Negative Supply's LM1 is a stylish, compact all-metal digital light meter

Negative Supply has launched a pocket-sized digital light meter on Kickstarter, the LM1. The LM1 is designed to measure ambient light, aiding in accurate exposures, and it also measures color temperature, aiding in determining which filters or film stocks to use in a given situation.

The LM1 supports 1/3 stop adjustments for ISO, aperture and shutter speed via its 4-button design. The LM1 has a dedicated sync port for flash metering, complete with flash mode and remote triggering options.

With an integrated rechargeable battery, the LM1 promises up to several weeks of standby. The battery charges via a USB-C port and is fully charged within a couple of hours. The device includes an automatic sleep mode to help extend battery life in the field and includes a quick-wake feature, allowing the LM1 to be used nearly instantly.

The pocket-sized design is one of the primary selling points of the LM1. The device is 44mm (1.7") wide, 90mm (3.5") tall and 15mm (0.6") deep, making it only a bit larger than a roll of 120 film. The LM1 features an all-metal body that is CNC-machined from aviation-grade aluminum or solid brass. There are multiple scratch-resistant anodized color options for aluminum LM1 and a black finish option for the brass LM1. The buttons and bulb are custom-molded, too. The device includes a strap attachment anchor, allowing you to carry the LM1 around with your favorite neck or wrist strap.

With its compact size and simple design, the LM1 has been designed for single-handed use. The light meter includes a backlit display with multiple viewing modes suitable for varied environments. The display has 144 x 168px resolution and is a TFT-LCD display.

Prototype LM1 in Negative Supply's workshop

There are many light meters already on the market, so why make a new one with the LM1? The Kickstarter campaign states, 'The electronic meters currently on the market are bulky, plastic, and don't live up to the look and feel of the cameras we've all grown to love. We decided it was time to change that.'

Saxon McClamma, Co-Founder and Director of Design, adds, 'The LM1 is the most complicated tool we've designed, and everything needed to come together perfectly to bring it to life. The experience of our incredible team of programmers, engineers, and manufacturing partners allowed us to create an elegant, timeless design without compromising functionality.'

Left: Brass LM1 after wear testing. Right: Anodized aluminum LM1 is available colors.

The LM1 has already eclipsed its funding goal of $50,000 and reached its first stretch goal of $100,000, which adds built-in shutter speed testing to the LM1. The second stretch goal of $125,000 has nearly been reached at the time of writing, and that goal adds filter factor calculation functionality.

Backer options for the LM1 start at $379 with special early bird pricing. The eventual MSRP when the LM1 launches (November 2021) will be $479. Additional backer options include an aluminum LM1 with special green, slate gray or silver colorways for $429 (regularly $529) and the LM1 in brass for $599 ($749 MSRP).

IMO it's very expensive for what it is. to its credit, it has a color meter in addition to exposure meter, which _could_ be its redeeming feature but the campaign doesn't say anything about it other than "it has one." also, opting for an internal (probably non-user-replaceable) battery seems like a dumb idea when it can easily be powered by 2 AAA batteries even at the expense of slightly increasing the size to accommodate the battery compartment.

Companies like this, especially on KS should do some research into what customers (I.e. photographers) want before asking for funding. That way it will be a good for both customers, KS funders and the manufacturing company. Unless of course they are using DP as feedback before they go into full production??

Will it measure by the light of a quarter moon?
My Calculight XP does and it cost a lot less. Also smaller than a pack of cigarettes. Attachments available so I can measure exposure directly off the ground glass of a view camera - through the lens as well as spot meter readings.

This is probably a nice meter but unless the rechargable battery is easily replaced it will one day be in the rubbish bin.

But doesn't a larger sensor capture a greater amount of luminiferous ether, increasing the ability to phlogisticate the sensor pixels?

kb2zuz

There is no equivalence to exposure. If you're using an f/16 lens with a sensor at 100 ISO you'll need about 1/100th of the second regardless of the sensor size.

There can be variations but that is due to the transmittance of the specific lens (T-stops vs F-stops) and has nothing to do with crop factor.

Crop factors only are only a construct to help visualize differences going from a full frame sensor vs a crop sensor.

2 months ago
image365

I understand that there is no equivalence with exposure, so why do people still say that an f1.8 m43 lens is equivalent to f3.6 compared to full frame, when talking about light gathering and not dof ?

2 months ago
kb2zuz

Because again people try to make approximations to understand but people end up going down a rabbit hole because solving one problem leads to another.

A 25mm lens on M43rd gives a narrower field of view than 25mm would on a 135 format ("full-frame") camera. So yes a 25mm lens on m43rd gives a field of view that is similar to 50mm on 135 format (we'll ignore differences in aspect ratios of the sensor)

But then when you use a 25mm lens at f/1.8 the depth of field isn't the same as 50mm at f/1.8. So the depth of field is similar to a 50mm at f/3.6 (we'll ignore differences in fall off)

But then if you use f/3.6 for exposure your image will be under exposed... because it's not really a 50mm f/3.6 you're using. It's a 25mm f/1.8. You could try to figure some kind of equivalent ISO setting and say that 100 ISO on M43rd is like 400 ISO on 135, but you're just driving yourself crazy, cause you have to remember to actually set your lens to f/1.8 and 100 ISO.

People take things too far.

I used to have a Minolta and a Sekonic flash meter when I was shooting with film long time ago, both are very good meter, I used them to measure the output of my Metz flashgun (45CT3 or CT4 I forgot) and I got higher than advertised figure in full manual, where most Japan made flashguns are near a stop under back then. I am considering to purchase a new meter while I am 'going back' to shoot films. In camera meter can never replace a standalone one due to the way the measurement taken, but nowadays very few photographers still carry a meter, with digital and high dynamic range sensor and post can fix most metering problem.

Handheld light meters are becoming more and more of a niche market and maybe this sounds obvious, and maybe this has been the case for the past 5-8 years since in-camera metering has gotten so good, and for most people, it works. (I mean with some you have to figure out how your camera meters - and by that I don't just mean knowing when you use what metering mode, but knowing if your camera tends to under/over expose in certain situations with various metering modes). Once you can master that with your camera, you can usually get by with the built-in reflective meter.

I rarely use the handheld meter I have as it is... and it stays in the bag & only gets used (literally) a handful of times per year. I'm sure there's a market for this, but probably not that big, and you could probably find something from Sekonic, that's used but probably with more features and for less than what you'd pay for one of these. Plus then there's the question about things like wireless triggering support

And maybe more pointed is with everything (with few exceptions) moving to mirrorless...there is no exactly any mystery about your exposure being good or not.

And the display looks like an off-the-shelf 128x128 monochrome OLED. I've built projects with these and they are compact but very clear and legible.

One thing skeptics need to realize is you no longer need to be Sekonic or Gossen to build a straightforward light meter like this (or the various shoe-mount ambient meters that seem to be advertised everywhere nowadays.) Good light meters used to require sophisticated analog circuitry (or, later, custom application-specific integrated circuits) but now highly accurate lux and RGB sensors, OLEDs, and microcontrollers are off-the-shelf items that any competent designer can use, and contract manufacturers for cases and circuit boards are accessible to anyone with the right knowledge and connections. In this environment, the main constraint on the quality of the end product is how good the designer's ideas are... although don't expect leading-edge features such as Sekonic's HSS metering capability.

"One thing skeptics need to realize is you no longer need to be Sekonic or Gossen to build a straightforward light meter like this"

Yeah but if you are pricing it at Sekonic levels you need to be able to compete. I build a lightmeter with my 3d printer and an arduino over a weekend. Sure it doesn't look that nice but it was also way cheaper. If you sell something at Sekonic pricing it shouldn't be a straightforward lightmeter, it should be a really good one. It shouldn't be at the level of my 30$ arduino project with a nice metal case.

#Ranger 9, cheap and accessible parts, is that why it costs over $400? I can get a Sekonic Flashmate for under £200 on Amazon and that's far more flexible.

Buying a Gossen or Sekonic is exactly what I personally would do (if I didn't already have a perfectly good Minolta Flash Meter IV) but I'm not everybody. Some people might prefer a specific feature of this meter, such as the rechargeable battery or the relatively compact size (ya gotta admit that the higher-end Sekonics are getting pretty chonky.)

My point was that now that electronics designers can easily create niche photo products such as light meters using off-the-shelf components, the only thing that will differentiate a good one from a bad one will be how well-thought-out the design is... something that's hard to evaluate from a Kickstarter spec sheet. That's why I hold off on these sorts of things until reviewers I trust have finished units in hand...

@Ranger 9 - “ designers can easily create niche photo products such as light meters using off-the-shelf components, the only thing that will differentiate a good one from a bad one will be how well-thought-out the design is”.

Totally agree - I have a Doomo light meter ( https://www.35mmc.com/08/02/2021/doomo-meter-d-light-meter-review-for-the-analogue-experience/ ) that I love, and a V201X ( https://austerityphoto.co.uk/blinded-by-the-light-the-v-201x-light-meter-on-test/ ) that I like not so much :-) I suspect inside they're pretty much the same, just a much more intuitive interface in the Doomo.

Good:
- Small - most light meters are a bit big
- Third-stop controls - this is very helpful, given that all cameras now work with 1/3 stops
- Colour temp reading
- Metal - I guess this is nice

Bad/not sure due to insufficient info:
- No option for reflective reading or flat-disc incident reading?
- No digi-analogue scale?
- No exposure range/average reading?
- If front button is main reading button, this is in most awkward place for single-hand use. None of the controls are explained.
- Non-replaceable battery?
- No flash/ambient percentage reading
- Expensive for its features

TBH, I'm irritated by the lack of any detail about features, modes, controls etc. I'm not the kind of person who is swayed by soothing music and shallow DOF lifestyle videos. I want to know what I'm getting for my (substantial amount of) money and the presentation hints at - not a lot.

Fair point, but form factor, screen and button layout are shown and presumably fixed, so they must have a good idea of what the buttons will do, modes it will have, roughly how it will work etc. They could have given more details and just put in a proviso that minor details could change. Just feels a bit like they are obfuscating the functionality details with aesthetics and lifestyle sheen.

More accurately: "Kickstarter is not always a scam."

Sometimes the finished article exceeds expectations and compares well against commercially-developed products. Sometimes it's a usable but slightly underwhelming effort with a few rough edges. Sometimes it's basically a series-produced hacker/maker project that may be fine with a bit of DIY; sometimes it's a barely-functional disappointment; and sometimes it IS an outright scam that never delivers anything workable. I'd say the vast majority fall somewhere in the middle of this range.

Backing Kickstarters can be lots of fun if you're a tech enthusiast, have an optimistic nature, and can afford to write off an occasional bad investment. Me? For something like this that I'd expect to use often, I'd rather wait for a real product and some unbiased reviews.

Having backed 135 and 120 film holder, it is my opinion that negative supply overcharges their products by a lot. Overengineered where it is not needed (a ton of aluminium) and missing quality where it should (tolerances/play,and finish). In short, you're not getting more with the higher price. Still nice but should be half the price. Can't testify for other producs (read reviews though) but it looks like they keep on going with that trend. The sound of "Director of Designs" made me smile. All the best for them, they had nice ideas and certainly helped the film scene, but eventually, smarter, cheaper and equally well built competition is going to get them.

I used color adjustment filters just last weekend, when I was shooting on a theater stage with a fiendish mix of LED stage lights, tungsten stage lights, and electronic flash. I had to gel all the lights to get them to roughly the same color balance, then set a custom white balance on the camera to agree with them all. Not having a color temperature meter, I had to do it by trial and error, and even then the final adjustment wasn't as close as I'd have liked (needed a lot of tweaking in post-production.) A good meter would have saved me some time there, although I can't afford the Sekonic C800 and a not-so-accurate color meter (like the one in the phone app I have) wouldn't have been worth the bother. Will be interesting to see if this one can cut it...

The dome should be made smaller and put in a wearable item designed to look like a wristwatch, pendant if a necklace, buckle of a belt, etc with the electronics hidden at the back of or inside these items. The measurements should be sent directly to the camera via Bluetooth, when triggered by a half-press of the shutter button, so that the camera can make adjustments automatically or suggestions on the EVF just before the picture is taken. Other easy to remove items can also be considered. Perhaps the single dome can be replaced by a group of very small ones for hair bands, sunglasses.

Kirnbichler

Cameras do capture reflected light, but an incident light meter does not measure reflected light.

See what kind of light meter ist used in what situation. The reflective light meter is used from the photographers standpoint, it is pointed at the motive and "sees" the light the camera "sees".

The incident light meter in contrast is used from the motive's standpoint and pointed at the camera (or not really pointed at all, since it's cupola is intended to reduce the depencency for the direction the light comes from).

See the very first image in the link I've posted above -- there a guy holds an incident light meter in front of the model, pointing more or less toward the camera.

Get the difference?

Kirnbichler is is correct. Unless you use a diffuser attachment, phones cannot act as incident light meters, and this is an important difference. Incident metering is generally preferred for such things as studio work, portraiture, still life etc.
There are also other reasons why a dedicated device might be better than a phone app:-
- believe it or not, not everyone has a smartphone
- if they have one, not everyone wants to take a smartphone with them while doing photography
- smartphones don't generally have lanyard attachments.
- dedicated light meters have dedicated controls and are easier to operate with one hand than a phone app. This is pretty important.
- light meters have much longer battery life than phones
Not saying a phone app can't work well, but it's not a direct replacement for a dedicated light meter.

Nameless it's not the phone, anyone can make an app, how do you know the characteristics of each phones sensitivity? I also don't enjoy using my phone for anything other than a mini pc..

From Sekonic, 70 year old company specializing in light meters

* l208 - £103
* L308 - £191

Or from Gossen, who’ve been making light meters for 88 years
* Digisix 2 - £129

All available now for next day delivery

Alternatively you can support a Kickstarter for a light meter from a very young company which specializes in film carriers for digitizing film with a digital camera. And pay $379 (normal price $479) with a delivery date in November 2021.

What am I missing ?

Well it does offer colour temp too which makes it a bit unique but I'm assuming there's a reason (beyond just market segmentation) other manufacturer's keep their light and colour meters separate.

In the article the rep for this company says those other meters are all plastic, but theirs is metal - like the film cameras they like.
I still like the little Gossen flashmeter for $230 https://static3.nordic.pictures/29277824-thickbox_default/gossen-digiflash-2-lightmeter.jpg

If you go for it, you may be missing your money.

@the sage knows: Well, of course light measured with a metal meter is much more precise, warm and analogue than light measured with a plasticky light meter such as the Gossen lightmeters mentioned somewhere in this thread.

I've got a Gossen Lunasix 3, made somewhen in the late sixties or early seventies, in a grey plastic case. And a Gossen Profisix (with spot meter attachment, and fiber attachment for measuring on the focusing screen of my 4x5 camera) - also in plastic case.

Was no problem then. Why should it be now?

@Simon Barker I’m a film photographer who has more than five light meters so I might well be the target audience for this, but I’ve never used a colour temperature meter for film. I’m not even sure if tungsten films are available now ? The new Ektachrome is daylight balanced (and gorgeous ).

@The Sage Knows most of my light meters (and cameras) are plastic (although sometimes with a magnesium alloy frame :-) )

Would have been useful if the values from the colour-meter could be used to adjust WB in Photoshop etc.

Easier to just use a whibal card for that by clicking on the image of it I would say.

Times have changed and I hardly ever use my light meters anymore. I have a nice (and old ) sekonic flash/light meter which I almost never use except for the flash and even then not too much. The colour temperature function is attractive BUT it is way too expensive......I have not gelled lights for a generation.

Crazy. Sorry. Surely there are a plethora of cheaper and equally effective options out there?
