You HAVE to remove the lens from the front of the hologram laser! The small red dot the laser produces,and large brass cylinder at the front of the laser shows me you haven't! The light it produces should be a wide cone-shape completely filling the holographic plate.
The laser needed to be moved farther away from the object, to provide a wide enough beam, and the beam should've been diverged more. You really needed the brighter inner portion of the beam to cover the plate, and object. that's why it takes five minutes, or more.
This kit actually works really well. Go watch Make Magazine's video on the kit. They use it correctly and make a few great holos. Mashable didn't do theirs correctly and that's why they got poor results.🤷♂️
This guy doesn't understand that you have to illuminate the whole subject...seriously? If you have a diverging beam, you just move it back farther. Also, he doesn't tell you how to set the exposure time; it's 30mJ/(power of laser {in mW/cm^2}/area of beam{in cm^2}) = seconds. For my 100mW green Laser, shooting a 5 x 7.5 cm plate, it's: 30mJ / (100mW / 37.5 cm^2) = 11.25 sec LitiHolo says you can't overexpose, so I use 20 seconds. Time is important, because vibrations between the subject and the plate can change the interference pattern {you only have to move 1/4 of wavelength to cause trouble}. This guy is touching the table, and breathing, and talking during the exposure; all things which wreck a hologram. Despite all of this, he actually got a clear image --astounding! I learned Holography in an elective class in college. We had magnetic bore locked Lasers, a $10,000 Newport table, spatial filters, 1/10 wave optics, etc... Then we had to develop the film in a dark room. LitiHolo has made this EASY! I highly recommend their plates, they just work great!
From the article: "Before we dive into the product, you should know that what the Litiholo kit creates are better described as holographic images instead of holograms." If you have no understanding of what holography is, maybe you shouldn't do a review of it?
Thank you for this review! They really should have given more clear instructions... I'm very into lasers and holographic imagery, but this whole thing seems like a waste of time and money.

thats cool
Terrible review
There's no way Litiholo instructed to put the lens back on, so maybe the failure is on Mashable in this god-awful review.
