Will it impact image quality? Probably. Will the stacked ND filters allow you to get a shot that would be impossible otherwise? Definitely.

Has anyone here tried to stack a linear polariser on a cpl? That will give you variable ND from 1 stop to many, with the anti glare bonuses. I'm wondering if it's worth doing.

Fists Up posted:On the topic of filters. If i stack a few ND filters will it beging to affect picture quality? Yes. Inevitable, also required if you want the effect. Don't worry too much. Filters suck if they're doing NOTHING but impacting IQ, but if they're doing a job you need, well, you need it.

I've used a vari-ND for this and that poo poo is rad as hell. Especially since you can just dial shutter and aperture then you just twist your vari-ND until your exposure is correct. Too bad they're laughably expensive (reason I don't own one).

Yeh I pretty much have to in situations for video work. Trying to stay around 1/50 in bright sunlight with a shallow depth of field is pretty impossible without a stack of filters.

Fists Up posted:On the topic of filters. If i stack a few ND filters will it beging to affect picture quality? Depends on the quality of the filter. So long as it's not reducing the image quality to a noticeable point, I don't see why you couldn't do this. I mean, it's not as optimal a solution as one filter with the strength you need. But if that's what you have on hand and can get acceptable results, I don't see why you wouldn't stack the filters. The only way to know is to look at the results from your specific filters. Shouldn't be a problem as long as they're not Best Buy Sunpaks or something of similar ilk.

The downside with cheaper ND filters is that at higher strengths, they can give the photo a purplish tinge. Also it can mess with the AF system because it might not be getting enough light to focus.

Being a cheapass, what's a good DIY way to mount a reflector on an umbrella stand ? I.e. something like this but for a stand instead of a tripod.

On my EOS 500D there is a "exposure level indicator (ELI)" to make pictures brighter or darker (excuse my layman terms). When would I use this and what does it do? Is using this preferable to adjusting the ISO value? In fact, does it change ISO or aperture or both? Let's say I have a scene that is slightly over- or underexposed, would it be better or easier to change the ELI instead of other things? Thank you very much!

It is the same as 'exposure compensation' and works where you think that the camera is getting it wrong. e.g. you use the camera in Av/Tv/P and the important part of the subject is too dark. So, you dial up +1 and it makes the scene 1 stop brighter. Basically, it works when the subject is lit trickily (eg against a dark/light background) or when the scene is not a neutral mix of lights and darks. The camera gets fooled and you can adjust. Snow is a good example. The camera meter sees a lot of bright white, gets confused (cause it is expected a neutral scene) and so the picture is dark. You add +2 to brighten back again. Look for articles on 'exposure compensation' to learn more

It'll change whatever setting you leave up to the camera (shutter in A, aperture in S, both in P), which includes ISO if it's on auto. Does that make sense?

Hey I'm starting to shoot medium format in my class and I was wondering if there was a way for me to make a cheap bw filter using cellophane or something on the hood. This is probably the most retarded idea since anything not glass is going to reduce image quality and having me mess with my exposure. Edit: Or is it possible to mess with the channel mixer in any meaningful way with scanned images? Fiannaiocht fucked around with this message at 20:34 on Sep 10, 2010 |

Fiannaiocht posted:I was wondering if there was a way for me to make a cheap bw filter using cellophane  If you want black and white just shoot black and white film. Or scan the film. There is no filter that can take colored light and turn it into black and white light to shoot onto color film... which doesn't even make sense.

You could probably go to the theater department of your school and beg/steal some scrap gels from their lights. As long as you get ones that aren't scratched/punctured/melted you should be fine. Just hold them in front of the lens.

My buddy used to tech for our university's theater, and they had enormous rings of "sample" gels from companies that just happen to be the perfect size to fit a speedlite that he was more than happy to give away.

I used a third party app to perform tethered shooting in Lightroom 2.. apparently LR3 can do this better. Anyone used LR3 for tethered shooting? edit: Gah, Nikon D80 isn't in their list of tether capable cameras.. Wonder if I can get around this.

Has anyone had any experience with cheapy eBay optical triggers? How sensitive are they? Do they need to point straight at the flash, or is anywhere ok? And can they trigger through windows / around corners?

Lack of support sounds weird, but I have a 450D which works so I don't know  It's a pretty basic feature, auto-saves images as they're taken to a specified location. It's nice to preview pictures in a larger screen as it will always show the last picture captured, but it takes a few seconds for each transfer - I guess that might be normal though.

This is most likely a retarded question but my google skills fail me. When viewing a picture in Photoshop and paint it has nice details and looks ok. But when viewing it in windows photo viewer or uploading it to flickr it looks like some of the colors have disappeared...  Bad left good right but the same thing happened here with this picture. So... What am I doing wrong?

I have used it but it's super basic and not really ready for real shoots yet. God help you if it decides it doesn't want the camera to connect because there's not really anything you can do about it except restart LR/reboot and pray it picks it up. I hope they make some big improvements to it because Capture One needs the competition. quote:Being a cheapass, what's a good DIY way to mount a reflector on an umbrella stand ?
