Why we don't need FF
It's not really true though, is it, that sensor size directly relates to size of possible output. I thought actually that was in fact resolution? Resolution and sensor size are different things. I believe sensor size influences other IQ factors also, dynamic range being a key one. Potential maximum ...

Why we don't need FF
It's not really true though, is it, that sensor size directly relates to size of possible output Of course there are variables, but to all intents and purposes a larger sensor will usually give more opportunity for a satisfactory result at large scale

Existing Owners Just Ecstatic
Those price level changes were announced many months ago to Hasselblad owners and prospective owners. Most of the price level changes were due directly to upgrades in sensor technology; Hasselblad moving to CMOS. Almost all of the new CMOS level sensors have not changed prices (at all) since their r...

Pentax Camera Image Controls vs Computer Editing
I wanted to lay down some thoughts on the recurring theme of 'in-camera' capture and computer image editing. It would be good to set out some goalposts and try and establish some common understanding for these debates, as I feel they are often confused by misunderstanding, termonologies and people a...

Pentax Camera Image Controls vs Computer Editing
The digital filters and so on only apply to the JPEG file. In fact, we can't shoot RAW at all in some modes, such as HDR. There is another argument of course that, far from being a weak processor, the JPEG output of a camera is carefully tweaked by the manufacturer to get the optimum from that pa...

.... Like I say, I'm not looking to derail this conversation with the 1 hour lab comment, .... :D No worries Richard, frankly these sort of debates tend to take on a life of their own .... certainly I, as the instigator, usually find it's hard to keep the troops in line! :) Look, already just abov...

Pentax Camera Image Controls vs Computer Editing
Hi petro, good to have you joining in :) The division I'm defining here between 'input' and 'output' is really based on whether the particular control or function is a 'physical' or optical function (like aperture, time value, focus) or a quality 'burned' in to the sensor data (like ISO) ... these ...

Pentax Camera Image Controls vs Computer Editing
The purpose of the 'input' / 'output' classification of camera controls is to lay down some firm guidelines, and help in how we consider post processing actions, and hopefully achieve better agreement on the appropriatness of specific types of 'photoshopping'. To me there is a clear division between...

Pentax Camera Image Controls vs Computer Editing
I'm looking at ISO as being a setting that 'burns in' certain IQ characteristics at point of capture - noise levels being the most obvious, but there are tonal and colour changes at higher ISO's also. I see it as in the same category as aperture, time value, focus and flash lighting because it has n...

Pentax Camera Image Controls vs Computer Editing
So for this reason, by my definitions, it (ISO) falls firmly within the 'input' category. Your original definition of Input Control was: "1) Input Controls directly affect the 'physical' optical image capture ...how the camera optics perform and the way the sensor records that optical image data....

Pentax Camera Image Controls vs Computer Editing
Does anyone ever really use HDR in camera? It is rare with the K30 (or any camera with the 16mpx Sony sensor) that you'd really need to worry much about high contrast scenes. Shooting in RAW, spot metering the brightest highlight and opening up 2.5 stops, followed by "normalising" the expos...

:D Well I did say this sort of thread can go any which way! All interesting stuff chaps ... I did think you were asking for it John, in telling Andrew that HDR was good for churches ! :mrgreen: In fairness, I'm hardly the most committed HDR evangelist ... I too have not fired up Photomatix latel...

Pentax Camera Image Controls vs Computer Editing
Glad its been fun! That's that idea. I love taking pictures, but that can't always be done any time, so the next best thing is thinking and talking about it :D I do like to theorise about things, especially where the man/machine interface is involved ... but I do this as I genuinely believe it leads...

Why video on a DSLR?
The camcorder is properly designed to do one thing very well. Not disagreeing with that, but seriously, this is the same old response to a feature that Pentax has had for a large number of models and years now. Time to get used to it I think. If you don't want to use it, don't select that mode st...

Why video on a DSLR?
From what I see, these people who use video seem to be complaining that "video is rubbish on Pentax cameras" and keep asking for better video - then go and buy a video camera!:roll: See RobL's comment above Look harder then. Pentax has awesome hardware, but their software implementation of t...

Why video on a DSLR?
Motorised zoom? Pan and zoom in one motion? Basic stuff. = bridge camera. Narrow depth of field, wide angled lenses, physical sensor stabilisation, weather sealing, larger sensor for low light abilities and wider dynamic range = dslr If you are after basic tourist handy cam then all good, bu...
