I am having a bit of difficulty scanning a black object with details, but not when I scan the same object in white (I tried both auto and manual exposure mode as well as selecting the black object). What is the recommended setting for scanning a black object with the smallest target point distance?
Spray or powder your object. They say laser scanners are better for black objects, not perfect. My rule of thumb: if the laser reflection is not bright off the object, you need to spray it. An upside of spraying, it seems to acquire points (makes scanning) a lot faster. I try to keep a can of ASUB blue in my scan bag. There are a ton of other sprays and DIY solutions that are cheaper, but I am lazy. I hate marker dots, so I got a Trackit. I hate cleaning up talcum, so I use ASUB. There are cheaper options but I am paying for the convenience.

Hi @tingc911
The tip Bruce give you are valid and I do the same , no time for struggling .
The object color don’t really matters here but what the material is made off , if it absorbing all the blue laser even if you set up black object and used the laser at full brightness there is only one thing to do , 3D spray as Bruce stated.
But I am suspecting you let the depth exposure too much up , set it back to level 7 , never use it at maximum together with full laser richness as it will make the sensors blind .
If not Auto settings works , only 3D spray will but try to reduce the depth exposure leaving the laser brightness at full range .

And photo of the item?
Ive scan black plastics without problems. However black car paint is shiny, black and needs spray. Also anodized black will absorb the laser lines. So it will also need spray
hello
ive scanned a full black car ( audi A4 ) with absolutely 0 scan spray aside from the headlights. I find taking it out of auto exposure and manually controlling laser brightness and exposure was part of the success.
Love my Trackit!

Hi @MachChicken
Thank you for sharing your successful story , the color black is not actually the issue , it is about the absorption . Black cotton can scan at the same laser brightness as the white cotton , the same goes with other materials ,
So one can absorb more light than the other yet have the same color and yes they require different brightness settings , the most mistake what users do is changing the depth exposure to maximum , make it blind .
