Getting Focus on GemCam Pro

Quick Answer

Start with the GemCam Pro as close to the jewelry as possible, then slowly pull it back until the image snaps into focus. If blurriness persists, clean the lens, reset autofocus in the GemHub, or use the manual focus slider.

Before You Start

GemCam Pro is connected to your computer or laptop via USB-C data transfer cable

GemIQ is open and detecting the camera

Jewelry is placed inside the GemLightbox Pro

Steps

Position the camera correctly

Place the GemCam Pro as close to the jewelry as possible, then slowly pull it back until the piece comes into sharp focus. This is the fastest way to find the correct focal distance.

Adjust brightness after focusing

Once the image is sharp, use the brightness slider in the GemHub to fine-tune exposure before capturing. Do not adjust brightness before achieving focus.

Clean the lens

Use a microfiber or lint-free cloth to gently wipe the GemCam Pro lens. A dirty lens is one of the most common causes of blurry or hazy images.

Reset autofocus in GemIQ 

Toggle autofocus off, then back on in the GemHub. Wait a moment for the camera to refocus.

Use the manual focus slider

If the image is still blurry after resetting autofocus, locate the manual focus slider in the GemHub and adjust it slowly until the image becomes sharp.

Enable grid lines

Turn on grid lines in the GemHub to help center gemstones and keep framing consistent across shots. Reposition the camera or adjust the lens angle as needed.

Check the cable connection

Unplug and firmly reconnect the USB-C or USB-A cable. A loose connection can affect camera performance.

Update or reinstall GemHub

If focus issues continue, check that GemHub is updated to the latest version. If the problem persists, reinstall the app.

Expected Result

The videos and images in the GemIQ appears sharp and well-exposed. Autofocus engages when toggled, and the manual focus slider responds smoothly to adjustments.

If This Does Not Work

Try a different USB-C cable or a different port on your computer.

For oversized items that cannot be fully captured with GemCam Pro, use the GemHub for overhead or wider shots.

To add brightness and depth, open the mirrored cover on the GemLightbox Pro — this reflects additional light onto the jewelry.

Common Mistakes

Starting with the camera too far from the jewelry — always start close and pull back slowly.

Skipping lens cleaning when images look slightly soft or hazy.

Adjusting brightness before achieving focus — always focus first.

Not fully seating the USB cable, which can cause intermittent camera detection issues.
