Okie...my boss just left town...so have abit more time to write my two cents heh...
yup. Bought a new d70 and read that I should get a filter to protect the lense - for some reason I was sold a polariser.. didn't think anything of it. Oh well. I have one now
Damn you got con in a way then
Well that partially explain the surprise you got when you used it on your lens. Now...if you are into shooting outdoor scenes and want deeper blue sky or ( there must be blue sky to begin with okay? It does not do it by magic heh) enhance overall colouration ( it does not always work as you will find out and as you get better at using or not using it) that filter purchase is a blessing in disguise. I have a feeling it did not cost you too much too as you bought it without much fuss (?) because if he was to have sold you a Nikon or B+W polariser...you would have rise hell for sure as it cost an arm and a leg...or one cheap zoom lens! heh For now anyway...forget the more costly ones till you get better at photo taking.
No one would use a polariser to 'protect' their lens for one very important reason. Filter's darker tint. You noticed? heheh. Dark tinted filters tend to "steal" from you in terms of shutter speed (imagine without the filter on, the camera in Auto mode might set up your shutter speed of 1/125 for the apeture opening you dial-in. With the filter on, you could now be shooting at 1/60 or worst 1/30 due (at the same apeture setting) to less light entering your lens due to the darker tint.
So now shooting at 1/30 speed would require that you be pretty steady with your hands cradling your camera. So unlike shooting at 1/125, at 1/30 you need to be more steady. At slower shutter speed, you hardly can get away with it now! heheh..I suspect that is why you find yourself getting more blurred images with the filter on. Also note, it matters not even if you shoot in really bright sunlight, a tinted filter will always steal about 1-2 stops from you..just that in brighter condition you get away with it better as you might still have much higher shutter speed left to you..etc Hope you understand what I mean. I am trying to explain it as plain as I can since you might not be familiar with photo equipment.
You can stop it from "stealing" your shutter speed, in a way. By selecting S mode which is speed priority. You set the speed say to 125 but let the camere select the apeture opening for you. Say for example it select f11. Now when you place the filter over the lens, the camera will noticed it is darken now with filter's dark tint, so it automatically will re-adjust from f11 to f5.6. This works Fine if you are not fussy about depth of field. But of course this can only go so far till you run out of f-stops heh.
Either way, they have their limits too as you will soon find out as you get familiar with your equipment. Learning to balance the use will give you varying image difference which is where creativity comes into play heh BUt that is another story.
I'll try it on a blue sky day... I've NEVER used a polariser before. and I don't know how to use the D70 fully yet. Been on a P+S before :sweat: I mostly shoot in Aperture mode - still getting to grips with the camera.
AH!...okay...this might have escaped you or the fellow selling it to you might not have told you. The polariser MUST BE ADJUSTED for OPTIMUM enhancement. If you take your polariser out now and look at it closer, it is made up actually of two free-rotating rims or rings mechanicaly linked to form one filter. Unseen by your naked eye..the polariser is really a special screen filter. By looking at a scene or subject through your viewfinder, when you rotate the outer rim slowly, clock wise or anti clock wise,(when you have attached it to your lens) you will start to realise what a polariser is all about. You will see some surfaces start to get darker in colour, lose it's sheen or reflection too in the case of some glassy surfaces giving you a clearer definition of the scene or object(s). Oh...you can also do this by just holding the lens to your eye and then you rotate the entire filter clockwise or anti-clockwise. As I said, the angle of lighting hitting your lens or eye must be from a certain angulation so sometime it works very well, moderate or sometime it does not. And sometime it works on certain parts of a whole scene while it does not effect other parts. So playing around with it abit will help you get a better understanding about what polarising a scene or object is all about.
NOw your the other problem being the colour you say was not as good as when you shoot without the filter. One thing some people don't notice is that a polariser can not only enhance colour but it can also do the opposite when used wrongly especially when the contrast is bad that day you are shooting or certain surfaces even. Some get that greenish tint or yellow...etc. A polariser basically filters light rays....very much like when in school they teach you that a glass prism can break down white light to create rainbow colours. Something similar happens here. The polariser is not to produce blue sky as per say..so don;t misunderstand that it is ONLY USE to make the sky more blue or create better colour or deeper colour. It just "seem" to do so. What it really does is take away the glares and just letting the true colour of the surface come through to your lens more "purely" (trying to be as layman as I can get heheh ). When I do product shoot in my office which is indoor. I sometime use a polariser. Why? To help me minimse the unwanted reflection or glare that is seen on my product I am shooting. Maybe one day I will shoot some stuff to better illustrate this to you. Suffice to say, I am just trying to give you abit more information so you don;t think you bought yourself a "lemon" system. LOL. I swear by all my polarisers. I use them each time I get if it can somehow enhance the shots. And no I dont use it to "protect" my lens heheh.. In fact my polarisers NEEDS protection themselves!!!! heheh.
The photos are taken out of my apartment here in Sydney. No windows between me and the view.
Okay got it...but as I have mentioned above..it is a case of slower speed and slight hand shake that is now more pronounce due to slower speed since you might be shooting in A or P mode especially. One final tip for you about using the polariser. No matter if it is an over cast sky, very sunny day or whatever situation "inspire" you to put the polariser to your lens, always...always...recheck your shutter speed in your viewfinder to make sure it is fast enough to be hand held for the shot.
Here's some photos I took yesterday without the damn filter. Stupid = me. Anyhow.. taking it off seemed to have fix the visual quality of my photos. Me in :heart: with the D70 all over again. Could someone comment on the post work - I like my blacks crushed + higher con images
Yes I have to agree your photoshopped version looks very much better looking. That is the good thing about digital photography, you have abit more control over your final results if you are handy with digital desktop graphic programs. Sure there will always be debate on that issue of shooting better and less correction blah blah blah... But that is the future of digital photography and previously with film photography, you need to have your own darkroom to do all that but now anyone with a computer can do so but of course with more creative control means more work on your part to learn how to do it and spend time touching up or reformat your pictures. But then again...if you want to leave it as it is..that is fine too. Uninstall photoshop from your PC or MAC and spend more time practicing your shooting with the camera to that point your shots don;t need an inche of manipulation to improve it. If that is ever possible at all heheh BAH!..that will never happen heheh...at least not for me. Well hope that clear up some doubts about your polariser problem heh..
