Question 1

What type of ND filters are used?

Accepted Answer

Our ND filters are created using sophisticated coatings rather than dyes, for more accurate colour and exposure control.  They filter visible and infrared light equally, meaning that your camera’s native IR response is attenuated equally to its visible response.  This is more consistent than adding a simple IR cut to a dye-based ND.

Question 2

Are the filters colour neutral?

Accepted Answer

Colour neutrality across all six filters is excellent. Moving between the filter strengths no significant changes will occur.  There is a small but balanced shift moving from no filter at all to using an ND however, so in this scenario we always recommend capturing a colour chip chart in your shot to make matching simple for your colourist.

Question 3

Do I need to configure anything in the camera?

Accepted Answer

No configuration is needed in camera to use the filters.

Question 4

How well do the filters stay in place?

Accepted Answer

The rubber flange fitment works like a ratchet – easy to insert and difficult to remove. It will never shake loose, even under extreme vibration.

Question 5

How do I clean the filters?

Accepted Answer

Unlike our OLPFs, these NDs are designed for very regular handling in any environment.  They have a hard scratch-proof surface, with a water rejecting coating.  Cleaning them is trivial with any soft tissue, cloth and regular lens cleaning fluid. The glass is thin, so avoid undue pressure.

Question 6

Do I need to use the lens shims?

Accepted Answer

The back focus shims are only required if you need to maintain accurate focus marks, or hit a very specific minimum object distance.  Most stills lenses do not have sufficiently accurate markings for this to be a problem. Due to the optics involved, you will always be able to reach infinity focus, even if you don’t use the shims. Remember to remove the shim if you completely remove the ND, as that could result in an inability to find infinity focus.

Question 7

What is the flat rate shipping option?

Accepted Answer

The standard flat rate worldwide shipping we offer is via the UK Royal Mail. The International Tracked and Signed service partners with the national carrier in the delivery country for cost effective tracked delivery. In Europe 3-5 working days and worldwide 5 to 7 working days are required for delivery. We insure the packages in transit independently, and the on-time delivery success rate is over 95%.

Question 8

Can I upgrade to expedited delivery?

Accepted Answer

We are happy to ship via Fedex or similar when necessary.  Contact us via email with your order number to establish cost and shipping time.
It is cheaper in most cases for us to ship and pass the cost on directly, than to use a customer’s shipping account, due to the relative cost for export vs. import shipping, and due to insurance requirements – we insure independently to reduce shipping cost.

Question 9

Where is my package?

Accepted Answer

Please refer to your customer account and notification emails for a tracking number.  In some cases packages that cannot be delivered during working hours are held by a local delivery office, pending customer response to a letter that is posted to them. This can greatly slow down the process - please check your tracking number regularly and contact us if you have queries. Once a parcel reaches its destination country, detailed tracking is taken on by the national postal service rather than Royal Mail.

If your package has not yet shipped, please contact us by email for an estimated lead time.

Question 10

Can I use VV size filters on an S35 camera?

Accepted Answer

VV size filters will mechanically fit any DSMC2 camera body. The glass area is bigger, to accommodate the larger sensor size.

For future proofing and simplicity it is possible to use the VV size filter in an S35 camera. Numerous customers queuing for the VV upgrade have selected this option. KipperTie can provide custom self adhesive OLPF masks on request to eliminate any unexpected gate flare on S35 that may arise.

Question 11

Will it fit my camera?

Accepted Answer

Red camera bodies are either DSMC1 or DSMC2. The OLPF design is incompatible between generations.  

DSMC1 filters fit:
Epic Dragon (inc. monochrome), Scarlet Dragon.

DSMC2 filters fit:
Weapon Dragon, Scarlet-W (inc. monochrome), Epic-W, Helium S35

Red One, Red One MX, Epic MX and Scarlet MX are not supported.
DSMC1 filters are discontinued for all except false colour types.

Question 12

What do VV and S35 refer to?

Accepted Answer

Dragon and Helium sensors have a different pixel pitch, as such it is no longer possible to be explicit about sensor optical area by referring to the ‘K’ resolution.

S35 refers to a sensor size approximating 3 perf S35 film. This covers all DSMC1 and DSMC2 RED cameras, whether 5K, 6K (Dragon) or 8K (Helium) with one exception:

VV refers to a sensor size approximating Vistavision, or full frame stills film. This is presently only available in the Weapon Dragon 8K VV and VV Anamorphic cameras.

Question 13

I upgraded my camera. Do I need new filters?

Accepted Answer

If you are moving from one DSMC2 body to another, your filters remain compatible. Only the VV upgrade requires a change of OLPF size.

If you have upgraded from DSMC1 to DSMC2 your filters will need to be replaced.
There is a strong secondhand market for all RED accessories, however we can offer loyalty discounts for those wishing to trade-in and upgrade. Contact us directly for a discount code.

Question 14

Which cameras is Revolva compatible with?

Accepted Answer

Revolva is designed for any S35 sensor DSMC2 RED camera.

There is substantial compatibility with VV sensor cameras; certain lenses may vignette at full frame. DSMC2 is the current RED body style, comprising: SCARLET-W, EPIC-W, WEAPON S35 sensors: Dragon and Helium VV sensor: Dragon and Monstro.

Note:

A number of camera configurations may need a simple riser for your LCD/EVF. Not compatible - any pre DSMC2 camera, Raven.

Question 15

What accessories clash with Revolva, and what is recommended?

Accepted Answer

Red’s 7” and 4.7” touch screens require the use of a riser for installation on the top cable-less port.

We recommend the Wooden Camera tool-less LCD adapter, which adds some practicality of its own for 4.7” users too.

The DSMC2 EVF requires the same type of riser, again adding some practicality to its mounting in the process. Red’s Lemo adapters, as well as Pogo to Lemo adapters from Tilta and Wooden camera fit as function normally. No accessory or top plate can be allowed to protrude beyond the face of the camera above the lens mount, adjacent to the camera name badge.

For specific rigging queries please enquire directly prior to purchase.

Question 16

Which lenses do and don’t work, and why?

Accepted Answer

Revolva PL and PL-S are compatible with most modern PL lenses, and Revolva EF is compatible with any EF lens.

Only PL lenses which have a very deep rear element projection cause trouble. Lenses with rear projection up to ~21mm behind the flange are safe. Rear projections of ~21mm to ~23mm fit, but are in the ‘No Swap’ zone. ‘No Swap’ means the Revolva cartridge must not be swapped without removing the lens.

Note that lenses of this type tend often to be less than ideal on digital systems due to the acute angle of light striking the sensor.

To check safe lens fitment a simple tool is provided. The tool is available separately for a nominal charge, refundable against a Revolva purchase.

Question 17

Are there plans for a Nikon/Leica/other mount?

Accepted Answer

No.

Currently we intend only to make EF and PL versions.

Nikon has some electro-mechanical complications which are tough to package around Revolva’s mechanism.
Leica flange depth makes this version impossible.
Note that many unusual lenses are adaptable to EF.

Question 18

What is infrared light?

Accepted Answer

For our purposes, infrared means near-IR wavelengths. Deeper than red light, and imperceptible to our vision, but still light that can be focused by typical lenses and captured by typical CMOS sensors.  It is NOT representative of heat, and is distinct from thermal imaging which requires specialized lenses and sensors.  

In common usage, IR light of this type is used for security cameras, for satellite and agricultural imaging, and for short range optical systems like TV remotes.

Question 19

What is the difference between Full Spectrum and IR spectrum versions?

Accepted Answer

All regular OLPFS attenuate UV, IR and visible wavelengths to govern colour reproduction, making it as close as possible to a human experience of colour.

The Full Spectrum filter allows the camera sensor to see the entire range of wavelengths to which it is naturally sensitive. This means that you will have a colour image, whose colour is distorted by the presence of IR light. IR light is invisible to us, so its presence is hard to predict, but many light sources produce it.  Additionally, many surfaces, especially leaves, skin, and man-made fabrics reflect a disproportionate amount of IR, creating unexpected brightness and contrast.

The IR spectrum filter removes all visible light from the image, but allows the camera to see infrared light (720nm to 950nm) which would otherwise be filtered out.  The result is a monochromatic pink-hued and low-contrast image representing only this invisible light.  Many objects have a very unusual appearance, blue skies become dark, skin becomes almost translucent, and direct IR light sources like LEDs become amazingly powerful and bright.

Question 20

How do I create the weird colourful IR images I’ve seen?

Accepted Answer

These are achieved using the Full Spectrum filter in conjunction with any number of additional solid-colour filters on the lens.  Considerable post-production work is often applied to invert, swap and manipulate colour channels further.

Question 21

How do I create the stark, black-skied landscape images I’ve seen?

Accepted Answer

This is most easily achieved with the IR spectrum filter, but is also possible with the Full Spectrum in conjunction with a 720nm IR pass lens filter.

The resulting image needs to be desaturated, and a heavy contrast curve applied.  RED cameras are ideal for this, as the high bit-depth source allows for very aggressive grading without banding.

Question 22

Do I need special lenses?

Accepted Answer

Most lenses allow IR to pass through, however there are many possible pitfalls. Some lenses exhibit more flare, internal reflection, and iris-shaped hotspots in the image centre.
The best performance is typically found where the lenses were designed with IR film in mind. Many decades-old stills lenses have a specific IR focus dot marked on the barrel. This is a useful indication that IR performance will be good.
If IR is being used in order to capture covert or wildlife images, where light levels are typically low, care should be taken to avoid modern cine and TV lenses, which often have IR cut coatings that can reduce sensitivity to IR by as much as four stops.  For IR, old is good.

Question 23

Do I need additional filters?

Accepted Answer

For false colour imaging, it is wise to invest in additional colour and perhaps IR pass filters, to give yourself greater creative control.  Typically these are the kind of strong colour filters typically used for contrast control with black and white photography.

Question 24

How can I get sharper IR images?

Accepted Answer

The main reason for soft images in IR is split focus.  Due to the differing wavelengths, sharp focus is not possible for both visible light and IR light with the same focus position. In many cases cutting visible light completely, such as with the IR spectrum OLPF, yields much sharper images.

If using artificial IR sources, particularly LEDs, be aware that the LED wavelength can also cause this issue. 850nm is a good wavelength for shooting IR on RED, as it matches the peak of exposure response.  However, many other IR wavelengths are available, and if mixed together in a scene, can cause soft focus.

Question 25

What lighting can I use for wildlife or covert IR filming?

Accepted Answer

850nm IR LED lighting is extremely efficient for this use case. It runs happily from field-portable power, and provides significantly more exposure than equivalent powered daylight LEDs with a daylight camera.

Only a dim red glow is visible to the naked eye, and almost all wildlife vision is equally insensitive to the light as human vision.

Contact KipperTie for information on rental of field-ready IR lighting kits.

Question 26

What is Revolva? Give me the executive summary.

Accepted Answer

Solution for built-in ND on RED camera.

• Price: Starting from £1400. • Includes complete PL or EF mount for RED DSMC2 and ND 0 (clear) to 2.1 ND. • Slot in upper right side of mount receives easily swapped cartridge. • Each cartridge has four filter positions, changed by rotating filter wheel. • Always quick to return to clear filter. • No backfocus shift. • Many PL and all common EF lenses compatible. • PL and EF both have OEM circuitry and firmware support, full set of 8 filter strengths. • PL-S has no electronics and a single filter wheel. • Designed and made by KipperTie in the UK.

Question 27

How do I fit Revolva to my camera?

Accepted Answer

Fitting Procedure

• Switch off your camera. • Remove any existing lens mount using a Torx T20 tool. • Line up the mount and attach using the captive screws, always starting with the exposed screw, upper right. • Slide in a cartridge and boot the camera. • Removal is the reverse of fitting; remove the upper right exposed screw last.

Question 28

How do I change from one filter to another?

Accepted Answer

Just turn the wheel!

Ensure the locking screw us loosened and rotate the filter wheel by hand. It will snap into alignment automatically.

If you want to avoid accidental changes, simply tighten the locking screw.

Question 29

How do I change cartridge?

Accepted Answer

Just hold the filter cartridge firmly and pull it out.

A finger grip on the top surface sometimes helps. Note:

Be aware that a small number of very deep lenses can prevent the cartridge from being pulled out.
Always use the fitment check tool prior to mounting a lens, if there is any substantially long rear element.

Question 30

My back focus must be affected, surely?

Accepted Answer

No.

Revolva compensates for back focus by design. As long as you have a Revolva cartridge fitted, back focus will be correct.

Bear in mind that temperature, knocks and bumps and other factors can affect back focus for any given lens and camera. Adjusting backfocus on RED is simple, so you should collimate prior to shooting whenever absolute precision is required.

Question 31

I use EF for electronic focus, iris and stabilisation, does this still work?

Accepted Answer

Yes.

Revolva EF has full support for electronic lenses, exactly the same as Red’s own EF mount.

Question 32

I have a behemoth of a lens, how strong and stable is Revolva?

Accepted Answer

Revolva’s strength is comparable to any regular DSMC mount.

We advise you to use lens support wherever you normally would.
Typical primes and stills lenses are no issue.

The critical points are the mounting flange on the lens and the camera face.
Support is important in any case to safeguard these areas from flexing.

Question 33

Does this replace the OLPF? I have a favourite OLPF, or I don't like to change it.

Accepted Answer

No, do not remove the OLPF.

Revolva’s filtration is separate and distinct from the OLPF. As a result your preference of OLPF can be combined with any Revolva filter. No need to touch the OLPF or get near the sensor.

Question 34

How is colour affected?

Accepted Answer

Revolva is extremely colour neutral.

We always recommend testing your equipment prior to shooting. Revolva additional optics naturally result in subtle image characteristic changes.

Question 35

Do I need to configure the camera in any special way?

Accepted Answer

You may need a riser for your monitor.

However, no changes are needed in how you use your camera’s interface and controls.

Question 36

Do I need to do anything in post?

Accepted Answer

No.

No changes in post are required.

Question 37

I need iData metadata, does Revolva provide this?

Accepted Answer

Yes.

Revolva PL has the exact same support for lens data as Red’s own PL mount. Revolva PL-S does not support iData.

Question 38

How is Revolva packaged?

Accepted Answer

Revolva bundles ship with a great hard case.

Revolva comes packaged in a robust and waterproof Underwater Kinetics case with foam filling. Slots are included for multiple spare cartridges and the fitment test tool.

Question 39

Can I use more than one cartridge at a time?

Accepted Answer

No, just one.

Pro tip:
You can combine Revolva with any KipperTie OLPF, if you need ND and Diffusion for example.

Question 40

It looks like its only held on with three screws, what gives?

Accepted Answer

Nope, don't worry.

There are definitely a full complement of four.
Revolva does have an unusual cantilevered design allowing for the cartridge to be inserted.

Question 41

What's the down side?  You can tell me, we're friends...

Accepted Answer

PL has some fitment compromises, EF doesn’t.

Certain PL lenses just don’t fit. Certain lenses vignette on VV. Gate flare when not using a sunshade is potentially different from normal expectation. Certain combinations of camera accessories will obstruct fitment and require changes to your rigging.

…also, people will be jealous of your cool gear and say mean things about you in the crafty line.

Question 42

Where can I buy?

Accepted Answer

We recommend purchasing from our trusted resellers or from this site wherever possible.  Local resellers will give the fastest service and the full retail facilities you would expect. If time is not critical, or you have no local reseller we offer free worldwide 5 to 7 day shipping from our online store.

Question 43

Is a product in stock?

Accepted Answer

We are currently changing our stock indication protocol.  

Currently ‘in stock’ means that we hold all necessary parts to assemble a product. It’s a lot like ordering a car that has your own specification – it is subject to assembly and testing time, and final QC which can cause delays prior to actual shipping.  Our supply chain process has been undergoing improvements – make no mistake, we are new at this, so delivery time has not been optimal in many cases.

From 1st January 2017, ‘In stock’ on our website will mean we have pre-built, pre-packaged, QC-passed products ready for immediate shipping. 

‘Available to order’ will refer to the above process, where we hold components in stock ready to build to order.

We will continue to allow back-orders, and to offer discounted pre-orders where applicable, and as always we trust that our customers understand that lead times here are estimated only.

Question 44

Can I try before I buy, or rent instead?

Accepted Answer

We do not offer trials or rental filters, however our products are stocked by many leading RED rental houses.

In addition, our resellers are required to carry demo items for users to test.

Question 45

Are KipperTie OLPFs and filters approved by RED?

Accepted Answer

KipperTie are part of RED’s approved third party product programme.

Question 46

I have a problem, what should I do?

Accepted Answer

We are happy to offer technical support and advice directly by email.  Please get in contact, ideally quoting your order number so that we can identify your exact product.

For product warranty and replacement issues, please contact your reseller first, or KipperTie directly if purchased online.

Question 47

Where can I buy Revolva?

Accepted Answer

Online orders can be placed through this store.

Purchases are also possible through Kippertie resellers around the world.

Question 48

Question 63

Will the camera recognise the filter automatically?

Accepted Answer

DSMC 1 cameras require manual selection of OLPF type in all cases.
DSMC2 cameras will detect (on start-up only) the general type of OLPF fitted.  RED original filters will select a single fixed calibration, KipperTie’s 3rd party filters will allow the user to select their choice of colour calibration, and allow the entry of custom metadata to describe the OLPF.

Question 64

Which calibration should I select?

Accepted Answer

For diffusion filters, please select ‘Skintone Highlight’ as the calibration in the OLPF menu. 

DSMC2: Click ‘none’, change to ‘3rd party’ and then select ‘Skintone Highlight’ and add custom data if required to describe filter type

For false colour filters, please select ‘None’ or ‘Low light optimised’ as the calibration in the OLPF menu. 

DSMC2: Choose ‘none’, or change to ‘3rd party’ and then select ‘Low light optimised’ and add custom data if required to describe filter type.
