Recently bought a seek thermal compact pro thermal imaging camera.
But there seems to be an issue and I don't know enough about thermal imaging devices to know what it is.
The device seems to record good images where there is a high thermal differential and most of the subject is above ambient.
In those cases, the image is clear and sharp.
However, when focused on objects where the temperature is close to ambient such as the dashboard area of an automobile at night after everything has cooled down, the image is VERY grainy and hard to make out.
I think it's a problem with my particular camera because I have seen images of automobile dashboards that other people and posted on YouTube and the image is Far sharper and clearer where mine would be grainy and almost of no value image quality wise.
The best way I can equate this is to compare it to regular photography where the light is low and the image is underexposed resulting in a very poor and dark image with a very grainy appearance. It's not "focus"....it seem more of an underexposure problem.
But I'm not familiar with the properties of thermal imaging devices and whether they can actually have an underexposure issue since the image is created by temperature differential.
Any advice would be appreciated.
