boarderphreak: Vertical video? In IG's tiny little format? Yeah, no...

Jack, that is of course the idea. Film vertically, watch vertically. No letterboxing, full screen = video.

JensR: How are they going to assess whether a video is vertical or horizontal? And if someone uploads a horizontal video, will it get blocked?

Thanks Bryan, that is interesting. The disobedient nerd in me wants to mess with the metadata to trick the app into thinking the horizontal video is vertical. Probably would get me banned though :-O

Chris2210: Am I missing something obvious here? I expect this is mostly going to be used with 35mm film, [but the same goes with larger formats], so what's to stop you putting a piece of tracing paper over your iPad and holding down the film with anything dark enough and heavy enough to hold down and mask the film?

£25 is not a lot, but a sheet of tracing paper and any assortment of things you might easily find around your house saves you your pony...

The product is effectively finished. All he needs are custom rubber parts. As such, I'm am confident that I am right when I say that this is a time consuming device when you digitise rolls of 35mm.

AlpCns2: Now THAT's a full-frame sensor, for all those shallow-DOF fetishists. Much better than those puny 24x36mm sensors. Comes with a fork lift truck to change lenses.

Grogan, you are right - when I was talking about cost prohibitive, I was specifically talking about the digital sensor (and by extension the electronic hardware necessary).

milkod2001: 10 bucks for PS and Lighroom is not that bad and makes no difference if you pay monthly or annually. The issue is when you also need AE, Illustrator and some other apps. The price skyrockets then. Should be $10 extra for any extra app or more apps you get price should be cheaper then.

No, the issue is that once you stop paying, you end up with an effectively defunct piece of software that you have paid hundreds of dollars for.
I'd probably switch if Adobe would guarantee that after one year of subscription, the last version I received will become perpetual, so I could stop (and restart) at any time.

Wye Photography: How about $5 per month for Lightroom Classic only.

Enjoy Classic for a few more years I expect the whole lot to migrate over to the cloud.

Sounds ok. By the time that runs out, the LR alternatives should be so good that jumping ship makes sense.

Rensol: We did something similar in 2013 and tried to bring it to kickstarter. But they did not approve it.
It had all these guys have + right angle camera mounting.
Funny,,,
That project is dead and the page is abandoned but here is a link for it:

Nice! 90° mounting is so important!

White semi-transparent plastic sheets can be bought cheaply off ebay.
And if you think this device is quick to go through rolls of 35mm film, I disagree.

mike80: 120 film is not 120mm.

I don't think he says that in the video? He says 120 film up to 6x9 - which in this case is cm. It is confusing, because the next measure he says is in inches.

For people with larger formats this is a very nifty solution and while DIY will get you there a bit cheaper, it won't be worth the hassle for most. I am not so convinced for 35mm folks.

I am working on something very similar myself for 35mm film.
The biggest problems my solution has, are shared with his:
1) It works well on a single image, but if you want to digitise a 35mm film, you will be there forever.
2) assuring perpendicularity when taking the photo.

For 35mm film, there are of course "digitiser tubes" you can mount in front of your normal lens (with a dioptre element in them) or your macro lens (without any elements). I have found these to be also unsuitable for handling a whole 35mm film.
I had a look into something that would allow me to clamp-snap-release-move2next-repeat cycle and provide better perpendicularity by supporting my macro lens via its lens hood.

Stefan Sobol: This device is nothing but a film holder. Don't see that it actually adds much value to the process, but I guess that's reflected in the price.

glass will cause newton rings, so you need a special anti-newton plate.

If you look at lenses and cameras for 8x10 (inches) sheet film, they are heavy and bulky, but certainly not impossible for a single human to work with. This sensor in a modular mount could even adapt to these old view cameras and of course new ones could be made. I am aware this is cost-prohibitive for most photography outside science and military - for now.

DotCom Editor: Is this similar to Canon's Diffractive Optics "DO" lens technology?

To add another link, there is some confusing terminology to go around. The "phase fresnel" lens is different from the fresnel lens in a lighthouse light. The Lighthouse lens is a refractive optics (like normal lenses) just arranged differently, the "phase fresnel" lens is a diffractive optic...

agrek: Another bag review... 🤔 soon, I guess, we’ll read about shoes, summer jackets etc.

Is this the point where we discuss the superiority of backpacks? I brought an axe that needs some grinding and if someone could bring a dead horse, we could get the party started!

Matt_Anderson: Are the owner(s) the Alt- Right fanatics still ?
I love their hardware, but like the owners of Uline, I won't buy their product given the alt right agenda.

I'm not sure I'm late to the party, I haven't bought RRS ever, so I think my track record is flawless ;) Instead I bought something probably made in China by a company that probably has an even shadier human rights record but I claim plausible deniability >:(

Michiel953: Barney, ha! Domke bags. I have an F2 (wax variety, doesn’t seem all that bigger than the 6) and it’s a much better bag than any stiff upper lip Billingham. I hated those.

Your list of items “in the bag” is endearing, and (vaguely) resembles the bewildering list of odds and ends I stuff into my F2 when travelling. It really is a great bag.

My everyday (business and camera, whichever one) is a Tumi (ballistic!) messenger bag with a Billingham insert. Amazing what that one can hold, 13” laptop included!

"There's no doubt that the image quality of those bags is superb"

Either I am missing something here or you had a mental slip of the tongue :D

Implying people are "organising a boycott" because 5 people on a gearhead website say they won't buy their stuff seems a little hyperbolic. And even if they were, it would be classed as protected speech.

And yes, most progressives swallowed their pride, voted for a Democrat who was not embracing marriage equality and in the end that turned out to be the right decision.
Obama's history with that question is a bit more difficult though. You could say he is a flipflopflipper. Or you could say he played his cards right.
http://www.politifact.com/truth-o-meter/statements/2012/may/11/barack-obama/president-barack-obamas-shift-gay-marriage/
It is misleading to think that supporters of marriage equality only care about that one issue in an absolute manner. They are able to do trade offs as you have to in a two-party system and they are able to see nuance.
There was no doubt in 2008 which party would be more likely to eventually support marriage equality.

Astrotripper: While I love the idea of being able to use a 35mm film SLR with instax film, this device just kills all the appeal of a classic camera. This is just ridiculous.

Why won't any company just create an actual camera that takes instax cartridges? Make it a clunky retro metal body with mechanical controls, like the old ones, and provide adapters for legacy mounts. You might get something that might actually be usable.

thanks, was trying to find actual format size but struggled, "everybody" said 6cm.
Found it now - for example the Kiev 60 http://mattsclassiccameras.com/slr/kiev-60/

I think 6x6 should be okay for the expected quality from Instax film - what are slightly dark corners on a Polaro.. ..I mean Instax picture?
62x62 vs 60x60 (or thereabouts).
Here's a cool DIY project using a Kiev (or Hasselblad)
