Welcome to the forum, I am relatively new around here and I can vouch this is a pretty friendly place. Being around here far longer than I have been I am sure you already know this

My apologies, I seem to have steered the thread from the main topic you started regarding ethics. In my zeal to want to know something extra when the topic cropped up blinded me momentarily and forgot to start a new thread with the issue.
Ironic we were just discussing ethics here and there I wrong footed.
Apologies again.

So you do use the auto feature for the sensitivity and leave it to Auto on occasion instead of manually setting the ISO, if I understood it correctly.
Just took a few shots by following the steps I read earlier and what a difference it makes when you know what you are looking for and make adjustments and also knowing in what precise way certain adjustments affect the shot. For the first time I could just view on the display and knew in which shots I had shuffled with the apertures and whether it was higher or lower. Up until now I had to keep taking loads of pictures and then slide the card into the pc and open the images in the pentax browser to see the exposure values
Thank you so much for all your help
Amin
Thanks

I tend to work mostly in aperture priority (Av) mode as I tend to shoot 99% static subjects - people with different shooting styles will vary accordingly.
My routine is something along the lines of: Set ISO (100 outdoors in daylight, 400 indoors), set aperture for desired effect (depth of field), check shutter speed fast enough to hand-hold (and adjust ISO upwards if not until it is), take shot, check histogram, adjust exposure compensation +/- and repeat until satisfied.
If I'm using either a tripod or flash then I tend to stick to ISO 100 as shutter speed is *generally* irrelevant in these circumstances.
If I'm shooting fast moving objects then I'd tend to switch to Shutter Priority (Tv) and work through a similar rota but with the first part reversed: Set ISO, set shutter to required speed (to stop or blur action accordingly), check lens fast enough to accomodate (adjust ISO upwards if need be), take shot and hope for the best 'cos you rarely get a second chance with fast-movers!
I can understand now why the easy short cut menu for the control of sensitivity on the K20D. By pressing keeping the OK button pressed and then green button to bring ISO to AUTO or keeping OK button pressed and rotating the Front e-dial to choose the ISO values. . Fantastic stuff .
One question please, are there any instances you would choose to keep ISO on AUTO? as an example? And the Dynamic range, I notice also that if I choose to keep that on (had a brief reading about Dynamic range around some sites and more specifically to do with the K20D) then minimum ISO possible is 200 only. Your take on this please?
Thanks

Thanks very much for that brief explanation. I will eagerly await for more. The way you have explained definitely adds more in my understanding.
And do not worry about the fact if you might be explaining something that I might have already a grasp on it, even if I have, reading through someone else's perspective and explanation always adds a new dimension to the knowledge. Proof of that is although I had a brief grasp on what exactly ISO, shutter speed and aperture are and what effect they have on a picture by changing the values, reading your explanation and cause and effect on those three, more specifically
If you just use the camera as a point and shoot, it will choose what it thinks is the best combination of aperture, shutter speed and ISO. Usually, you will have set the ISO before hand, and so it chooses aperture and shutter speed on the distance to focal point, and general light available.
ISO, aperture and shutter speed are all interlinked. To have the same amount of light fall upon the sensor, by halving one, you'll double another. if you have a constant ISO (say 100) and take a shot at f8 and 1/60th sec, to take the same shot with more depth of field, you'd change the aperture to f16. The camera would then adjust the shutter speed to 1/30th of a second to keep the same amount of light falling on the sensor.
Conversely, if you wanted to reduce blur by increasing the shutter speed to 1/125th of a second (the doubling/ halving is always close but not always exact.. historically) then the aperture would adjust to f4, so that you get the same amount of light falling on the sensor.

Thank goodness for the SDHC cards with massive storage .
Thanks so much for your help and I will eagerly await more when you are free

I certainly agree with Amin - this community is superb and I would have no ill feeling if someone edited a photo I had uploaded here to convey what might look better - I'm always keen to learn as I'm still a newcomer to DSLR photography.
I've actually been reading a lot of Amin's posts (not deliberately) - it's just i've been very interested in his questions on lenses and recently his delve into macro photography - and i've always found the answers by this community to be a great source of information. A previous post of his and your answers helped cement my decision to get the DA 55-300 with my K20D.
So just to encourage Amin - your questions have'nt been too basic for me, please don't stop!
hehehe thanks for turning me into the head of the wagon for us newbies into the beautiful world of photography, and DSLR more precisely.
I know precisely what you mean also because I look around the forum and many times its the questions that the newbies come up with that suddenly remind me that its one of the many questions that I had been wanting to ask. And the bunch here is really friendly, in many other sites we would have had already someone throwing a less than pleasant remark telling us to go and look here or there first, in other words saying not to waste their time here with very basic questions. .
Now that we mention questions, there is one that has been bugging me for a while now and dying to put it up here. . Who knows this might be just pushing my luck a little bit too far, but hey people, please bear with us, we are just so engrossed with the field that at least in my case I look like a child who has found the perfect toy to play around. I have been waking up in the middle of the night and wanting that daylight breaks quick and hope for some sunlight so i can go out there and get some pics and experiment. There is one aspect that would really help a lot if someone could give us some brief explanation on the applications of the Exposure Modes and the best usage for the main ones.
Basically I would like to know by way of example when one would use the separate modes. I have read the manual front to back and am quite well familiarised on the controls now and the terminology and its meanings and what it does specifically. I find myself using the P (Hyper-program) mode most of the times, and then try the others also, but if someone could give us some hints that would be extraordinary.
One example by the way is when I saw the image in this thread by iceblinker https://www.pentaxuser.com/forum/topic/new-lens-9604/p-3 and although I see 1/4000 iso100 f2.5 in the picture, I suppose there are different ways (modes) of acquiring those shutter numbers, iso and aperture, but if I could know what exposure mode was the dial at that particular shot that would be such a great help in me understanding it.
I know for you more experienced people this now comes naturally, but I found that this is definitely holding me back in my further advancing and exploring a little more the field. I catch myself taking various shots on different modes and trying to compare and spending hours doing that, but hey, thats all part of the learning process and I dont mind it, but it would be helpful if someone gave us a little push please.
Now I do apologise if this has been discussed before, in which case please can someone guide me to the appropriate thread or links.
Many thanks
Amin

But as time went by and with the number of questions I kept on asking I was brilliantly impressed by all the help and patience I was getting from around here. It is true, the analogy that this is like a friendly neighbourhood where one can leave the doors open is entirely true. I relish the time I spend here reading the comments and interacting and the knowledge I have gained is absolutely phenomenal in relative terms compared to what I knew about the subject.
So I do echo what others have said, I think very few would object that their images are manipulated and then put back, I personally dont mind at all, and Stefan asking my permission just shows how polite people here are and are concerned with good manners and attitudes. In fact I am quite glad someone takes the time and effort to do something of the kind and gives me a feedback to enhance my knowledge in the field.
But also I see that the more experienced veterans here commented something which is entirely true, knowing human nature one should try and find a compromise to avoid a misunderstanding, an attitude which meant good but was perceived to be detrimental from the other person's perspective,
Courtesy and common sense will answer this. If in doubt ask the photographer as sometimes people post things but only want glowing approval, most times people who ask for opinions mean it!
thanks
Amin

Talking about kitchen windows Pete, I have been wanting to ask this, although its slightly off topic. Up to what extent detrimental effect does an image have, taken through a glass door or window? Anyone with experience care to comment on this? Taking for granted of course that the glass is as clean as possible of dirty spots. The reason I ask this is because I would love to take more shots of wildlife that proliferate my back garden Something to look forward to sitting down by my patio door and capturing a few images.
What I do know is that depending upon the angle of the sun (when it decides to make its prestigious appearence with this climate ) sometimes the glare does destroy some of the images. I tried a few times but I decided not to persist thinking that its a no go area, but now seeing what pete posted and that he managed to capture that image through the kitchen window perhaps I should persist and see what I get. At least would have more oportunities rather than tucking myself and going into the backyard and spending sometime there in the cold. Much more apetising with a cup of tea indoors by the patio door, which is a wide one facing directly a long deep garden that I am lucky to have with quite a few trees. Lots of squirrers also around so here I go

When it was released it was at that price but now its surely lower. Check the site also for other reviews. Not sure if there are many. I ran into this one when I was looking to buy one then, but put it on the back burner. What appealed to me was the networking possibilities that the frame has. Very handy if you have a network at home, which many have at the moment.
I use EOP (Ethernet Over Power) so now I am seriously considering a picture frame as this way I can make full use of it rather than wirelessly which can be sluggish and slow around the house. With the electrical wiring now carrying my signal the speed has increased massively and all I need to is just get one more slave for it.
This is one site I always go for any gadgetery reviews before buying, have done it for years and never been disappointed. In fact it was by reading their reviews regarding the K20D that made me decide to go for it just a few weeks back , The review was eye catchingly titled "Pentax K20D digital SLR, This is the most powerful semi-pro DSLR in the world, and will blow your head clean off"
