[snip] I'd aim for full HD 1080p if buying new these days. My question is, does anyone here use the cheaper LED projectors and is the picture quality OK? (ie does it compare with an old fashioned slide projector) I suppose I normally project onto a 5' square screen and can chose the distance, normally evenings so I don't need to project in bright light The other thing to look out for is local voluntary groups who can make projectors & OHPs available to hire/borrow for educational talks. Many thanks for all the replies, I have decided to go for something fairly modest price wise on the grounds that a lot of the bigger clubs do seem to have their own kit, so I just need something here to practice with! and that should help with the bulb life (using someone else's!!) I also think I have found somewhere I can go see some projected images (mine) on various projectors which should show me just how much resolution or lack of it I can put up with. The other thing it is worth treating yourself to is a combined magic dongle and laser pointer that makes next slide and previous slide easy. It is a big improvement on saying "next slide please" all the time. I wouldn't recommend anything less than 720p these days. Also check the performance on the sort of material you intend to project. They will all do skin tones really well but some may be a bit vague usually along the line of purples where many flowers are clustered. No conventional colour film could reproduce the true saturated purple/magenta colour of Notocactus Ubemannianus flowers reliably. Digital is better but they still dump residuals in the line of purples so as to get critical flesh tones optimal. The eye is very sensitive to abnormal flesh tones or colour casts which may indicate disease. -- Regards, Martin Brown |
