Pro photographers around the world love OptiCull

Felipe . @felipebocafoto . 🇧🇷 Brazil

It's VERY fast!

"I used Photo Mechanic previously, but your app is much better. I use the scenes for the formal photos on the cake table at the wedding, which are very similar, so the scenes mode helps a lot."

Chema . @chema_photo . 🇪🇸 Spain

Get back a lot of your time!!!

"This is game changer honestly. Super fast preview and culling of your photos. Also improving it every time more and more!"

Lightning fast RAW previews and AI analysis

Never wait for previews or closeups to show up while reviewing your shoot.

Start reviewing instantly while OptiCull analyzes photos at the speed of 1000 photos under a minute.

Video shows the lightning speed of OptiCull in real time on M1 MacBook Air. It gives similar viewing speeds even on Late 2013 Macbook Pro with 8GB RAM.

Let's create a scene

Groups duplicates into scenes in real-time

Grouping duplicates makes it easy to compare them side-by-side and select a diverse set of final photos.

You can adjust grouping preferences to group more photos together and reduce number of keepers.

Just like good old polaroid days

Side-by-side compare and Synced Zoom modes

Just select multiple photos or scenes to compare them side-by-side utilizing your screen real-estate.

Use synced zoom modes to compare the same face, all faces or same regions in multiple photos at once.

Navigate different faces in sync when in face zoom mode

One-take per scene

Scene layout modes for faster review

Use layout modes like Scene Survey mode to sift through scenes instead of photos one by one.

It previews all photos in selected scene(s) by default.

Just pan and zoom on one photo to compare different regions in one go, without the need to go back and forth.

Rushed days? no sweat..

Magi-Cull and Auto-Rate, personalized and instant

Rejects photos with blurry and blinking subjects based on your preference.

Selects best diversified keepers from each scene.

Set ratings you use for keepers, duplicates and rejects, OptiCull will automatically assign those.

You are always in control using assessment overrides while reviewing magi-cull results.

AI doesn't know everything... just yet!

Warnings for quick review

Focus and Eye assessments are highlighted under each face for quick check without zooming in.

Magi-Cull assigns blur and blink warnings to keepers without better alternatives.

It also flags photos without people that it could not assess, for you to review.

Frequently Asked Questions

What is culling in photography?

In photography, culling is the process of selecting final deliverable photos from all the photos taken during a photoshoot. Generally, culling is done before editing the photos so that only the photos that need to be delivered are edited, and editing effort is not wasted.

Why should I use photo culling software?

Good photo editing software is generally very slow when showing previews and does not usually have built-in smart features for culling. When you need to go through a ton of photos to select several hundred, those slow previews and lack of intelligent features will significantly slow you down. So, it makes sense to use purpose-built software for photo culling to save time drastically.

Why should I use AI photo culling software? Photo mechanic is fast enough.

Firstly, if you consider Photo Mechanic fast enough, please give OptiCull a try. You'll be surprised. Even with fast photo culling software, you still have to zoom in to check for focus and blinks, and reject low-quality photos. Moreover, you have to go back and forth while comparing duplicates to select a diverse set of final photos. AI photo culling software like OptiCull automatically tags low-quality photos with bad focus or blinks, groups duplicates together in scenes to compare side-by-side, and selects the best photos from each scene in automated mode. This drastically reduces your culling time. And even if you choose to review the results or opt for manual culling, you can sift through scenes instead of going through each photo one by one.

Why should I use OptiCull? How is it different from other photo culling softwares?

OptiCull is the fastest photo culling software, both in terms of fastest RAW previews, face close-ups, and in terms of how fast you can review your shoot. It supports both automated and manual culling workflows. OptiCull magicully sorts duplicates into scenes, rejects blurry and blinking photos, and selects the best diversified keepers automatically based on your culling preferences. Even for manual culling, you can sift through duplicate scenes using innovative side-by-side comparison and zoom modes. For automated culling, all culling preferences are applied in real-time, you do not need to restart culling to see results. You can preview any scene to see the effects of culling preferences live to decide faster. Also, OptiCull will be the only option available on the Apple AppStore, which goes through rigorous Apple review for your security and privacy.

How does OptiCull use my photos?

All your photos remain on your local machine at all times. All AI processing happens locally on the device. OptiCull does not need to and does not send your photos to any external servers. We deeply care for your privacy, so rest assured. DopeAI also comply with GDPR, please read our privacy policy to learn more.

What camera models are supported?

OptiCull supports photos in RAW format that are supported by the host macOS version. For details, please check the Apple documentation for RAW support on your macOS version. Ideally, RAW photos that are viewable in Finder and Apple Preview app should be supported by OptiCull. Additionally, OptiCull supports JPG and RAW+JPG formats. Although unsupported RAW files are not officially supported, they may still work if they have large enough built-in JPG previews. As a short-term solution for working with macOS unsupported cameras, you can either turn on 1:1 inbuilt previews if your camera supports it, shoot in RAW+JPG, or convert them to DNG with 1:1 previews before importing.

What are the minimum system requirements to run OptiCull?

OptiCull can run on any Mac running macOS 11.0 or later. To test beta builds, you will need macOS 12.0 as Apple TestFlight requires macOS 12.0 to run. OptiCull is super fast and less resource-demanding, so it will run smoothly even on a Mac with 8GB RAM.

What all editing apps OptiCull works with?

OptiCull can ship selected photos directly to editing apps like Lightroom Classic, Lightroom CC, Capture One, Apple Photos and any other macOS app following standard file import guidelines from Apple.

Is Windows version planned?

We regret to inform you that there are no plans for a Windows version at this time. Our current priority is to provide an exceptional user experience while adhering to the platform guidelines for macOS first.

Already purchased CullAi, how do I avail free upgrade to OptiCull Pro?

If you bought CullAi Standard edition before June 7th, 2023, you are eligible to get a free upgrade to OptiCull Pro. Open the latest version of CullAi while connected to the internet, then open the latest version of OptiCull to enjoy OptiCull Pro. If you don't get upgraded, try restoring your original purchases in CullAi first.

Sign in with Apple not working?

When you sign in with Apple on OptiCull, Apple displays the Apple ID login dialog. If you have already signed in to your Mac with your Apple ID, it just needs to confirm if you want to continue with that account. For the confirmation, it either uses Face ID, Touch ID, or your device passcode (in case Touch ID is not available or not configured). Users often try their Apple ID password instead of the system passcode on this prompt, resulting in sign-in failure.

Once you click the Sign in with Apple button, what you see is Apple's own sign-in flow, and OptiCull doesn't receive any of your credentials. You can find more information about this in "Use Sign in with Apple" section of the Apple's sign in guide.

Why Sign in is required?

We actually did not have Sign in to start with. But for some particular use cases this is the only recommended way by apple. Like Sharing In App Purchases in two or more apps when grand-fathering purchase in one app to another app.

We needed this while giving free upgrade to our existing CullAi customers. Considering we will be introducing more products sharing In App Purchases, Sign in is made mandatory.

You can always Sign in with Apple and keep your name and email private. But we totally respect your decision in case you decide not to Sign in.
