Pics On Very Sunny Days

Tue Sep 25, 2001 5:37 am

Hi all

This has been posted already in the aviation forum.

I have a little problem, which I hope to be able to resolve with your help.

Some weeks ago I took the following picture:

This was taken with Fuji Provia 100F bertween 10 and in 11 in the morning. The weather was very sunny and a bit hazy.

Now, while the aircraft itself is good, I have lots of problems with the sky, which turns out very dark on the scans (scanned with Vuescan).

As the rest of the scan is ok (at least in my opinion), I assume that the color must be too dark on the slide itself.

Now, what do you do under such conditions? Is there any Filter, which might help here? In some books, they talk about sky filters and such things. Any input on this?

Thanks and kind regards
Gerardo

Nice pic!

I think the sky looks ok. I always use a 1A skylight filter, it softens the colors, and protect the lense. If it is a very bright day I'll use a polarizer on top of the 1A, because it makes the colors go darker and not so washed out.
IMO you don't need to change anything, but if you do, I'd suggest brightening the photo in photoshop, you could select just the sky and adjust it to look better.

Regards,

Staffan

Wonderful though Vuescan is, it is not perfect, and it might be the contrast in the slide is beyond the parameters which Vuescan can cope with while using "shite point" or "auto balance" settings. With high contrats slides I prefer to scan with neutral settings, and then make any necessary adjustments post scan.

Cheers,

Staffan, does the 1A skylight filter change the colors in any way? And how much f-stops will cost that?

Colin, I prefer Vuescan in about 80% of the times, but sometimes the original Minolta scan software brings better results. BUt what do you mean with "neutral settings"? Do you make a raw scan in that case?

Thanks for the answers so far.

The 1A will soften the colors a little, and take away the blueish tone that a white surface would get from the UV light. Don't think it affects the aperture.

Hi Gerardo,

If you feel you only want to brighten the darker areas, try increasing the gamma setting (in Vuescan) to something above 2.2.

I use 2.2 pretty much all the time (brightness 1.3) for KR64 and this works great...but to brighten darker areas when the aircraft is already well lit I might take the gamma up to 2.6 or even 2.8.

Using the "Preview Mem" feature of Vuescan this is quick to test...so experiment and see what works for the shot.

Good luck!
Dean

Every time I read an update on this thread, I keep wondering what the problem is with the sky on this pic. Personally, I'd far rather have a nice blue sky than a washed out white one - indeed, if the circumstances were right, I'd even add a polariser to deepen the blue in a sky.

Good tips though Dean!  Big grin

Andy

Gerardo - under the "colour" tab in Vuescan there are a range of setting which determine how the scan exposure is made ... normally I would use "auto balance" or "white balance", but with contrasty slides, the "neutral" or even "none" settings seem to give a better result ... often too flat for normal slides though.

If the color tab means nothing to you, perhaps you have an old version of Vuescan - the controls have been re-organised in more recent releases. I think I'm on 7.1.12

cheers,

Yiehaa! Thanks very much for the answers so far.

Andy, the proble I have with the sky, is, that it isn't as blue as I saw it with my eyes. On that pic, I already manipulated the sky a little bit. The first scan showed a snow white fuselage, but a dark sky between dark blue and grey. I have such pics often when I shoot under those weather conditions, that's why I asked, if the pro's here know, what to do.


Garry, it is maybe a personal thing, but I prefer the beautiful, really blue skies, you know, the "caribbean holiday" ones  Smile/happy/getting dizzy. The haze just gives a dark background as a result.


Dean and Colin, thanks very much for the hints about Vuescan. I still have some slides of that same day to scan. Let's see, what happens.

Regards
Gerardo
