Camera out of focus or normal?

Hi there,
I think my camera lost its focus…? What do you think? The right bottom corner is quite blurry…

Blurry bottom right corner is normal on my machines. Understandably as that area is less than an inch away from the lens.

Oh ok. So for you everything looks ok and I don’t have to worry?

I think that is pretty typical. My first camera was replaced after it developed dark “blotches”, but it looked much the same as this.

300mm mark at front left edge of the plate.

I think it is an inexpensive camera with a relatively wide aperture to deal with the low light levels in the printer, which limits the depth of field.

On a somewhat related topic, I adjusted the display controls on my PC while using this view and found that I could make a significant improvement in the brightness and contrast. It’s worth checking…

I wouldn’t worry about it. It is good to clean the lens every so often especially if your printing ABS/ASA regularly.

That’s the way cameras work. For any given aperture, you only get so much depth of field (area in focus). I’d guess the camera is focused toward the middle of the bed meaning there will be an area of in focus just ahead and just behind. Normally with such small sensors you can actually get lots of depth of field, but I’d imagine with the dungeon-like interior they have, the cameras are pretty wide open as far as the aperture, so that means less of the scene in focus.

Everything in life is a tradeoff.

The phenomena you’re witnessing is called Depth of Field and is a function of optics in physics. It is often used by photographers to achieve a dramatic affect. Look at it this way, you get it for free. :grin:

Here’s a summary I found on the web that explains it better than I can.

  • Depth of field (DOF) determines the range of distances within a photo that appear sharply in focus.
  • Shallow DOF: Limited area in focus with foreground and background intentionally blurred; ideal for isolating subjects, often used in portraits.
  • Deep DOF: Broader range in focus, both foreground and background elements are clear; useful for landscapes and detailed scenes.
  • Factors Affecting DOF:
    • Aperture: Wide aperture (small f-number) creates shallow DOF, narrow aperture (large f-number) results in deep DOF.
    • Distance to Subject: Closer subjects tend to have shallower DOF.
    • Focal Length: Longer focal lengths can create shallower DOF compared to wider lenses.
    • Sensor Size: Larger sensors often produce shallower DOF.
