I am using a pentax k10d with a da-40mm lens. I am trying to capture photos of artwork on a tripod outdoors (no glass, etc).
My question is, how can I increase the amount of pixels in the image? I have been using the green mode and getting photo file dimensions of about 2500x 3800. However, I am trying to get a size more like 10,000x 12,000.
Any suggestions?
Thanks!
Is there any particular reason you need this crazy high resolution? Or may it be that the images you capture are not sharp enough and you want to compensate that with more pixels?
Before adding more pixels it might be a good idea to optimize the workflow for best image quality.
- Take the camera out of the green mode, as camera might not choose optimal settings for a critical job like this.
- Make sure you use exposure settings optimized for highest resolution Aperture f/5.6 - f/8 is probably best aperture for highest resolution on DA40.
- Make sure the camera is not moving during capture by using mirror up fuction (2 sec timer) and cable release.
- Use spot focus and select best place to fucus on. You may want to try to focus on different spots to make sure you nail the focus. A camera with live view had been better so you could confirm that focus is correctly set on the rear screen.
- If capturing a flat surface, make sure the camera is completely perpendicular both horisontal and vertical toward the surface you want to capture so the whole surface is in focus.
- Jpegs from K10D are a bit soft so you can gain in image quality by shooring RAW format and process them on a computer.
