Silkypix Developer Studio Pro 5.0.50 K3 PEF Support
Is Pentax still keeping that cr*p alive? PDCU5 is Silkypix run through the destructive hands of Pentax' software hacks? I thought they were supplying the original Silkypix, just not the latest incarnation. This sort of ignorant stuff is hardly helpful. It would be better to step back and consider h...

Silkypix Developer Studio Pro 5.0.50 K3 PEF Support
Hi David. You can't. It is restricted to only work with certain cameras. In theory Pentax could update the program to accept more models but that has not been their approach so far. The company behind Silkypix would be happy to take your money for the full program - and then we are back, full ci...

Camera on a Motorbike
Here's a question I'd like to throw to the pack... I love to take the camera and a couple of lenses out on a bike ride. Always easier to get to the hard to reach spots and I usually pack the camera in a pannier, not ideal and my latest steed doesn't have said bags. Anyone got ideas for a good ...

Camera on a Motorbike
I often head out on my bike with camera gear and always use my back-pack. For what it's worth, I wouldn't dream of using any bike-mounted luggage for any of my camera gear. I wouldn't risk the general vibration or shock from pot-holes.

If you where to come of the bike and land on your back with a rucksack full of hard camera gear, you could do some real damage to your spine. Use a tank bag or proper designed metal panniers. Cheers Dave

Carried cameras in the panniers on an R80RT since 1984 in hard and soft (Lowepro) bags. Never had an issue. As for a back pack, great. Also carry your security chain around your torso so it can also break bones and tissue in a fall. Solid objects in pockets also help to increase damage to t...

Camera on a Motorbike
I'm looking for a solution to the same problem, though I also want to be able to carry a tripod on the bike without having it on my back. The panniers I have looked at that will fit my bike (Harley Sportster) don't seem ideal for camera gear. I'll probably get a rear luggage rack, not ideal as my ca...

Camera on a Motorbike
As others have commented, a back pack is the best solution for the camera and lenses, but potentially the worst solution for you in the event of a spill. If I have to take my DSLR kit I normally resort to the car. If I must take it on the bike then it goes in the top box with lots of padding to abs...

Something to ponder!
I don't believe a word of what Chris has said! :shock: :mrgreen: :wink: The PhotoZone article is spot on. If it were anything else a magnifying lens couldn't exist and all optical science would have to be re-written :shock: The article is self explanitory. -- Algy, at risk of getting my ...

No Tony. And certainly no Algi, you haven't looked at their images properly. Tony, if you want the same field of view and perspective to a 85mm lens as on 35mm film, then the nearest in the Pentax range is the 55mm f/1.4 lens. The reason this is true is that you need to stand in the same place...

The 100mm view will produce almost parallel perspective lines because it is a magnified view. Similar to watching horse racing on TV the horse only moves slowly towards you because the distance appears compressed. It's actually the horse that is magnified. Cobblers. The perspective lines ar...

Something to ponder!
JAK, I was only referring to ISO and shutter in relation to creating the same image in relation to how it would look, but I had not thought about the horizontal angle and the diagonal field of view measurements. Changing the ISO, shutter speed and aperture would only affect the depth of field (ie ho...

Something to ponder!
Well, if I could bag this thread, it would do my roses a power of good. First off, there has been a lot of talk about perspective without saying explicitly which perspective you are talking about. Yes, I can see that it is linear perspective, but there are several other varieties as well. Yes, m...

It matters if we want to understand what we are doing I aggree with John, understanding how changing focal lengths/position affects the picture is important in getting the picture you are after. Changing the focal length does not have the same affect as stepping forward back when framing an image.

It's quite clear from the sketch..... you can take the kerbline all the way back to the vanishing point and the angles will not alter and they will always be different for a WA and Tele. In the sketch the WA kerbline is about 40deg off vertical and the Tele is about 7deg. One normal use of a ...

It's quite clear from the sketch..... Algi, stop drawing sketches and Do the bloomin' experiment.> All you need to do is what Tony did. Stick the camera on a tripod, take two images at different focal lengths, crop a chunk out of the middle of the WA one to match the narrower angle of vi...
