Audio-Visual (AV) presentations

Page in development

Why make an AV?

Audiovisual presentation can add extra dimensions to your creativity. In standard photography you pick your crème de la crème image that has to convey its message in splendid, silent isolation. With an AV you can sequence images to support a narrative. You can add movement to help guide the viewer’s eye across the image. You can add sound to control the viewer’s mood and emotional attachment, or to evoke memories and thoughts that support your narrative. What is more, you can do this with only a little effort, and even using software you probably already have (though specialist software – free or commercial – may make some tasks easier).

I first came across AV presentations back in 1960, when Olegas Truchanas and Ralph Hope-Johnstone presented their audio-visual slideshows bringing the stunning beauty of Lake Pedder (the real Lake Pedder, not the impoundment we now have) to the public.They presented time and time again over almost 3 years to packed audiences at the Hobart Town Hall. They didn’t prevent the hydro scheme that flooded Lake Pedder, but they helped found an environment movement that has only snowballed over time.

Back then the technology was quite cumbersome and out of reach for most. Their system used with two commercial grade slide projectors on custom built stands to allow them to be carefully aligned to match on the screen, and a box of electronic wizardry that allowed them to do synchronised fade transitions between the two slide projectors, and coupled with an sound system playing the background audio. Now, with computers and digital projection it is so much easier. Making your own AV presentations is in easy reach.

Tell a story

If you are going to make an AV, it’s a good idea to think about what you want to achieve. Just putting in a jumble of disconnected images is much less powerful than a carefully curated set of images that have coherence, that tell a story. So think about what you want to convey. Hunt for images that will help build the narrative. They don’t all need to be world-class – the storyline is the important thing. And think about what audio support you will need. Choose audio that complements rather than clashes with your narrative.

Software features

Transitions

Choose transitions – the period as the images change – carefully. Simple is often best. Cross fades generally work well, with fade to/from black good as “paragraph breaks” between distinct sections of a slideshow. The transitions should be sympathetic to the narrative you are building. A brutalist industrial theme might benefit from quick transitions; a slideshow of mothers and newborns might benefit from slow transitions. Too many different sorts of transition may make your audience focus more on the transitions than on the images or the narrative.

Timing

Show each image for long enough for the viewer to see and understand the image. Choose timing to graphically complement your images and narrative. It is often easiest to use a set timing – say 5 seconds, for each image, but that may not be optimal. Some parts of the narrative might warrant a quick series of images; other parts might suit a more leisurely timing. Think about the timing in concert with the audio track. A slow, lyrical passage of music may not fit with a fast and frenzied burst of images.

Music

Music has extraordinary power. It captures the emotions. It evokes memories. It is a valuable part of the AV. Even if you have spoken narration accompanying your images, blending the spoken word with complementary music can be very powerful. See more under the Audio heading.

Ken Burns effect (Pan and zoom)

This effect is achieved by panning and zooming over static photos to give a sense of dynamism. Ken Burns made the technique famous through his use in his fabulous documentaries, but the approach was used before him (look up rostrum camera effect). You can use the effect just for a sense of motion, or, by carefully setting the path of the pan/zoom, and any pauses in movement, you can direct the viewer’s attention to a particular part of an image (or maybe several parts). This is a powerful technique used well. Note that if you pan or zoom too fast the end result may be jerky, unsatisfactory video output, or your viewers may not be able to focus as things whizz past.

Export to video

Most software gives options for output in various resolutions, frame rates, compression rates and file formats. This is an incredibly complex area. If you need more, search the web for assistance, or ask a friend who is skilled in the area (if you have such a friend).

Images / Video clips

You needn’t be confined to photographic images. You can blend in video clips too. These may be great for catching things that static photos may not convey in the same way. Think waterfalls, windsurfers, racing cars, or children playing, and so on.

Audio

The audio is a vital component. It can narrate the story. It can set the mood. It can punctuate the presentation.

Narration can be challenging. Speak slowly and clearly. Record in a quiet place to avoid other sounds. Think about the acoustics of the place – is it resonant (may work if your subject is about cathedrals etc, but generally not the best); are there echos? Have a script to read so you don’t stumble on your words. Do it in bits and combine the audio segments later – easier then to synchronise the narration with the flow of images

Natural/ambient sounds – appropriate to the subject. Bush sounds for bushland scenes; steam train noises for that steam train adventure… Even simple phone recordings can be effective, though with more sophisticated recording equipment you will have greater success. Directional microphones can reduce unwanted background noises; fuzzy covers on microphones cut out wind noise etc. Try to avoid extraneous sounds. That beautiful birdsong audio clip will be less effective if there is background traffic noise, for example..

Music. Huge diversity of music. Pay attention to copyright issues if you intend to show the AV beyond private settings. There are lots of resources for a great diversity of music that is available under Creative Commons and similar licenses that you can generally use so long as you appropriately cite the source. https://creativecommons.org/about/program-areas/arts-culture/arts-culture-resources/legalmusicforvideos/

Software – Free

Here are some of the available software – this is not an exhaustive list. I have tried some of these, but not all. The order of presentation here is in arbitrary order. Since they are free, you can try and see which suit your needs without any expense.

4K Slideshow Maker https://www.4kdownload.com/products/product-slideshowmaker Create slideshows with music, different effects, and presets with a simple user interface.

PhotoFilmStrip (https://www.photofilmstrip.org/en/) PhotoFilmStrip is a simple tool that lets you create videos with your photos without any prior video editing knowledge. You can arrange your images along a timeline, with customisable durations and transitions. Pan and zoom effects are simply handled. Audio is a bit primitive – you can add a single audio-track (you will have to use a program like audacity if you want to combine audio tracks), and there is no audio-line along which you can synchronise images and transitions. The program provides output in various formats and resolutions.

NCH PhotoStage https://www.nchsoftware.com/slideshow/index.html This is a reasonably sophisticated application that is available for free for non-commercial use. You can drag and drop your media into the program, arrange images along a timeline, adjust durations and transitions, animate with pan and zoom and so on. On the audio track you can set fades and other simple edits. Output to a range of formats and qualities of video is available.

Shotcut https://www.shotcut.org/ An amazing multi-track video editor. Very steep learning curve, but incredibly powerful. Similar to Adobe Premier but without the price tag. Although designed to edit videos, it handles slideshows easily, and has a wealth of features and filters to dynamically modify the images. If you are planning on doing a lot of slideshows, this program is definitely worth the effort to learn. There are extensive tutorials and learning resources on the shotcut website. And here is a quick overview of shotcut for creating slideshows: https://www.organizingphotos.net/video-slideshow-tutorial-shotcut/

Slideshow creator https://sourceforge.net/projects/slcreator/ Slideshow creator is a GUI to create, modify and preview jpg (jpeg) images slideshows to be later finalized with dvd-slideshow. Effects like crop, kenburns and scroll etc.

Exposure X6

Overview

Image from https://www.lifeafterphotoshop.com/exposure-x6-review/

I haven’t used Exposure hands-on so the following comments are based on the Exposure website documentation (there is an extensive set of tutorials and videos) and reviews I found on the web. Exposure X6 is very similar to Lightroom in its user interface. It provides file management/Digital Asset Management tools including metadata editing, virtual copies and virtual collections. It has a comprehensive RAW editing workflow with non-destructive editing pathways (similar to LR). Unlike LR it supports layered images with blend modes, masks, opacity etc. so you can make composite images, or apply filters to layer copies for more flexible editing. The user interface is customisable so you can move or hide different editing panels to suit your personal workflow. You can also use Exposure X6 as a plugin to Lightroom and Photoshop.

Note that Exposure X7 is “Coming soon” at the time I write this (august 2021), which they tout to contain new masking tools, new workspaces and improved image quality.

Capture One

Overview

Capture One started life as software to support Phase One’s high-end digital cameras, in particular in tethered image capture situations, but is now available for most makes. It is a superb professional Raw image processor. It is feature rich, with a layered image processing model. It has image management/cataloging functions, though not as good as Lightroom’s. One comparison of Catpure One and Lightroom is HERE and reviews are HERE and HERE. Capture One is available on a monthly subscription model and is more expensive than LR/PS, but there are cheaper or even free options if you use Sony or Fujifilm cameras.Fujifilm cameras.

Photopea – a free photoshop-like editor

Use it at https://www.photopea.com/ .

This is an amazing project from a talented Czech Programer Ivan Kutskir. It comprises over 100,000 lines of code! This is an online program that you can run in your browser, with a photoshop-like interface with all the things you would expect. It doesn’t have all the bells and whistles. It works with some RAW formats though the raw processing is fairly basic – you get basic exposure adjustments then it converts to a PSD file that you can edit. However if you want, you could always use one of the more capable RAW converters (RawTherapee, DarkTable, or even Adobe Camera Raw (yes you can download that for free)). It features layers, blending modes, lots of filters, selection tools…. All for free (well almost. You “pay” by having a set of adverts flashing on the right hand side of the page – there is a paid option that removes the adverts).

If you use Chrome browser (or similar) you can “install” Photopea as an App so you can run it entirely from your computer without an internet connection. (I guess if you then turn off your internet, you can edit your photos without adverts popping up).

Here is one person’s review https://fixthephoto.com/photopea-review.html and another https://irvkrick.com/photopea-review-a-free-photoshop-alternative-that-works-in-your-browser/

ON1 Photo Raw

Overview

ON1 Photo RAW is a relative newcomer to the photo editing arena (currently designated ON1 Photo RAW 2021.5), but looks to be feature filled. It includes Digital asset management and a non-destructive, layered editing paradigm, incorporating many features of photoshop as well as Lightroom. It comes with either a one-off license or a subscription model that allows you continued updates as the software develops. They offer a 14 day free trial.

ON1 file catalog screen

According to their website, ON1 can import Lightroom settings from existing LR catalogs (at least this is scheduled for the October 2021 release). It has photo-retouching tools, cloning, healing, removing blemishes, noise reduction, content aware fill etc. It handles HDR, focus stacking and panoramas. It uses some AI approaches to aspects of its image processing. It can also operate as a plugin for Adobe, Affinity and Corel applications.

On1 edit screen

On1 has a few specialised features. Notable is an AI powered portrait editing mode that looks to be quite powerful. It automatically identifies features like lips, eyes, eyebrows etc and provides controls to adjust their appearance. You can also modify the shapes and sizes of the face or face parts. If you do lots of portraiture it is definitely worth a look.

Darktable

darktable is an open source photography workflow application and raw developer. A virtual lighttable and darkroom for photographers. It manages your digital negatives in a database, lets you view them through a zoomable lighttable and enables you to develop raw images and enhance them.

https://www.darktable.org/

Darktable is a powerful program with a wealth of features. Rather than re-inventing the wheel with a detailed analysis, I’ll give a quick overview of some of the main features and leave you to check out the reviews and comments section below.

Darktable has powerful features for image organisation and digital asset management. You can star-rate images, add keyword tags, edit metadata and so on. It is a powerful RAW image processor with a non-destructive workflow. Edits are saved and you can save the edit lists as xmp files with the original image if you wish. It supports a powerful array of processing filters, and can apply effects locally with a variety of mask creation tools. It has a mapping module that allows you to make use of the geolocation data in files. You can even control your tethered camera using Darktable. The couple of screenshots below give you a feel for the workspace. To my mind it looks quite similar to Lightroom’s.

Darktable’s Lighttable workspace where you can organise images, sort, select, rate, tag, edit metadata and so on.

DigiKam

DigiKam is a free, open-source package for Linux, windows and macOS. It has strong digital asset management and a comprehensive processing workflow. It has powerful RAW file editing and a non-destructive workflow (edits are saved in a database). It supports a huge range of file formats. There is extensive documentation at the DigiKam website. Below are some screen shots to give you a feel for the program.

Some links to reviews are at the bottom (not all are for the latest version). My impression is that this free program provides a lot of power. It isn’t a slick or as fast as Lightroom, but it offers a huge array of features, notably in digital asset management (cataloging, metadata editing, organising, searching etc) that is lacking in most image processing software. And it is free, so costs nothing to try it out.

DigiKam’s main screen. Tabs at the left allow you to view the folder structure, ratings, keywords/tags, a timeline, advanced search functions, image similarity (great for winnowing duplicates or near duplicates), maps/geolocation, and people indexing (it can search images for faces and if you give names to faces, it will try to find similar faces in other photos, allowing you to search for specific people, once you have identified that person in photos).

The image editor window gives access to a wide range of editing tools. The tabs at the right give access to image properties, metadata, a map, captions and tools (see below).

The tools tab gives access to a lot of functionality including links to the image editor, tag manager, batch manager, a light table (good for sorting images, comparing images side by side, rating, tagging etc). Post processing tools include image stacking (HDR, focus stack), generation of calendars, web galleries etc. Export tools allow you to export to local storage or a range of online systems. You can also import images from your SmugMug or Google galleries, or from a scanner.

The making of an intentionally blurred image (VIcki Moritz)

So you spent years learning how to shoot images in focus? Just for a change here is how to make an intentional blurred image such as the one below

Source images- demonstrating you can make something out of not much!

An outline of the steps taken:

  1. First select an image (or images) that you think will work. A wide angle image with a point of
    interest you can reintroduce in a masking step is a good start
  2. Perform basic black/white point adjustments and ensure the buildings are straight (lens
    correction)
  3. This technique uses photoshop- the first step selected the man from a wet day in Melbourne
    and pasted and positioned him in the walkway image taken at a club outing to South Wharf.
    Remember to include reflections or shadows if you have them in the original image. In the
    case of the man it was a reflection
  4. Duplicate the layer that now contains the man and background and convert it to a smart
    object (right click on the layer- convert to smart object). This ensures you can still see the
    settings you use and can make alterations
  5. To create the blur I used filter/blur/motion blur. The setting was 1267 pixels at 90O
  6. I then added a mask to the layer and masked out the effect in the foreground as I wanted
    the image to be grounded
  7. I then duplicated the layer in step 4 again (before blur), added it to the top of the layer stack
    and added a black mask to bring back the blurred layer. I then painted in white on the mask
    to bring back areas that I didn’t want to see blurred eg the man and the railing leading into
    the image
  8. Final step was to convert to B&W using Nik software and darken areas on the edges

Enjoy having a go at this
Vicki!
