Thoughts on the Reveni Light Meter

The Reveni Labs hot shoe Light Meter is the smallest one we’ve found.  But adding ‘mini’ to the name was entirely my idea.  It was a Kickstarter that my husband joined a few months ago, and I have to say one that I’ve been most pleased with.

The Reveni Light Meter has an excellent downloadable .PDF manual that starts with the basics of metering and proceeds through to the specifics of this light meter’s operation.  Each orders includes a certificate as shown above.  I’ll spare you the full description, because the manual can be examined before you make a purchase.  A summary of the key feature are below:

The Reveni Meter has an ambient reflective meter with a 45 degree cone sensor field.   It has a bright OLED display with simple menu and controls (shown below).  It has aperture or shutter speed priority settings.  Exposure compensation can be set in steps of 1/3 stops in a range of -2 to +2.

Example display of f/16 and an exposure of 4 seconds, representing measurement of the red background material.

The Reveni uses a LR44 battery.  It weighs 9 grams including the battery.  The first battery is provided (at least for the Kickstarter version). The dimensions: 0.92 in (22.5 mm) x 0.86 in (21.8 mm) x 0.71 in (17.8 mm).  Now with the basics in hand, let’s get to the testing.

Light Meter Testing

To test the Reveni Meter I first compared it to my recently refurbished Minolta SRT-101, which included a light meter recalibration.  I mounted my f/1.7, 50 mm normal lens for the test.  I was exposing Kodak T-MAX 400 @ ISO 200 (E.I. 200).  Sometimes I held the f/-stop constant and changed the shutter speed and sometimes I held the shutter sped constant and changed the f/-stop.  In both cases my results were consistent.  The Minolta Meter was 1/2 to a full stop over exposed compared to the Reveni Meter results in medium to dimmer light.  The exposure difference could be as much as 2 f/-stops in bright light or with a lot of glare, as with the first example below. The Reveni doesn’t handle glare as well as the in-camera meter

Both meters agree for the wide open landscapes……..as above.

I also happened to have my X-700 loaded with Ilford HP5 @ ISO 400 (E.I. 400) with a roll of film that I wanted to finish.  I had been using this camera to photograph my Birthday Bouquet.  So I snapped on the Reveni Meter and did a few comparison images.  Here is one example below.  The X-700 meter showed a full 2-stop difference.

Final Thoughts

In general, I trust my 35 mm in-camera light meters, especially my refurbished SRT-101 and SRT-202, which were both re-calibrated.  And the in-camera meters seemed to handle bright light and glare better.  That said, I find no faults with the Reveni Meter and can think of two special cases where I will definitely use it.  I have two wonderful cameras that are fully manual with no light meters:  my Mamiya 1000s (645 format) and my FujiFilm GW690-III (6X9 mm format).  Usually I ‘guess-timate’ an exposure using the sunny-16 reference.  But, I’m not alway photographing in bright sunlight, and multiple bracketing exposures are not practical for the GW690-III which only has 8-shots per roll.  The Reveni Meter also offer a number of meter carrying options for cameras like the 1000s, that do not have a hot shoe.    So they have it all covered.  Be on the lookout for future works featuring these cameras and the Reveni Light Meter.

IN REMEMBRANCE: 9/11

I wanted to post something for TODAY:

And I also thought that FDR’s full quote was appropriate to Remember:

“So, first of all, let me assert my firm belief that the only thing we have to fear is…fear itself — nameless, unreasoning, unjustified terror which paralyzes needed efforts to convert retreat into advance. In every dark hour of our national life a leadership of frankness and of vigor has met with that understanding and support of the people themselves which is essential to victory. And I am convinced that you will again give that support to leadership in these critical days.”

Birthday Flowers from May

OK, so my Birthday was in May.  Those of us that use film know that rolls sometimes aren’t finished in a timely fashion.  But these were beautiful, sent to me by my eldest brother and his wife………….Back in May.  It was my 60th Birthday, so I wanted to highlight them:

Walker Ranch Doors

I’ve done a lot of photography at Walker Ranch.  I’ve printed and displayed some too, but never focussed on the Doors…….So Let’s Go Crazy at the Ranch for this week’s Thursday Doors!

My Lomo Purple Scanning Adventure

AGH, what a fiasco.  I had this interesting image and wanted to make a print to go over my fire place mantle:

PurpleLoveliness4

You’ve seen this one before.  But, over time with the proofs from the drum scan changed my tastes after they showed me a different option, and I wanted to move in a different direction:

64819-1-12x8-Drum1_Edited4_Posted

But the Print Specialist didn’t want to work on it anymore.  My husband suggested that my order wasn’t important enough (i.e. not enough income) to make it worth their while.  I worked on the Drum scan myself a bit, but wasn’t making easy progress:

EDIT4_Drum1_Posted

You can see I have quite a bit to do before it looks like the professionally done image. Then I read this Scanning Article on EMULSIVE and decided to do a little experiment of my own. I mostly learned that drum scanning a 35 mm negative is a waste of time…….So I tried a hi-resolution (6500 dpi) scan with my Epson Perfection V700.

And Mike’s Camera Store in Boulder, Colorado, was willing to work with me.  Then the lockdown happened and although my order had been placed, I had to await the re-opening to get it.  Now placed over my Mantle:

And a smaller version in my Office, which I may end up giving away……..Both wall portraits were taken with my Mamiya-7 on a tripod using Portra 400 film.

Mike’s now has me as a permanent customer for color printing……..

Prelim Discussion of IR-Sensitive B&W Films Part II: Washi-Z ISO 400

Arcosanti_Yucca

Washi-Z 400, above with a dark red filter.  I start with that statement because for some reason I didn’t shoot the first few images with dark red.  Instead I had used an orange filter for some reason:

Piestewa_Peak

Washi-Films were never intended for use in still cameras.  They were specialty films and most were developed for recording some type of motion, including a sound version.But nowadays these specialty films are creeping into the revitalized 35 mm film market.

And finally, two images from the Tonto Natural Bridge in Arizona.  Representing some of the early orange filter exposures.

So now what?  I’ve ordered more Washi-Z 400, and because the IR effect did not seem that strong, even with the red filter.  I’m going to try it with the IR-695 filter.  Watch for new results coming soon……

The Door at Harper Lake

A local reservoir, but I couldn’t find any information on this Building.  I’m assuming it is some type of valve and pump house.

First the Door:  I was told that the Hawk Symbol was part of a Scavenger Hunt Trail…..

Frugal Film Project: March 2020

On my last roll of HP5 I found a photo to post for March:

Waddle-In

Above was my Sign offering for the March 2020 Frugal Film Project.  It just didn’t move me.  So I marked it as one of the ‘rejected’ images:

I had also considered posting one of my Valentine Roses, One Month Later………  But I’m planning a separate posting with my ‘past prime’ roses.  h dried quite well.

So more from the Roses Coming Soon………..
