Default I Did the filter/no filter test

Might as well do it since I got my tripod setup and all that. I've been curious about it, guess it's better to see it for myself. Well, the short answer is, yes. It does make a difference.
I don't really see difference in sharpness like I've read somewhere, but more contrast can give this perception of more sharpness, so maybe that's why they said it decreases sharpness.

I did several tests with different conditions, and the results were consistent, when the filter removed, the image showed a slight contrast increase.

This first set is wide open indoor ISO 800



And this is when the filter is removed:






Second set, same ISO (different aperture):




Without filter:





Last one, this is from the back of my apartment, the main brick unit is, dunno, maybe 80m away? Set at f/5.6 focus to infinity, ISO 100.



Without filter:





I tried to look at the off centre, distant image, and it still shows difference in contrast. This is the crop:




But then, all this difference can only be noticeable if you really look hard. So now I think I'm back to square one again, whether to remove the filter or not, lol.

Damn... enough pixel peeping today for me (or maybe forever). This is boring, lol. Time to shoot real pictures! (but the question is, filter or no filter? lol) :allteeth:

disclaimer: I do not support the practice of shooting brick walls or charts. But I do support portraits with nice bokeh.

this is camera related but not necessarily nikon related so i hope you guys don't mind. maybe the fact that i love my d50 makes up for it? i've finally decided that i need a tripod. can anyone suggest one that isn't overly expensive but is light and sturdy so that it can be brought along for long hikes and won't be blown over by the wind?

I don't have much experience with tripods, but the information you need to provide in general are such as: budget, weight preference, height preference, your lenses (eg. do you have very long, heavy lens), type of shooting (macro, or panoramic, or portrait, etc), do you need a removable plates, etc.

I got one of those Manfrottos 728B but now I feel like I wish I put more money and get a better one. It works and support my camera, lightweight yet sturdy, but it's not as good as the pro series, but they cost a fortune.

question, I'm on a strict budget and I have now a choice between the nikon d40 kits lens and the nikon d70s with the 18-70. I dont care right nowa bout the lens limit on the d40. So in terms of better overall image quality which one would eb a better choice and is the d70s worth the extra 250 over the d40?. budget is 800.

There really isn't that much of a difference between the 18-55 kit and the cheapo 18-70 lens, so it's really between the bodies. I personally find the D40 a bit too limiting, so I'd go with the D70s.

Really? Well, I know sometimes the discussions border on hypercritical at times, but it's still the best Nikon knowledgebase. Is that what you heard, or was it another issue?

Re: I Did the filter/no filter test

dj_mocok:

Thanks for doing that. It would be interesting to do a couple sets of filter on/off shots, post them without identifying which is which, and see how many of us can distinguish between them in a poll. It would also be interesting to introduce two levels of filter quality into the mix.

If you ever get unlazy again ...... Or if I ever get unlazy, period.

I think the main danger of leaving a UV filter on is in a high glare situation ... especially when a lens hood is absolutely necessary to shield the lens. The filter effectively lengthens the lens by 3/16" or so, which can push the glass out beyond the hood's shaded area making the lens hood un-effective.
