Whenever I take a photo, no matter what, I always have an issue with dark texture that keeps appearing on the model. What can I do about it? This has resulted in many of my models going to waste, and post-processing doesn't help at all. Link to my photos:

Thank you in advance for your help.

Hello piratek098,

If you mean those dark horizontal stripes in the middle of the model, they seem to be related to the dark areas on the source images that are close to the bottom of the object (and therefore the background).

To reduce such unwanted effect you can use Average or Max.Intesity blending mode, but as a proper approach I think only shrinking masks on the source images would work, so that darker parts of the object on the original images in the areas close to the mask boundaries are also masked out.

Such negative effect might be also avoided for future projects, if you use white plain background (to avoid black or colored reflections on the object's surface) or put the object on some high stand to avoid background reflections on the object's surface.
Best regards,
