K20D: Relationships among Pixel Density, Sensor, Lens

The K20D cannot out resolve all lenses although it can out resolve some lenses. When you shoot in RAW you only get 1 size 14.6. Shooting in RAW to get maximum resolution is not the only reason to shoot RAW and probably not the best reason to shoot RAW. What determines what resolution you need is what size you print/view the photo. If you use the max size best JPG quality you can get you will have about the same resolution as RAW but not only do you not get the control you get with RAW to make adjustments but you will probably have more resolution then you need for most printing, assuming you are not printing for max size. If you go for the smaller size JPG you will probably not out resolve most decent lenses and be good to print to somewhere around 8/10 depending on how picky you are. You do loose the RAW control but you save space and all you are doing is have the camera PP for you from RAW then throwing the RAW away. This is not changing the sensor size so you are not gaining any thing there just throwing a lot away.

I use RAW so that I have the most control later. When I PP either in camera or on my computer I can then adjust accordingly to get the resolution I want/need. If I have more noise then I want and have more resolution then I need I can trade off some resolution by using noise reduction. This is one of those things that works better with RAW. If you donít need or want the other thing RAW can give you then just use the smaller size JPG in the camera. Just remember that this is a tattooing event. You cannot get the photo to be as good as you could get if you had used RAW.

I rarely consider the size of files regarding storage. This is one of the cheaper parts of this hobby. I do consider the size of the file for transport (i.e. E-mail) and the print/view size that it is going to be used for but I do that in PP.
