Digital vs Analog projection

[stefan_lindgren]

<p>I'm just in the middle of a comparing test with a trusty old Leica P150 tt copmpete against <br /> a Panasonic PT-AE3000u digital projector.<br>

I would love some feedback and maybe requests for particular tests and questions that might<br /> have crossed your mind regarding this subject.<br>

<p>I'm not sure if your test really shows the differences of the projection systems, or if it shows the limits in the scanning devices.</p>

<p>I believe for a more comprehensive test you should have the following 4 cases:<br>

- The scene taken with a good lens on slide (A)<br>

- The slide (A) scanned<br>

- The scene taken with a good lens and a good digital SLR camera ©<br>

- The image © copied to slide in high resolution.<br>

With these four cases, you feed the input of both sources (digital and analog) into<br>

both projection systems.</p>

<p>I'm wondering who would care. I haven't seen a public display using a slide projector in nearly twenty years. In the business world, overhead projectors prevailed until digital projectors were invented, and that's how it's been ever since. Think about it! You can travel to a remote site with nothing more than a CD or DVD in your briefcase, or at most a laptop. Digital projectors are a standard fixture in businesses, schools and museums.</p>

<p>I recently scanned about a hundred wild flower slides for a state park, and prepared a PowerPoint slide show complete with notes. The client(s) have used this file for a variety of purposes, often edited and rearranged for seasonal and topical reasons. It's hard enough with conventional slides to keep them in any reasonable order. The hardest part of my job was to catalog the slides so that any image could be related to the original. To revert to a slide projector with a stack loader (shown above) defies reason.</p>

<p>Three points:</p>

<p>1) You seem to think the digital projector is superior or the same as the projector. The samples you show to my eyes show the projector superior in sharpness.</p>

<p>2) The Leica P150 is not a particularly good projector - its OK, but not a patch on one of the "professional" Leica projectors. The lens is a good one however.</p>

<p>3) I am not sure why color balance is such an advantage for digital - surely when you shoot slides you pick the slide film you want to get the colors you want? That is one of the reasons to shoot slides. I'm not sure I really follow you here. Are you referring to the ability of digital to handle tungsten and fluorescent lighting?</p>

<p>Stefan, it seems to me that you are predisposed to liking the digital image :-). In the first crop of the building, both detail and color rendition from the analog Leica, to me, are head and shoulders better. In the second crop of the tree against sky, you simply mention "some color fringing" in passing, but to me that is the predominant factor in the crop and I would characterize as "significant color fringing" on the digital Panasonic. In the third crop of the flowers, the analog Leica crop is plainly cleaner. I am completely dumbfounded as to how you can call the Panasonic results superior. Of course, I am sure, the scan from the Canon FS-4000 is a factor in the image as well, not just the Panasonic's fault.</p>

<p>I have always liked the impact of 35mm slide projections. I am interested in finding a digital projector solution for scanned 35mm or even medium format slides. But doesn't look like we are there yet. I am a big fan of consumer DSLR photography as well, and miss that impact. No print, nor a contrasty and saturated LCD display, has so far bypassed the impact of a well exposed slide, it would be nice to know what a DSLR shot of the same scene looks like projected via the Panasonic.</p>

<p>I reached my goal, I created a debate :0)<br /> And I was sure that I would hurt some feelings and get fingers pointed at my method and thoughts. <br /> But still, I do like the Digital better in most ways not only because it is convenient but also because<br /> it gives me much more alternatives to variate my slide show.<br /> <br /> In pure sharpness the good old slide projector is the winner but only if you enlarge the details in the way I<br /> did in my shoot out test.<br /> <br /> In the real world situation you would look at the image from a distance that would not reveal most of<br /> the faves in the digital projection, instead other thing like rich colors and overall appearance will make the<br /> digital image to look better for most people (Except for them who walk there way to the screen and examine <br /> the image at a 2 feet distance).<br>

Just feeding the fire/ Stefan</p>

<p>Yesterday night I wipe the dust from my analog projector! I went through my Lieca m6 50Velvia! I really injoy the great dynamic of these slides! it was like real thing. (just a comment)</p>
