35mm uc hex

f2 shot.... what happened? the heliopan filter is probably the problem... nevertheless, it's lomo like.....

Are you using a 3rd party lens hood?

no hood was used im afraid....

 

[awilder]

The only explanation would be that it was shot wide open and underexposed a bit, exacerbating the normal falloff at f/2. I don't see how a filter would do that unless two of them were stacked.

I haven't noticed anything like that with a heliopan filter and the stock hood. If I think about it, I'll try to duplicate it. I have a 3 stop ND filter so I should be able to get wide open and blue sky. I did shoot a sky picture last Friday, but at f/11. Film is still in the camera.

What film? Like awilder said, maybe everything was going against you for this picture.

velvia 50 was used.... yup, probably underexposed coz i shot from hip.... 😛
but i like the effect.... i shall confirm this again when i load another roll of velvia...

thanks for the response....

 

[venchka]

Velvia 50 is going behind my UC-Hexanon next. I'll do some bright skies wide open.

That's not a bad picture. It's growing on me.

thx.... here's another shot @f2 with the light fall off....🙄 velvia as well....

but i dun have this problem(at least not as severe) on superia 400.... my fren
said it's probably becoz labs dun crop the slide like they do on negative
film...😕

light falloff to the edges at f/2 is quite high in these Gaussian type wideangle lenses anyway (with f/1.4 lenses it's worse) - and clearly visible with slide film.

Hmm, if vintage W-Nikkor 3.5cm f/1.8 is also a Gaussian type lens:

Maybe I should also load a Velvia roll in my rf-body sometimes...

 

[Sonnar2]

That's why so many RF photog.'s prefer B&W film... 😉

The typical double Gauss wide angle has some vignetting - but not that much.

I am assuming that you have two things going on:

1) first shot was taken against the setting sun (correct?). I am guessing that you see "natural" light fall off in the sky. Your eye doesn't see that, but a lightmeter will - try next time. This is natural "vignetting" at sun-rise (with a 21mm lens):

2) automatic digital contrast/brightness adjustment on slightly underexposed film will strongly amplify vignetting as you see in the interior shots. Have a look at the negatives and see how bad it really is.

thanks Roland, for enlightening.... i didn't know that sunset or rise has the light fall off effect... the 1st shot was taken during sunrise.... as for the interior shot, i've checked the negatives, well, they are as bad....
