Photosets User Guide

📌 In early-June, we adopted a new Version Format for App Updates.

The first number represents the Year the App Update was Released,
the second number represents the Total Number of App Review Approvals.

See Photosets' Version History (in the App Store) for reference.

-----


📌 Important Note:

Photosets v25.408 takes a Memory Footprint snapshot when entering the Camera,
& shows delta-values relative to that.

It does NOT include free() DE-allocations.

That's next ! ...

In the meantime, you can still use the "Memory Footprint Monitor"
to help you figure-out how Photosets works.

Monitor it both with & without the Prime the Pump setting enabled.

And for clarity, the benefit of Prime the Pump is Higher-Precision Timing (Capture).

But it's NOT needed in ALL cases.

Usually ONLY when you're first starting-up Photosets' Camera
AFTER a Fresh Launch or AFTER its been Idle for awhile.

📌 A few comments regarding v25.402 :

1.) Object Detection

This feature was first-added in v25.401, but was NOT enabled for End Users in that update.

In v25.402, we've enabled a 1st cut of "the Framework" for it, so that potential Investors & Corp Partners, as well as (Premium) End Users, can envision it.

And BTW, it's a General Purpose feature that we're currently using for Drone Detection.

Also, as stated in the What's New for v25.402 :

Note that in this mode, the Camera Shutter operates in an Auto mode.

Note also that ONLY the 15P, 15PM, 16P, & 16PM are currently supported.

 2.) 10-bit 4K Capture + 10-bit ProRes 422HQ Video Maker

Photosets has included support for this since Oct 24, 2024.

We're moving it to the Premium sub.

 3.) AirDrop with HSPX

We've RE-enabled this in preparation for release of our macOS-based HSPX Decoder.

As a reminder, HSPX simply stands for High Speed Photoset Container file format.

It's simply a convenient way "for transferring" sets of photos via AirDrop.

As well as "for storing" sets of photos.

-----


📌 Hot Tip #1:

After installing Photosets, open the Settings app, Tap your name / iCloud / Manage Account Storage / Backups / (select) your iPhone OR iPad, Turn Off Photosets & Confirm.

That will prevent iOS (& Apple servers) from backing-up Photosets to your iCloud storage.


📌 Hot Tip #2:

ALL of the Photo & Video files inside Photosets
are (also) accessible via your native iOS Files app !


📌 Hot Tip #3:

The Home View's Vertical ScrollView is presented ONLY if there are ONE OR MORE photo sets stored in the app.

It is scrollable whenever there are TWO OR MORE photo sets stored in the app.

If you tap the photo displayed in the Veritical ScrollView, you'll transition into the 1st view of the Editor.

Tap it again to transition into the 2nd view of the Editor, OR swipe to the right to transition back to the Home view.

The 1st view of the Editor is where you select the Editor's playback speed.

The 2nd view is a Photo Set-based Media Player + Trim & Fav Tag Editor.

-----


Section 1. The BIG Picture Perspective

Photosets consists of the following Major Features:

● Home View Photo Set-based Navigator

Photosets always starts-up in the Home View.

From there you can Navigate thru your Photo Sets, as well as to other sections of the app.

● Burst Photo Capture Engine

The Camera Settings dialog is presented just-before transitioning into the Camera.

● Photo Set-based Editor

Here you can Trim the Begin and/or End of your Photo Sets, as well as Favorite-tag up-to "5" Photos per Photo Set.

● 8-bit 420 60-scene Video Maker

● 10-bit 422 single-scene Video Maker

(1) 4K Capture is Image Stabilized.

8-bit 420 4K capture supports JPEG & HEIC.

10-bit 422 capture currently ONLY supports Lossless LZ4 "data" compression.

(2) 12 Mpx Capture is NOT Image Stabilized.

Capture Rate is Fixed at 30 fps.

(3) 8-bit Videos crafted by the app's 8-bit Video Maker
may optionally include concurrently captured Audio data.

(4) In a near-future update, 10-bit Videos crafted by the app's 10-bit Video Maker
will ALWAYS include per-Scene Dynamic Metadata.

This is something we've recently accounced.

📌 Our First Shortcut for Photosets

Our plan is to release this concurrently with the release of Photosets v10.31

And BTW, we're Field Testing this here in San Diego with our Shoreline Female Dynamic Photo Modeling Application/Use-Case, where the iPhone running Photosets is attached to a Tripod via an Adapter.

With this approach, once we execute Step #9, Start Photosets, it's Free Running until Completed.

i.e., until the multi-scene Video has been crafted.

Consider this simple example that captures Burst Photos in 4K30 via the Back Wide Camera:

"Shortcut Photosets + Capture 10 Sets of Max + with Audio + Delete Photos +
Make 10-scene Video + ... Start Photosets".

Including the "+" is optional; it works with OR without it.

The operation automatically starts at "Start Photosets".

The "..." in the example above is added to illustrate OR promote delay.

i.e., don't issue the "Start Photosets" command until you are Ready for Capture.

Once started, if you need to Kill the Sequence of Operations before it completes, simply issue the command "Stop Photosets".

📌 Hot Tip #3:

The Apple Log Transfer Function:

Open the Settings app, Tap Camera / Formats, & read the description for ProRAW.

i.e., the description that starts with "ProRAW is a 10-bit file ...".

Next, tap ProRes Encoding, & read the description below the three options.

Make sure the Apple ProRes switch is set to ON.

The key part of the description is:

Log will appear flat and gray before processing adjustments are made.

Note that Apple uses Apple Log for video recording with ProRes encoding.

And that Photosets uses Apple Log for high-precision timing burst photo capture
with NO encoding during capture.

-----


📌 (Under Development) RGB3x Depth Map support:

The v2 RGB3x Capture "Depth Map" header field can be ANY integer value between "1" and "4," representing what the photo resolution width & height are divided by.

E.g., if "1," then the Depth Map Res is equal to the Photo Res.

if "2," then the Depth Map Res is 1/4 of the Photo Res.

If "3," then the Depth Map Res is 1/6 of the Photo Res.

If "4," then the Depth Map Res is 1/8 of the Photo Res.

Set to "0" to specify that there is NO Depth Map.

The Depth Map header field is located at [19:15] in the RGB3x 4B header.

And BTW, Depth Map datapoints are represented as 16-bit unsigned integers.

First, some Important Notes:

● Photosets runs on both your iPhone & on your Apple Silicon Mac !

● Capture on your iPhone, "AirDrop by Date" (with HSPX enabled) to your Mac, & then craft Short-Form, multi-scene Videos, with up-to "60" Video Scenes, on your Mac !

● You'll need to use our FREE companion macOS app for Photosets, Photosets TV/Studio, available ONLY via this website, to make it work.

● Photosets TV/Studio supports & offers custom App Group-based content sharing !

There are two main benefits:

● Enables you to Offload your Burst Photo Sets & their companion Audio data from your iPhone.

i.e., after "AirDrop by Date" (with HSPX enabled), you can use app's "Delete by Date" feature (& using the same date) to delete your photo sets & their companion Audio data.

● When the Video Maker is run on a Mac, it becomes a "Multi-User" solution.

i.e., you can craft Videos from content captured by multiple Users.

When running Photosets on an Apple Silicon Mac:

● You can now scroll thru your Burst Photo Sets via the Mechanical Keyboard's "Up Arrow" & "Down Arrow" keys !

● Specifically, there are two places in the app where we're added this new support:

● 1.) The Home View's "Photo Set Navigator".

● This is where you vertically scroll thru your burst photo sets.

● 2.) The Video Maker's "Photo Set Navigator".

● This is where you "select the order" of the Video Scenes that are used to make a Video.

● Please note that you MUST place the "curser" (from either the Trackpad OR the Mouse) above the relevant "vertical" UIScrollView implementation for it to take affect.

● That's because the implementation uses two UIHoverGestureRecognizers, one for the Home View's "Set Navigator" & one for the Video Maker's "Set Navigator", as a Safety Net.

-----


If you have an Apple Silicon Mac

● Photosets on an iPhone for Burst Photo capture !

● Photosets on an Apple Silicon Mac for crafting "multi-User" multi-scene Videos !

● Photosets TV/Studio in-between providing custom App Group-based content sharing !

Here's a quick summary of what's involved:

i.) With Photosets running on your iPhone:

1.) Via the app's In App Settings, enable concurrent Audio capture.

2.) Using the app's Camera, capture Burst Photo Sets & their companion Audio data.

3.) Via the app's In App Settings, set the "AirDrop with HSPX" switch to ON.

4.) Using the app's "AirDrop by Date" feature, transfer your Burst Photo Sets & their companion, concurrently captured Audio data to your Apple Silicon Mac.

Using AirDrop by Date (with HSPX enabled) ensures that companion, concurrently captured Audio data is automatically transferred during the AirDrop operation.

ii.) After you Download & Install both Photosets & our macOS app, Photosets TV/Studio, to your Apple Silicon Mac:

(Please note, Photosets is available via the Mac App Store, our macOS app Photosets TV/Studio is available ONLY via our website.)

5.) Launch Photosets TV/Studio on your Apple Silicon Mac, & then use it to move the .hspx files in your ~/Downloads folder to the App Group Rx container folder shared with Photosets.

The .hspx files are your "Inputs" to Photosets.

6.) Launch Photosets on your Apple Silicon Mac.

This step will trigger Photosets to extract the contents of the .hspx files.

7.) Using Photosets' multi-scene Video Maker, craft your Videos.

Your videos are your "Outputs" from Photosets.

To access them, you'll need to use Photosets TV/Studio to move them from the App Group Tx container folder shared with Photosets, to your ~/Downloads folder.

-----


Photosets has "two" A/V-enabled Burst Video Makers:

1.) Multi-Scene Video Maker

(accessible via the Compose button on the bottom toolbar on the Home View)

2.) On-the-Fly Video Maker

(enabled via the bottom Segment in the Camera Settings Dialog for Tier 1 iPhones & iPads)


● The (shared) Video Maker A/V Sync function is accurate to +- 83.33 us "on a per-Video Scene basis" !

● Video files start with "PsTv_," where PsTv stands for "Photosets TV".
