For multispectral image analysis, I am using the set of wheels with bandpass filters from 365--940nm. Taking a full set of photos allows software to map the spectral curve of various materials in that range, and, depending on the material, can reasonably identify or narrow down ID possibilities.

Limited a bit by space, these are some sample images taken with the visible range filter wheel:

450nm:

550nm:

650nm:


After taking a full set of images with each bandpass filter, I will put them through multispectral imaging software to process the spectral curves and allow me to narrow down material IDs.

My recent discovery of a website dedicated to stock photography has been nothing short of transformative for my creative endeavors. This platform boasts an extensive and diverse collection [url=https://depositphotos.com/photos/lebron-james.html]lebron james[/url] of high-quality images, covering an array of themes and styles. As a content creator, it has become my go-to resource for infusing my projects with captivating visuals, whether I'm designing websites, crafting marketing campaigns, or curating social media content.
