The 'correct' colour is not at all easy to define – do you mean that the colour on the screen is the same as that of the original object when that object is illuminated by the same intensity and colour temperature light as that used when taking the photograph? If that's your criterion, then if the camera was correctly profiled to use Adobe RGB 1998, then the Adobe RGB 1998 image is correct, provided the viewing device is correctly profiled. If the camera is correctly profiled for sRGB, then the sRGB image will be correct. Anyway, I didn't say that one or the other is correct, I said that they were perceptibly different. About your portrait, do you know whether the President of RPS used a digital or film camera? If the latter which film did he use? Did he allow for the colour characteristics of that film? And so on, and so on.

The colour management forum stream ran out a few months ago, but I'd like to start a new one by asking Igor to incorporate proper colour management in PTE5. As far as my very limited tests show, PTE5 will need very good graphics cards to run smoothly and I think Igor said somewhere that he would need good graphics cards to incorporate proper colour management. So this is your chance, Igor! Give us proper colour management with PTE5!! Digital imaging competitions are becoming common nowadays, and, in Kent at least, several clubs already have GretagMacbeth Beamers to profile their projectors (thanks to Lottery grants), so now we should bite the bullet and show images with their correct colours. By the way, I looked through the old forum stream before writing this and noticed that some people said you can't see the difference between sRGB and Adobe RGB 1998 -- WRONG. Try this simple test: load a colour image with a reasonable range of colours into Photoshop and duplicate it; set one image to be in sRGB and the other in Adobe RGB 1998 and resize them so you can see them side by side. You can do this either on your computer monitor or on a projector screen. I haven't found anyone who can't tell the difference when they can see the two images together. That includes me and I'm partially colour blind!

Both demos very good on my Radeon 9550 with digital connection to 1280x1024 monitor and Pentium 4 running at 3.4GHz. Very slight stutter noticeable on horizontal pans when a new image begins to appear — this happens every time this situation occurs and every time I run the demo. Sound quality on pteshow a bit muffled, perhaps the original file wasn't too good? Occasional slight stutter on flowers demo when new image begins; it seems that loading and preparing the next image stresses my system just a little too much. No sign of memory overun mentioned by others. Overall — absolutely marvellous!

Good sound cards on laptops seem to be very rare -- I just avoided the problem by buying an external sound card. Mine is made by Creative. You can choose USB or PCMIA versions -- I chose a 'Soundblaster' with USB connection so I could use it with any computer at a cost of just over £50. I'm very impressed with it and would recommend it heartily. I've just seen that this has already been recommended! So I'll just say that it;s very good!

Multiple monitors are easy with most laptops already. For example with Acer laptops you press 'fn' and 'f5' simultaneously and that toggles between screen on its own, screen+projector, and projector on its own. I'm sure most other laptops have a similar feature -- no need to bother pic2exe at all. For competition presentations, the best program I know is ImageCompPro obtainable from roy_moore@maidstone32.freeserve.co.uk It does all you want and more! Sorry this reply is a little late, I've only just got down to page 14!

The human eye/brain combination can easily be misled over colours; see any book on colour vision. In addition, about 10% of males have some form of colour vision deficiency (I do). Therefore, it's safer to rely on hardware calibration if you want to be sure of the end result. The Eye One Beamer creates a profile which sits in your computer between the colour managed images and the projector in exactly the same way as does the monitor profile. I said before that pic2exe is not explicitly colour managed -- that's true, but it seems to work very well provided all images have the same colour space (Adobe RGB 1998) and the projector has been profiled correctly. Of course, if you're sending a file to someone else and have no control over how they've profiled their projector/monitor, you're at their mercy and will probably get the horrible 9300K, over-saturated, high contrast images I see far too often! Join those of us promoting proper colour management!

I'm very fussy about correct colour management and always profile the projector using a Gretag Macbeth Beamer before every show. I've found that people can see the difference between sRGB and Adobe RGB (1998) on a projected image with a properly profiled projector. I'm very careful to ensure that all the slides have Adobe RGB (1998) profiles and that, as far as possible, they are saved using Photoshop JPG level 12. Although pic2exe doesn't explicitly say it handles colour managed images and projectors, it seems to do a very good job. In my last show, I was projecting onto a screen 300 cm wide, and the audience of highly critical photographers were amazed at the quality of the images. By the way, Windows colour management doesn't work too well with greyscale images; fortunately it's easy to convert them to RGB at the last moment before saving. Another by the way: pic2exe behaves badly with CMYK images; the image sequence stops at the image before the CMYK one, but the music goes merrily on. Once again, a last minute conversion avoids the problem.

Recently I've started using pic2exe to support talks I give, I set left click to move onto the next picture and right click to go back, I hide the mouse arrow so it doesn't clutter up the picture; works fine no problems. Now I want to have button(s) in some pictures so I can go off along another path and then come back to where I left the original path. But I can't see the mouse arrow! Remember, I don't want to have the mouse arrow showing all the time. Here is my suggestion for a new feature: in individual slide options have a 3 radio button option: 1) switch mouse arrow on, 2) switch mouse arrow off, 3) leave mouse arrow alone (i.e. keep global setting). I hope you can do this, Igor.

Remember, I don't want to have the mouse arrow showing all the time. Is there a way of setting individual slide options to switch the mouse arrow on and off?

I have used Nero to produce DVDs and sVCDs from p2e with no problems except that it seems to be an unnecessarily complicated process. Would it be possible for p2e to have a dedicated link to Nero as it does to some other burning programs? By the way, I find that a typical sequence takes about 1 to 1.5 hours to produce a DVD. I have no way of knowing whether this is abnormally slow or what I should expect, can anyone tell me?
