Digital projectors? bit OT
I do talks for garden clubs but my slide projector is starting to show
its age and will need replacing. I was thinking that I ought to consider changing over to a digital projector but there seem to be several types. I seldom project onto a bigger than 4'X4' screen. Also digital images, what's the sort of file size that's required for reasonable quality? and will scanning my existing slides give good enough quality? (I have 2000+ slides and the thought of having to retake them all is a bit daunting!) I would be grateful for any hints, tips or comments from people who have changed over. -- Charlie Pridham, Gardening in Cornwall www.roselandhouse.co.uk Holders of national collections of Clematis viticella cultivars and Lapageria rosea |

This is what I use. Not wishing my Grandmother to Suck Eggs, but Power Point is very versatile. You can for example set a Slide Show up for the people to look at as they are coming into your show/presentation/talk. This can have background music if you wish and can keep rolling round. I had a roll round display at RAF Cosford Parade last year, .... no music there were already people doing too much talking. When you come to do your talk, your presentation and slides are already there a click of the remote or your mouse and the next slide comes up. If you are giving your talk from your computer, then your mouse pointer on the screen of the computer appears on the big screen from the projector. "What you see on the computer they see on the screen" If you stand up and operate the remote, you can use a Laser Pen to red dot the big screen. As someone said, your slides can be copied via a slide copier to your digital camera and thus the computer. I have a slide copier for an SLR with 42 mm thread, the new Samsung GX-10 has Bayonet fitting, I need to get an adaptor. Someone also remarked on having a high Megapix camera, my present has 6, the new 10 so I hope to have better definition. Your slides can be chosen as you like for a presentation with PPP and will stay as it is. I have 3 or 4 PPP's on my computer. Going down this line you will need an extension lead with two sockets on it, one for the lap top one for the projector. Photos can be scanned on a scanner them these put onto computer so your very old photo's can be done. I 'lifted' a picture of a World War 1 Hospital and it is now part of a presentation on PPP. None of this is Rocket Science I have learnt it all in about 18 months. "Doing it" makes it easy. But I do not consider myself to be an expert on the technicalities of it all, I am not interested, I just want to press buttons and there is the picture. I am more interested in the people :-)) Hope that helps. You know where am if I can help :-)) Best wishes Mike |

I think someone has mentioned a back up disk as well! -- Charlie Pridham, Gardening in Cornwall www.roselandhouse.co.uk Holders of national collections of Clematis viticella cultivars and Lapageria rosea |

I wish I had words of wisdom on this topic for you but I am not that
experienced with projectors. I just wanted to express that I understand the time-consuming and laborious task you have ahead of you. Good Luck!

I have been watching other speakers who are using them and have decided that a stand alone model would be best (one less thing to go wrong!) but its realy the images that are giving me cause for concern, particuarly ones which are a historical sequence telling a story, I mean you can go back and retake a flower picture but you can not go back in time! if I can scan some of those I think I may take the plunge -- Charlie Pridham, Gardening in Cornwall www.roselandhouse.co.uk Holders of national collections of Clematis viticella cultivars and Lapageria rosea |

You might find that good, second-hand equipment is a better bet than buying new - maybe from an AV Hire Shop ? -If you want to get really 'slick' then consider back-projecting your slides (projector behind the screen). Needs a special screen (not difficult) but means that you can be presenting in front of the screen, and no problems with silly blighters making shadow rabbits across your prize roses g Hope this helps Adrian |

Comparing will probably be a PITA as I doubt there is a standard distance used. So to make sensible comparisions you'll have to take the distance into account with the inverse square rule.

For PC read laptop and PowerPoint (or non-windows equivalent) you can add captions and/or explanatory/title slides in PP very easily. Does a stand-alone unit take a PP presentation or just image files? You might find a commercial service that will take a box of slides and scan them for you - depends how much your time is worth to you vs what they want to charge you. Go for the very best scanning you can afford. Preferably with the basic scanned immage in a "raw" format rather than anything compressed. Compression throws away information, you orginal scanned image needs to be the highest quality you can achieve. You then make your slides from that to what ever the current systems require. A decent commercial service I'd expect to produce a high resolution raw image then a selection of different resolution compressed ones per slide. Don't forget to take a backup copy or three of your scanned images, CD/DVD media *does* degrade over time. Maybe take another copy every year. Media is cheap, data is priceless. What is "high resolution" these days I'm not sure but I'd expect something over 2400 x 1800 and that's only 4M pixel, quality digital cameras these days are 10M pixel or above (4800 x 3600 ish) and a colour depth of at least 24 bits/pixel.
