Anybody know what the "Vignetting" setting does in phototravel? It's in the "Lens Filters..." option screen. I took two pics one with it set to 0 and the other with it set really high and I can't see a difference...

The pics suck anyway, because I had to resize them, but even in full size I see no difference. Does anyone know if this is a real photog term and what it is supposed to do???

Thanks!

I guess the effects of adding it in phototravel would be more apparent in a brighter/lighter environment than in a dark alleyway...

I think you're right. That picture hides it because most of the area that gets dimmed out by the vignette effect is already darker than the rest of the pic.
 
Being a total photography newb, I'll explain it in the best terms I can maybe someone else can chime in with a better explanation.

Shutter speed (the "F" setting) is how fast the little orifice opens and shuts. In action pics (photodrive) it determines how much time is represented by the picture in fractions of a second. 1/25 shows more movement, in the form of blur, then 1/600. In real life it also determines how much exposure the film gets and setting it too fast for the type of film you have will result in dark pics, too long in overexposed pics that looked washed out.

In GT4 shutter speed has little to do with exposure, there is a seperate setting for exposure. I haven't tried to see what effect shutter speed has in the night time phototravel pics with the light blurs, but in real life these should appear shorter with a faster shutter speed.

I haven't figured out what effect shutter speed has in phototravel, other than that...

Wow, GT1 taught me a lot about cars, GT4 is teaching me about cameras... Cool...

BTW Crackhoor, nice S14!

Thanks! It's a lot of fun. On topic, a couple little things: Shutter speed isn't the 'F' setting, that's aperture! You also won't see any shutter speed setting in PhotoTravel because there's no motion so it wouldn't make any difference, although the light trails in the city locations simulate a long exposure time (super-slow shutter speed). Your explanation looks good to me!
 
Cam! I didn't know that was you! I don't see you on our car forums much anymore.

We have a GT section over there, you should come back and join us!
 
Shutter speed the time taken (in seconds) before the shutter closes when taking a photo:

Use a larger value (eg 1/4) to allow light in for a longer time, in real life this technique requires a tripod, this will cause blurring of any moving objects.

Use a smaller value (eg 1/4000) to achieve sharp, crisp images of a moving subject. This will reduce the amount of time light has to enter the shutter so this will need to be addressed by adjusting the aperture.

F/stop this controls the aperture and focal length

Increasing the f/stop reduces the focal length of the lens (f4 = 1/4 of the focal length, f22 = 1/22), use this to control the amount of light allowed through the lens.

Hey dori, I didn't know that was you either! Yeah, I kind of ease back on the 240-related stuff around November when my car gets parked for the winter. It's too painful to see 240 pics from Florida & Cali when my car's buried under two feet of snow... :guilty:

But thing's are drying up around here and once the gravel's swept off the roads I'll fire the 240 up and I'll probably swing thru the forums and see what's up! 👍

(Sorry for the OT stuff)
