Take your photo, crop it to 800 x ###(160-800) and then edit as appropriate.
Advanced editing.

| No thank you. I really don't want to see a lot of very low quality images. |

Cropping does not lower the resolution/quality -- but I'm not sure of the point of simply including a lot of extra data around your composition which you'll later crop away.
What makes more sense to me is a "no cropping allowed" challenge, where you can use all of the Advanced editing tools except for cropping -- you must compose your image exactly as you want it within the full frame (noting that some cameras have the ability to shoot natively in 3:2 or 16:9 aspect ratios in addition to the most common 4:3). |

Yeah General, I like the idea of a no cropping challenge much better.
You certainly will end up with a much lower quality photo if you crop it to 800px. Give it a try. Crop one of your photos to 800px wide, upload it to DPC, and see what it looks like. I can pretty much guarantee the quality is going to suffer massively.
I did just that, and this is what I get from a very sharp original image. The crop was over the focus point of the image. I did apply sharpening like I do for all entries (after I resize them).
It's not terrible, but you can see that it's not very good either.

| You must be cropping and resampling at the same time -- cropping alone preserves the selected pixels exactly as recorded on the card. Cropping to 800x600 pixels should yield the same result as setting the rectangular-selection tool to 800x600 pixels and then selecting "Crop" from the Image menu (Photoshop terminology). The remaining pixels are unchanged from the original capture. |

PIxels unchanged, yes. But that is the problem. Unless you have the most sharpest of glass ever produced, and a giant sensor, and no anti-aliasing filters, and perfect focus, then you will see 100% crop that is much softer than what you see the downscaled full resolution photo to be.
Where's kirbic when you need someone to explain how it all works :) |

i like the challenge idea. i have an edge on this. many of my pictures are already a 100% crap.

Not true. It depends on the camera.

A "downscaled full-resolution photo" is a contradiction in terms -- it's either at the native resolution of the camera's sensor or it has been resampled (either up or down).
Nowhere in this challenge suggestion does it say you couldn't apply sharpening to those pixels, just like you need to after reducing (resampling) a picture to a DPC-entry size.
To claim that a resampled image is any sharper or better-detailed than the original frame is completely counter-intuitive to me ...

Totally agree. Don't like the challenge idea at all. |

Maybe if the OP could expand on what the purpose of such a crop would be...?
Otherwise, pass. |
