To return this thread to in camera processing and dispell some of the myths about JPG I am posting this.
Sorry to the foodies but I will do another later.
When I moved to digital from medium format I thought a series of tests were in order to establish the capabilities of my then new Nikon D100. I took the picture of the F2 to use for the purpose. Due to the limitations of my pc I wanted to know how good the JPG files were. The attached pictures are of the print I made then, ( nearly 4 years ago ) hence the colour fade visible.
For those not familiar with this camera, it was released in 2002 and is 6 megapixel. In camera image processing is therefore not up to todays standards. For those using D70 and D50 cameras I hope this gives you some added confidence in your kit. As for Canon users I would expect the same to apply. The image was processed through Genuine Fractals but that only smooths jaggies it cannot add detail.
You will have to excuse the glare on the print but I do not have a polorising filter to suit this lens. There is also sunlight fading to take into account, so blacks are not what they were in some areas.
If you look at the lens crop, you can see the clouds in the sky through the window. A copy of the full image is pasted top left to give an idea of what proportion of the full image, this detail occupies.
