Lightroom: Slideshow: Ability to increase the slide duration to longer than 20 seconds

I need to create a very simple slideshow, to play slides in a random order and the ability to play them anywhere from 1 minute each to 5 or 10 minutes each. I use it for figure quick sketch practice. It's something artists do a lot of, and I used to do it all the time with iPhoto and Aperture. I'm so disappointed that there's no way to play a slide for longer than 20 seconds, and can't understand why there even needs to be a limit. So then I tried the manual option, thinking I could just set a timer and advance the slide manually, but this way it plays the slides in order, which doesn't work at all for this purpose. I set up a dedicated library for the pose slides, spent all day sorting and rating them into a collection, and now I can't use it.

What would you want the maximum single slide duration be?

Gosh, thanks for getting back to me about this. Usually, Quick Sketch starts at about 2 min per pose, for about 20 minutes, then we do 3 or 5 minute poses for another 20 minutes. After that it can go up to anywhere between 5 min to 20 minutes per pose, but being able to choose something in the 1 minute to 5 minute range per slide would be great. The slideshow needs to be in random order, also. This is important so you're not always starting out with the same few poses and never getting to others. Thanks so much. No fancy effects necessary, except a simple dissolve between slides.

What mechanism are you using to play the slideshow?  Are you exporting the slidehow to video and making a DVD or playing in a Mac or PC's movie player, or are you using LR to play the slides?  Are the slides for each individual sketcher's computer or on a classroom screen from a projector or how is the slideshow being played and used if you could make the slide delay in minutes not seconds?

A slideshow that plays as a video cannot be differently random from one play to the next.

A slideshow that is a program running on a computer that points to a folder of image can play things in a different order but the program that is doing the slideshow is compiled for a particular type of computer.

I don't need anything fancy at all. No videos, projectors, dvds. I just want a random assortment of the pictures I already have in my Lightroom catalog (hundreds of slides) to show up within Lightroom on my 27" Mac screen long enough for me and maybe one other person to draw a different random selection each day. For drawing practice. It should be just a static picture - no zooming or panning or Ken Burns effect.  I want to play them within Lightroom (using the Slideshow module I guess, unless you have another way I don't know about). I don't want to have to export copies of my images in different sets to Premiere or Final Cut and make elaborate videos, even though I have all that stuff and know how to do that. It's just way more work than it needs to be. I don't need a DVD of it or to save it. I don't need it to play music or display any text. I don't even need to save the slideshow, if Lightroom will just let me choose the duration and display the pictures randomly, long enough to draw, so I can have a different set of slides each time.

In figure quick sketch a live model changes poses every 2 minutes or 3 minutes or 1 minute or whatever, and you start a new drawing each time, never the same pose.  I used to be able to practice at home by sitting down in front of my computer with iPhoto, pick an album, set a duration of 1 min or 3 min or 5 mins per slide, and a random selection of slides would show up long enough for me to draw (using traditional drawing board, paper and pencils). You never get through the whole collection. Just a random selection of 20 to 50 or so each session.

In Lightroom, I made a smart collection of some of my photos and tried to make a slideshow of it - just play it on the screen so I can draw. I can't get them to play for longer than 20 seconds, and if I try it on manual, it won't play in random order. Maybe there's a way outside of the slideshow module I haven't figured out.

It would also be incredible if I could get them to play in the Lightroom app on Apple TV, but I would be satisfied to just get it on my computer without the need to export a separate file every time. 

Thanks for your interest.

For random playback, go to Lightroom's slideshow module. Under the "Playback" settings panel, check "Random Order".

Now a workaround for setting a slide duration that is longer than 20 secs allowed by the UI. 

1. Update the slideshow settings the way that you wanted (such as "Random Order")
2. On the left hand side panel, click on the "+" sign to create a custom slideshow template based on the current settings. Name it as "abc".
3. Right click (or Ctrl+click on Mac) on the newly named custom template, invoke "Show in Finder"/"Show in Explorer" from the contextual menu,
4. Now edit the "abc.lrtemplate" in a text editor, search for the line that contains "speed = ###". Replace the "###" with whatever the number of seconds you want. 5 minutes would be 300. Save the file with your changes. Restart Lr.

Now apply this new "abc" custom slideshow template when you want to play the slideshow in this special mode when doing your work. You notice that the slide duration is now set to 300 secs.

Hope this helps.
