Making the Most of Cascable: Success with Shutter Robot

Cascable’s Shutter Robot is a powerful tool for automating shots that require long exposure time, multiple exposures, or both. While we’ve tried to make Shutter Robot as smart as possible, there’s still a few things that you may need to keep in mind to make sure your shot timing stays accurate and reliable.

We’ve put together some tips and tricks that’ll help you get the very best results from Shutter Robot and your camera.

All of the photos in this article (except the one of the Sony camera) were shot with Shutter Robot.

Canon and Nikon Models: Disable Live View During Shooting

In order for you to see the camera’s viewfinder image on your iOS device, a continuous stream of images needs to be sent from the camera to Cascable. Nikon and Canon cameras do this serially — while a viewfinder image is being transferred, no other command can execute until that transfer is complete. While Cascable does slow down the framerate of the viewfinder stream while Shutter Robot is running, this process can still cause timing inaccuracies with Shutter Robot’s shots.

Fortunately, all Nikon SLR and higher-end Canon models (70D, 80D, and all full frame SLR models) allow you to run them without viewfinder image streaming. This will completely stop the viewfinder stream from interfering with your shots, and will significantly reduce the battery consumption of both your camera and Cascable.

To stop the viewfinder stream, on iPad, tap the button at the left-hand side of the bottom toolbar. On iPhone, tap the button to show the expanded toolbar, then the button. Tap again to re-enable the viewfinder stream.

If you don’t have this icon, unfortunately your camera doesn’t support running without the viewfinder stream.

Olympus and Sony models stream the viewfinder image to Cascable in a way that doesn’t interfere with other operations, so this isn’t neccessary (or supported) on these cameras.

Turn Off Autofocus

If you leave autofocus enabled on your camera, it will attempt to re-acquire focus every time Shutter Robot attempts to take a shot. This can significantly increase the time it takes for the shot to be taken, which will make your shot timings inaccurate and, especially in low light, cause your shots to start backing up. Additionally, your camera might decide to focus on a different thing halfway through your shoot, or fail to focus entirely!

The best approach for avoiding this problem is to establish focus before you start, then switch your camera to manual focusing — depending on your camera, this might be done with a physical switch on your lens, on your camera body, or within Cascable itself.


Shot with an Olympus OM-D E-M1 Mark II, eight separate exposures stacked and averaged
Each exposure ISO 1600, Shutter Speed 30s, Aperture f/2.8, Focal Length 7mm (35mm equivalent: 14mm)

Noise Reduction

If you’re taking long exposures using the Bulb Timer, a camera setting you need to pay attention to is “Long Exposure Noise Reduction”. This setting has a slightly different name depending on your camera manufacturer:

  • Canon: Long exposure noise reduction / Long exp. noise reduction
  • Nikon: Long exposure NR
  • Olympus: Noise Reduction / Noise Reduct.
  • Sony: Long Exposure NR

If this setting is enabled, after taking a long exposure your camera will take a second exposure of equal length in order to try and reduce noise in the first image. While this second exposure is happening, your camera will be completely unresponsive to taking new shots.

There are two ways to avoid this, depending on your needs: You can either increase the Time Between Shots setting of the Bulb Timer to allow enough time for this to happen (make sure you leave some wiggle room — if your shot duration is 30 seconds, you might want to leave 40 seconds between shots), or you can disable the “Long Exposure Noise Reduction” setting entirely while shooting.


Shot with a Canon EOS 6D and a prerelease version of Cascable 1.0
ISO 100, Shutter Speed 12 minutes, Aperture f/8, Focal Length 25mm

Leave Enough Cycle Time Between Shots

Even if your camera has a very fast continuous shooting rate, when shooting in single shot mode (as is typical when shooting using Shutter Robot), it may not be responsive to taking new shots until the previous one has finished writing to your SD card.

You can get a gauge for this by watching your camera’s screen while you take a normal shot with Cascable. Sony models, for instance, display a big Processing box while writing to the SD card when apps like Cascable are connected.


Shot with an Olympus OM-D E-M1 Mark II
ISO 800, Shutter Speed 1/50s, Aperture f/1.2, Focal Length 25mm (35mm equivalent: 50mm)

If you don’t leave enough time between shots, your shot timing will be erratic and you may even miss shots entirely. You can reduce the time your camera needs for this process by decreasing your image size and/or getting a faster SD card.

Cascable's 2016 In Review

Cascable has had a great 2016!

Just four months ago, we released Cascable 2.0 with support for over 50 WiFi-enabled cameras, adding Nikon, Olympus, and Sony to our list of supported manufacturers. We’ve been absolutely blown away by some of the great things our users have been doing with and saying about our apps!

It's a FANTASTIC app that's well designed, full of great features and extremely useful. You're crazy if you own an Olympus camera with Wi-Fi and haven't bought this yet. Cascable is a must-have accessory.

— App Store Review

Since then, we’ve not slowed down — a month later, we released Cascable 2.1 with the Quick Proof image editor and high-fidelity RAW rendering and continued with the updates, adding new features and support for more cameras. We also introduced a new member of the family — Cascable Transfer for Mac — which, after a successful public beta, was launched last week.

We’re finishing off the year with a couple of minor updates — Cascable 2.4.1 and Cascable Transfer 1.0.1 fix a few bugs and add support for the brand new Olympus OM-D E-M1 Mark II.

We hope you have a great holiday — we’re slowing down a little to recover, but we’ll be back in full force in the new year as we start work on some major new features for the Cascable family.

Cascable Transfer for Mac Released, and New Supported Cameras for Everyone!

We’re happy to announce a new member of the Cascable family: Cascable Transfer for Mac!

Cascable Transfer copies photos from your WiFi-enabled camera to your Mac, optionally importing them directly into your Photos library or Lightroom Catalog. Just like Cascable for iOS, Cascable Transfer supports a multitude of cameras from Canon, Nikon, Olympus and Sony, and fully supports RAW files from all supported cameras.

Cascable Transfer is designed to completely integrate into your photography workflow out-of-the-box — if you use Apple’s Photos app, it will seamlessly add your images into your library without having to configure anything. If you use Lightroom, Cascable Transfer will pick up your Lightroom Catalog and copy images straight into the folder of your choice before adding the images to your catalog.

For advanced users, Cascable Transfer has powerful but friendly controls for customising how your photos are organised on-disk as they’re copied — using these controls, your photos can be organised exactly in the way you want without any extra work!

Cascable Transfer is out now as a public beta and supports all of the cameras supported by Cascable for iOS except some older Sony models that don’t allow access to their SD cards over WiFi. If your camera has a • mark in the Storage Access column in our camera compatibility chart, you’re good to go!

Cascable Transfer will cost $14.99 or your local equivalent once it comes out of public beta later in the year. However, if your purchase during the beta period, you’ll get a 50% Super Early Bird discount!

Head on over to the Cascable Transfer page to download the Public Beta and get started!

New Supported Canon Models in Cascable for iOS

Additionally, we have a quick update on Cascable for iOS: Today we released version 2.3, which adds support for the following cameras:

  • Canon EOS 7D Mark II
  • Canon EOS 5DS
  • Canon EOS 5DS R
  • Canon EOS 5D Mark IV

A few notes on these cameras:

  • Cascable Transfer supports them too!

  • The 7D Mark II, 5DS and 5DS R all require the separate Canon W-E1 WiFi Adapter, which fits into the camera’s SD slot. We’re happy to report that the performance of this adapter matches the speed of the built-in WiFi of Canon’s other cameras — something that can’t be said for external adapters from other manufacturers.

  • If you’re working at full resolution on the 5DS or the 5DS R, you may experience problems working with RAW files on older iOS hardware. You’ll still be able to copy them from your camera and export them elsewhere, but 50MP RAW files are huge, and older devices simply don’t have the RAM to reliably render them at high quality, so you may encounter difficulty with Cascable’s Quick Proof feature with these files.

Making the Most of Cascable: Some Handy Little Tips

When building Cascable, we found that a few little tweaks and touches could make a huge difference when working with the app out in the field. This post discusses a few of our favourite little tips and tricks for when you’re out and about with Cascable.

Force Touch

If your iPhone supports Force Touch, there’s a bunch of time-saving tricks that you can access just by pushing a little harder:

  • Jump straight to the section of Cascable that you’re after directly from your phone’s home screen. Force Touch Cascable’s app icon and you’re away.
  • Cascable’s shutter button can work just like the one on your real camera! Press gently to focus, Force Touch to fire the shutter.
  • If you’ve got ★PRO Photo Management (or ★PRO Full Unlock) then you can already get a hi-res full screen preview of the photos on your camera, without having to copy them to your phone first, just by tapping on the photos’ thumbnails. How about using Force Touch to peek and pop into those photos?

Live Hi-Res Shot Review

With supported cameras, Cascable can act as a wireless monitor for automatic review of shots as they’re taken by the person holding the camera.

The physical buttons and dials on your camera are usually disabled when Cascable’s connected via WiFi. However, on supported cameras1, if you disable live view from Cascable’s extended toolbar you can regain control of your camera using its physical buttons.


Disabling Live View

This can be useful in a studio scenario where a photographer is shooting with a camera freehand whilst the shots are being wirelessly reviewed as they’re taken on an iPad. If you set Photo Review’s Automatic Dismissal setting to Manually, shots will come through as they’re taken and stay on screen until the next photo is taken.

Shutter Lock

When engaged, Shutter Lock keeps the shutter pinned until you tap again. To enable Shutter Lock, first set your camera’s time/shutter value to Bulb, then tap the shutter button with two fingers.


Using Shutter Lock

This is especially useful on the cameras which support Live Bulb, like the Olympuses (Olympii?), as an evolving preview of the shot is streamed through every second or so. Great for night photography or when working with super-dark neutral density filters.

  1. Cameras which support live shot review include Canon EOS xD and xxD, and Nikon SLRs. 


Cascable 2.1 Released!

Cascable 2.0 was released a little over a month ago and we’ve been overwhelmed by the positive response it’s received from our users and the press alike, and were over the moon to receive a 4.5 star rating from PhotographyBLOG!

However, we haven’t been resting on our laurels! We’ve been listening to your feedback and are pleased to announce the release of Cascable 2.1, which adds a number of improvements to Cascable’s existing tools and a couple of new features we think you’ll love.

Greatly Improved RAW Fidelity

If you’re running iOS 10 or higher and have a modern iOS device, Cascable will render your RAW files with significantly increased quality and color depth. This looks particularly great on devices with displays that support the P3 deep color gamut — currently, the 9.7” iPad Pro and the newly-released iPhone 7 models.

This feature requires fairly modern devices — iPhone 6 or higher, iPad Air 2 or higher, or the latest 6th generation iPod touch. The reason for this limitation is that processing RAW files takes a significant amount of resources and requires a certain level of memory, CPU, and graphics power to be able to do successfully. In fact, the iPhone 6 only just made it in as we’re pushing the memory ceiling on iOS devices with 1GB of RAM!

If you have an older iOS device or are running on iOS 9, Cascable will continue to render RAW files as it did before this update.

Quick Proof

We’re really excited about this one!

The idea for Quick Proof came about when we were out and about taking photos with Cascable, and wanted to make sure that bright sky would recover nicely or there was enough detail in the shadows. We also wanted to share these photos to social media, but we typically wanted to apply a couple of adjustments to the images first, particularly with RAW files.

However, the number of apps that support RAW files properly on iOS is limited — most of them use the built-in JPEG preview when editing, so our highlights and shadows are lost before we even start. Additionally, when you share a photo to another app, you duplicate that photo when doing so — those big RAW files add up fast!

Cascable’s new Quick Proof feature solves all of these problems. Using Quick Proof, you can apply adjustments to your photos right within Cascable. Quick Proof is built on top of our new high-fidelity photo renderer, meaning you get high-quality editing of your RAW files with full deep-color support!

Since it’s built on our new high-fidelity renderer, Quick Proof (even for JPEG photos) has the same requirements as above: iOS 10 and an iPhone 6 or higher, iPad Air 2 or higher, or the latest 6th generation iPod touch.

A few notes about Quick Proof:

• Quick Proof is available to all users that have purchased either Cascable Pro: Photo Management or Cascable Pro: Full Bundle.

• Quick Proof currently supports the following adjustments: Exposure, Highlight & Shadow recovery, White Balance, Contrast, Saturation, Sharpening and Vignette.

• We don’t consider Cascable a fully-fledged image editor, so we never ever modify your photos. Quick Proof works by saving the settings you apply alongside your photos and applying them live. When you exit Quick Proof, your photo will revert back to its unedited appearance.

• When you share from within the Quick Proof editor, Cascable will generate a JPEG image with your edits ‘baked in’ for sharing to social media, exporting to another app or your computer, etc. To make your JPEGs look as great as they can, they’re saved with the Display P3 extended gamut color profile. The JPEGs should look fine even in software that doesn’t support color management, but do get in touch if you have problems.

To compare, you can check the following JPEGs. The first is a JPEG from a RAW+JPEG photo taken with one of our test cameras with absolutely no processing done to it whatsoever, and contains the standard sRGB color profile.

The second JPEG shared from Quick Proof on the RAW of that same photo, with slight bumps to exposure, contrast, saturation and a vignette. It contains the Display P3 color profile, and should look a bit warmer and brighter than the straight-from-camera JPEG.

Other New Features

We haven’t stopped there! We’ve been listening to your feedback, and have improved a few of Cascable’s existing tools:

Repeating Bulb Timer

Shutter Robot’s Bulb Timer can now be configured to repeat either a set number of times or for a set duration. This feature is great for taking a series of shots you might want to stack later. If you manage to produce some great shots with this, let us know — we’re dying to see some amazing night shots!

When working with long exposures, cameras tend to need a sort of ‘cooldown’ time between shots, particularly if they have long exposure noise reduction features enabled. With this in mind, the Bulb Timer also has a “Time Between Shots” setting, which lets you account for this.

We’ll be publishing a blog post soon packed full of tips and tricks for success with Shutter Robot!

Light Meter

With supported cameras, Cascable will switch its Exposure Compensation display to show the readout from the camera’s light meter in stops when you’re shooting in a Manual exposure mode. If the display starts flashing, your exposure settings will result in an exposure further from ‘correct’ than the display indicates.

Unfortunately, this feature isn’t supported on Sony cameras as they don’t convey their light meter readings to apps like Cascable. Sorry!

Improved Exposure Readings

If you’re shooting with iPhone in exposure modes other than Manual, you’ll now see the result of the camera’s autoexposure system in their respective displays. On both iPhone and iPad, those readouts will start flashing if your camera can’t achieve the desired exposure with the current settings.


If you see this, you've probably left your lens cap on!

Improved Photo Previewing

If you’re using a camera that supports on-body shooting while Cascable is connected (some Canon models and most Nikon models with Live View disabled, as well as some Sony models), Cascable will now recycle the Photo Review screen if it’s still visible from a previous shot. If you set Photo Review to dismiss manually, you can use Cascable as a continuously auto-updating high-res preview of your shots.

In addition, when you’re previewing photos in the Photo Management section of Cascable previews are cached for super-fast repeat previews, and you can delete photos from your camera or iOS device right from the high-res preview screen.

Bug Fixes

An update wouldn’t be complete without a pile of bug fixes. In particular:

• Cascable is now fully iOS 10 compatible.

• We fixed a problem that would cause Shutter Robot’s bracketing to not work correctly on some cameras set to the Manual auto exposure mode. This affected the EOS M3 in particular.

• We’ve greatly improved the reliability of Cascable’s camera detection. If you ever have to force close Cascable and relaunch it in order to connect to your camera, please get in touch — that should never happen again!

• And much more!


Phew, what an update — and that’s not even the whole list! You can find the full release notes for Cascable 2.1 over on our Version History page.

Right, Photokina is coming soon and we’ve heard there’ll be lots of new cameras to support — I’d better go prepare. Enjoy the freshly improved Cascable, and do get in touch with any questions, comments, or awesome photos you take!

Cascable 2.0 Released!

We’re proud to announce the release of Cascable 2.0! Version 2.0 has been a long time coming - we started the long road back in October 2015 with this tweet:

Some of the more exciting things in this release:

Increased Camera Support

By far the biggest time sink in this update was support for cameras from multiple manufacturers (Cascable 2.0 supports 50 camera models from Canon, Nikon, Olympus, and Sony). We ended up rebuilding a large portion of Cascable’s internals to allow it to gracefully deal with the fact that each manufacturer builds their network stack differently. Happily, we’ve ended up with a solution that should make it a lot easier to add further manufacturers in the future.

Night Mode

This nearly shipped with Cascable 1.0, but got cut due to time constraints in the months leading up to launch. We’re really happy with how it turned out, and several of our testers told us they now use Cascable with Night Mode enabled 100% of the time!

Better RAW Support and Improved Photo Management

Cascable 2.0 supports the RAW+JPEG workflow much better now (no more duplicates!), and the photo management workflow is also much better. Photos are arranged in groups by day, and you can filter and search through the photos you’ve copied into Cascable.

The fullscreen photo viewer has seen some love, now showing photo metdata along with a histogram, and it now allows you to zoom in to your photos at 1:1 resolution.

High-Resolution Previews

One of the more popular pieces of feedback we got from our Cascable 1.x users was that the workflow for verifying you’d successfully nailed the shot was too clumbersome - you’d need to take the photo, switch to photo management, scroll to the bottom of the list of photos, download the photo you’d just taken, then (finally) view it. We’ve made three changes in Cascable 2.0 to make this much better:

  1. Shot Preview automatically shows a preview of the shot you’ve just taken right in Cascable’s remote control. Depending on your camera, these previews aren’t quite the same resolution or quality as the full photo, but they’re lovely and fast to load and contain more than enough detail to verify focus and exposure.

  2. Photo Management shows the photos on your camera with the newest at the top. It’s a small change, but no more scrolling to the photos you’re most likely to be interested in!

  3. Photo Management also allows you to preview any photo on your camera by tapping the thumbnail or with Force Touch on compatible iPhones. The preview here is very similar to the one given in Cascable’s remote control - not quite the size or quality as the original image, but fast to load and with plenty of detail.

Free To Get Started

One of the largest barriers to entry for Cascable 1.x was the up-front cost. We understand that it’s difficult to dive in on a $25 app without being able to try it first, so with Cascable 2.0 we’ve made the base app completely free with the various “Pro” features available as an In-App Purchase. Each feature pack is $9.99, or you can buy all three in a bundle for $24.99.

All of our existing customers will receive Cascable 2.0’s Pro features free of charge. Thank you for supporting us early on!

…And Much More!

We’ve made improvements throughout the whole app - far too numerous to list here.
