boxes and then use your marque to mark that ratio. I then use my crop tool to crop that and you can move your cropping to suit your picture so that you crop out the areas that you dont need and keep the important parts of the picture.
I use this all of the time when getting portrait photos printed so that the lab doesn't allow their machines to randomly crop to the ratio, you know missing heads etc. |

The majority of widescreen computer monitors aren't actually 16:9.
Most popular widescreen resolutions (for example 1680x1050, 1920x1200, 1280x800) are 16:10.
Non-widescreen monitors have historically been 4:3, although nowadays a lot of LCDs run at 1280x1024 which is 5:4.
As TechnoShroom says, best is to find out what resolution wallpaper you need and scale to that, although of course it helps to know the ratio so you can crop beforehand. Don't forget you can use the canvas size tool to add a border if your shot won't crop naturally to the right ratio.

If you want to have your image fit his desktop perfectly (without the OS resizing it and introducing imperfections) you should ask him what his TOTAL RESOLUTION is, i.e. 1680x1050, 1920x1200, 1280x800.
Resize your image to this size. You may need to crop to the correct aspect first, but ultimately it's the pixels that matter. |
