Capturing moving objects clearly with a blurred background
I would use the 60-250 wide open to give a shallow depth of field which would blur the background. There are moblie phone apps available which can show you the DOF at various focus distances. Probably similar things for a pc or mac. Jeff

Capturing moving objects clearly with a blurred background
If you do use a wide open aperture to knock out the background, you will need to go old-school, manual focus; pre-focus on a point and press the shutter when they pass through that point. Otherwise the depth of field may be too short for the camera to focus in time as they are coming towards you. B...

Capturing moving objects clearly with a blurred background
Like Screwdriver says use the telephoto zoom, wide angle lenses are not best suited to this type of action photography. I wouldn't shoot it wide open but fairly wide. Shoot in auto focus and burst mode (high) and with the camera set to continuous. Start shooting slightly before they hit the spot wh...

Capturing moving objects clearly with a blurred background
All of the above but I use TAV when shooting the karting at the local track and back button focussing ... These things are coming at me at about 80mph :shock: Be aware, you will not nail every shot so be prepared for some disappointing missed shots. But shoot loads and you'll get plenty :) PS...

Capturing moving objects clearly with a blurred background
New to photography so if you could dumb it down for me that would help also :-) Steve To get that subject to background separation, you generally want two things: 1) is a wide aperture, lowest f value your lens can do (or close to it), which gives a narrow band of in focus area. 2) some physical...

Capturing moving objects clearly with a blurred background
I agree with Richard, however ... start with a wider aperture value to start with, meaning more is in focus, and narrow down for the more stylised shot later one once you've got the hang of it. That bit ^ is the wrong way round. Small aperture number = wide open and narrow depth of field. I tota...

Capturing moving objects clearly with a blurred background
I'm guessing you want something like this? ... apart from it being normal cyclists. The idea being that you have a sense of movement. by , on Flickr This was done with the 60-250mm, you need to perfect your panning technique ... slow shutter speed, AF.C, multiple bursts and keep followin...

Capturing moving objects clearly with a blurred background
Might another option be to seek out an old manual focus lens and use 'catch in focus'? I got some decent shots of approaching racing cars (well, I thought they were decent enough) using a manual Tamron 500mm mirror lens and that feature on my Kx. Obviously that's quite a small aperture, but somethin...

K20d or K-r
I bought a K-r as a back up to my K20D and ended up selling the K20D and keeping the K-r as a back up to my (then) new K5. As John says, the K-r does handle better than the K20D and also has the advantage of being smaller and lighter. The only downside to me as an avid user of grips is that it d...

Tethering a Pentax
Spot on dangie. Used with Live View it gives you a live picture, or you can have a picture of whatever is being played back. Wahtever appears on the rear screen appears on the monitor or projector. Very useful for giving talks.

what size card for shooting in raw please?
Put your card in the camera, Louise; switch it to RAW capture; look on the back screen and you'll see how many shots you can take. 8GB might well be enough if you don't spray shots all around.

what size card for shooting in raw please?
with a rating of at least "45MB/s Where do I find that on the card please? Also is this a good card to go for/ Also this one? Yes, these are probably the best cards to go for. Sandisk are rated highly for reliability. As for which one: I'd go for the 16mp rather than the 32 which undoub...

Revelations: Experiments in Photography
OTOH, if you arrive at Paddington main line station, the signs to the Circle Line are pretty clear - don't know about South Ken but should not be an issue to find the Circle Line to get back again! There are clear signs from South Ken station right to the various museums. Just arrive after the mo...

Which file format?
For me now, TIFFs are used as 'Master Editing' files ... output from the RAW converter and then into Photoshop as 16bit TIFFs. Here I can use layers, adjustment layers etc galore and save with no compression. I usually flatten my TIFFs as I go and that keeps the file size reasonable. I know that I ...

Do you worry about 'bit rot'
We first made digital photos with a Sony Mavica camera that used 3.5" floppies, which we had borrowed, on a trip to California back in 1999. I bought one for His Nibs after that, which he used on our Route 66 trip in 2002. We can't view those photos now, they are so small. All gone. The ones I too...

Do you worry about 'bit rot'
The earliest RAW files are a bit tricky already Nigel, that is the Kodak ones in particular. A bit of a blow when the cameras cost thousands of pounds. For the time being my JPEG files are secure from our first digital cameras onwards and I expect they will outlast me, in theory anyway. The pace ...

Do you worry about 'bit rot'
Loads of photos stored on early computer formats which haven't been transferred to later methods will at some point get binned. I have been scanning slides I took decades ago and am impressed by how well they have kept, whilst noting the first images from the *ist D could have been better stored....

Do you worry about 'bit rot'
There's a thread on the other site about storage and back ups and it all sounds quite complex and expensive........... I just have an external HD that I copy files over onto as a back up. How far do you go to back up images? I don't really have a second location to store an external HD.....
