Getting UV filters is waste of money, there's hardly any UV leaving the lens to the sensor due to the coating of lens elements. Usually newbies will get lured into buying them by eager sales men, telling all kinds of horror stories about damaged front elements. To each his own, but for photography with digital cameras it's pointless to use one.
On the other hand, GDN and CPL are quite useful and for long exposure shots the ND filters are mandatory. These filters and their effects cannot be simulated later in post-processing. (Maybe GND, with limitations).
I beg to differ.
The very first filter that go onto each and every of my lens is a UV filter.
I am very sure any one of us yes would rather have our UV filter scratched, than the glass element of the lens scratched.
One can argued that with really really good care, you would not need UV filter.
I agreed but i rather buy insurance.
I am a newbie photographer and would like to try long exposure shots. what type of filter should I get? nd grad, nd, or polarizer. I use the 18-55 mm kit lens which will rotate the barrel during autofocus. please help me.
....there's hardly any UV leaving the lens to the sensor due to the coating of lens elements.
Yes and you'll note that lens ALREADY has a "Vitacon" UV filter.
Also, do note that we need to be specific about UV-A, UV-B, UV-C, etc...
Actually, lenses still let UV light through... it is the modern digital sensor that doesn't get affected much..
UV conversion for Dslr does exist. I would think that digital sensors are UV sensitive. It may be the 'filters' just right in front that blocks certain spectrum.
I refer to a statement in the Newbie Guide to Filter - However modern digital sensors are not affected by UV light.
In the right perception, it may be correct as this may apply to IR as well.
Yes, it is mostly the UV cut properties of the glass panel(s) above the sensor. But for the sake of newbies, we usually refer to the entire sensor assembly as "the sensor". UV light affect image quality is also less of a concern because UV is often captured as blue on a sensor, and digital sensors are relatively a lot weaker at the blue end of the light spectrum.
Also, on a conventional DSLR with conventional lens, most of the UV wavelengths up to around 310nm will already be greatly reduced by optical glass in the lens. a UV filter will be able to further reduce wavelengths from 310-380nm
One also need to be clear of what kind of UV photography we are talking about. Most common is actually UV-Florescence which begins with a UV excitation source that stimulates the flourescence of a material. This means that light is re-emitted at a longer wavelength after being stimulated by UV light. This kind of UV photography does not require special equipment, but some camera models with a wider wavelength response will work better (usually 380nm and above). Do note that due to the longer wavelength, most of the light captured is actually close to or in the visual spectrum.
For reflected UV photography, there are specialized lenses used (like quartz or calcium flouride based optical elements), or long exposures in darkness are needed, apart from modifying the sensor's filters. But Reflected UV photography is mostly used in commercial or research purpose. And they usually have specialized equipment for it.
Yeah, means I read that correctly.
Is your source of UV in any way comparable to the sun in terms of intensity?
I will not stop you from doing this. Do what makes you feel happy and protected.I beg to differ.
