Wonderful tutorial thanks Michael. My Looking Glass Portrait is on it's way to Australia!
Great video! Fantastic recap of the product and software. Re: battery: I've had success running off an external battery, but only using their USB-C cable- USB-C on device to USB-C on the battery. No other cables or adapters have worked for me so far! But it's very nice to show people on the go. Re: reversing the order for the series, I definitely agree. I discussed with them on the Discord and they say "support for both directions is in the backlog" so that's positive.
Thanks Dave. It would be nice if a shorter cable would work for battery power.
THANKS, Michael for sharing your Look at the Glass :) Great job as always.
Thanks Ron
Another really informative tutorial! Many thanks, Michael
Thank you Rob.
Excellent review! Thanks for all the detail and demonstrations
Amazingly informative. Thank you! I assume the aspect ratio of the video being out is to basically reduce the artefacts from mpeg compression.
Super presentation Michael, thank you for your very informative video!
Thanks Andy.
Thanks Michael, great and informative review. I completely agree with you on the use of depth maps. I like the way you describe these as having a "embossed" effect. I think that is a very apt way of describing the effect. I much prefer actual stereoscopic photo pairs to those re-rendered from depth maps. But that of course becomes difficult when having to deal with a multitude of views, but I presume with lenticular work you would be used to that. I've just received my Portrait (always takes a little longer to Australia) and if it were not for your video would not have even noticed the headphone jack… but where is the volume knob?
That is a good question about the audio volume control. I know my Apple wired earbuds have a volume control, I never tried changing the volume the one time I played back the 3D movie sample.
Hi Michael! Very interesting video. A question, this only shows depth and parallax left to right, with nothing up and down. Does this break the illusion of the 3D affect and make it look "unreal" to the average viewer? Does the image look/feel 3D even if you stay stationary and do not move?
You're right - horizontal parallax - not vertical parallax. The device is viewed from straight on and our two eyes are offset horizontally, so the lack of vertical parallax is not a practical issue.
Thanks
Hi Michael, really enjoying your videos. Do you have an opinion on consumer level stereo cameras like the Vuze XR or the Insta360 Evo? Do you think they would work as an input source for the Looking Glass? Keep up the excellent videos!
I don’t feel either of those would be a good match for the looking glass. The best thing is a single camera on a sliding rail, and the next best would be a 2D image with matching depth map.
Fascinating video - I’ve just received my Portrait and started experimenting. I’m trying to work out how to create a “Lightfield” image series from After Effects and just wondering if you think it’s better to horizontally move and rotate the (virtual) camera towards the subject or simply to move it?
I would move the frames in X to set the 0 point. 2nd choice would be to toe in.
@@MichaelBrownArtist Thanks - I've got some nice samples playing - I now need to go back through your video and learn properly a second time round. Thanks again for a fantastically informative film!
Excellent Video, I have a question, the images can only be seen in 3D in the mirror? or after converting, do they remain with the effect and can be downloaded and viewed outside the mirror? Thank you very much.
It is not a mirror. It is an autostereoscopic display. You need the device to see them in 3D.
Thank you very much for the information, I thought that the device was not necessarily needed to see the 3D images, since on their platform (lookingglassfactory.com/account/2dto3d) they promote a paid software that converts 2D images into 3D and They do not mention that the images that are converted are exclusively for viewing on your device.
Hi Michael, I'm curious, how do you find that the Looking Glass compares to the Lume Pad in terms of visual quality?
Also, have you tried any of the VUZE cameras? I'm thinking of getting a Vuze XR camera
Two completely different experiences. Lume Pad has a 50 plus degree viewing angle and works in portrait orientation. The Lume Pad works in either Portrait or Landscape, but has discreet viewing zones separated by pseudo s optic zones. Both could use more resolution. If you’re primarily interested in stereo pairs, I think the Lume Pad in ST mode is very nice, but you have to hold the tablet in the right position for the best view. I have no experience with the Vuze, but have looked at samples from the device on my VR headset and wished it had more resolution.
I also own the Looking Glass Portrait. I'm also currently experimenting with a photo rail and a camera. Does the camera only have to move horizontally or does the camera have to make a slight rotation around the subject?
I am not getting any satisfactory results yet.
You can do it either way. In both cases you need to align all the frame at your defined 0 point (like the eyes in a portrait). I usually shoot with a linear rail because it's easier. For the best portraits I prefer rotating around the subject.
@@MichaelBrownArtist Is that only possible in AE or is it also possible with Premiere Pro?
Years ago I tried something with tracking in AE.
But I can remember that it was very complicated. Do you have a tutorial that describes the way?
@@toralfczerniak8250 , I have never tried tracking in Premiere. I don't have such a tutorial but it is a good idea that I should create something like that.
@@MichaelBrownArtist Such a tutorial would be a great idea Michael. I thought that only good results for portraits can be achieved with the looking glass. But the pictures of women on the stairs or at billiards are fantastic. Instructions on how to take the pictures and then edit them in SPM and AE would be so helpful. I bought an iphone especially to take the photos with depth information. But that doesn't satisfy me at all. It doesn't really look like 3D or hologram.
I'm glad I found this video.
@@toralfczerniak8250 , yes iPhone depth map photos give an embossed look but not really "look around 3D" I prefer actual mult capture.
Hi there, are there any software to quilt images for the looking glass studio portrait display preview?
I used the Contact Sheet feature in Adobe Photoshop.
Can you upload some of the files you are most proud of so we can test them on our Looking Glass's
That's a good idea.
Another question: if Looking Glass only produces horizontal parallax, why do they use the "quilt" format, which implies vertical and horizontal perspectives? Why not just position all 40 (or whatever) images from left to right in a single row?
A quilt or grid format has been used for years in autostereoscopic applications. It's probably used because al the images fit in a rectangle for easy viewing on screen, instead of a very long file like you might have with 100 frames. I guess because I've seen such formats over the years I didn't question it. (2003 Stereographics SynthaGram 9 tile format) I can see how someone who wasn't aware of prior art could assume it had both X & Y views (but it doesn't - horizontal only). Thanks for sharing that comment.
The Looking Glas homepage says that it is better to record a video with the rail and then win the frames. How would you do it, single photos or a video?
I've done both. You can get higher frames rates with video. I have used 240fps in the past for some 3D portraits. Generally I prefer using a still frame camera shooting RAW. I'll shoot about 20 fps for a burst of 70 or so frames. I like that method because I can shoot in RAW format and have more flexibility in exposure and color adjustment if needed.
@@MichaelBrownArtist I come from stereo photography I know the problem that the left and right images have to be absolutely syncronous. If you take 70 individual photos, for example, what if the person moves slightly or blinks while taking photos? How do you get proper ones results for the looking glass?
@@toralfczerniak8250 , you don't notice tiny errors because the frames end up optically averaged. I typically do the geometric correction in SPM and alignment in After Effects. The results are very good.
@@MichaelBrownArtist Can you please do a tutorial in which you explained all the steps in detail?
@@toralfczerniak8250 , at some point I plan to do that but I have more immediate projects to finish.
Does anyone know what the real looking glass does or did and why did they hit a wall @2021
Here is it: czcams.com/video/1-6yxyuugHQ/video.html
How can I get one of those to review?
Nice video! I've just received my Looking Glass Portrait frame, and have been playing with it for a few days. You're answering some great questions that aren't really covered in their documentation.
Here's one question I can't figure out - maybe you can help. The Looking Glass Portrait claims to be a "Lightfield Display." I've been trying to understand exactly what that means. Digging through their tech specs, they also call it an "Advanced high precision lens and microlouvre array." Does this mean "a lenticular screen glued to the front of an LED display"?
Yes, a lenticular sheet bonded at an angle to the panel. Their use of lightfield is that it has an approximately 50 degree horizontal viewing angle. It is not a lightfield display in all directions. Just like the displayed images are not really holograms.
