newbie question: DOF in landscapes
HF distance means hmmm... how to put it simple, i hardly know to explain it myself :) The dof is so wide with a set apeture right? So with a normall photo you have. out of focus - in focus - out of fous What the HF distance does is brining the end of the infocus part to the end of your image...

newbie question: DOF in landscapes
I reread everything, the concept is clearer but not completely...don't know if I an slow to learn or it is difficoult... When do we have to apply the HF distance? There is something that I can't explain exactly but it is partially related to the placement of the subjects. I mean, I understand if...

newbie question: DOF in landscapes
HF is just something to get the most coverage out of the DOF you've. the point you focus on is the point DOF expand from. It expands to the front and to the back. If you set the focus distance to infinite and you use F/8 then the DOF expands to the front let's so to 20 meters but DOF also expe...

newbie question: DOF in landscapes
Max, there's another approach to this. Courtesy of digital photography where it costs nothing to press the shutter. Take three pictures of every scene, using different points of focus - one in front of centre, centre, and one behind. You'll soon get a feel for what works. Experimentation ...

newbie question: DOF in landscapes
If a subject is near infinite then it's very easy to get it sharp so it's up to you to consider what else you want to have sharp as well. That is right. So if the subject is at infinite and nothing in foreground, it is enough to stay for example with f/5,6 Max you've the K20D it has a preview b...

newbie question: DOF in landscapes
When the subjects are on the same plane, you have the perfect opportunity to use the lens at its "sharpest" aperture, f8 or whatever, because DOF will not be an issue unless you're very close to the subject. As George says, where you want to achieve focus on subjects at difference distances, experim...

newbie question: DOF in landscapes
Thanks! I appreciate that,I think I am ok in some conditions but there are still situations,especially in landscapes, where I have some difficulties.Maybe I am hard to understand on this matter! FOr example, what about 1-Do I need reduced aperture to increase the DOF and so to have the most on...

newbie question: DOF in landscapes
For that shot I would have used f8 or f11, focussed on the nearest building on the left hand shoreline (which is a pub or hotel IIRC), thanks! why? because it is on 1/3? because not recommended to focus on the water? Both? PS:thanks I have contacted that seller

Black and White Filters - Digital and Physical
There are many more filters than red, orange, yellow or green, but they are the most common ones. Current BW films are certainly panchromatic, but the problem is that their sensitivity is not the same as the human eye. We use filters to correct the reproduction of different colours so that we eit...

The other problem with Dell is that you can't upgrade the PC or laptops yourself and you have to send it back to them. I find this a huge drawback as I always upgrade things myself. Personally I wouldn't touch Dell with a bargepole. Yes customer service may be good if you haven't got a problem wi...

Iceblinker, from what I remember, and this wasn't recent, a couple of years ago, you couldn't do anything in regards to upgrading. It had to be sent off as I was told that it was all Dell specifications. If that has changed then I will take back my previous comment. Paul :)

I use an Acer 5920 (about £400), which I upgraded to 4GB Ram and changed the Sata 1 HD to a 320GB Sata 2 drive which sped things up immensely. I'm sure that anything similar from a respectable brand would be just as good, i.e. Toshiba, Dell, HP etc., Still running Blista Home Premium as originall...
