Getting rid of tungsten blue filter.
I've just scanned 500+ slides taken years ago on my Z1p and approx 200 must have had the tungsten filter on (Idiot me). Iv'e tried PS. Bridge White Balance. As shot. Auto. Custom but can't get rid of the blue. Has anybody got a quick fix for this problem?????????????????? CHEERS Vic.

Getting rid of tungsten blue filter.
As you've filtered out the red end of the spectrum it's hard to see how it can be put back. I would suggest lateral thinking and converting them all to monochrome. It will of course be mono shot with a blue filter and that will give you an effect similar to using "ordinary film" that was only sensit...

Getting rid of tungsten blue filter.
Thanks John. If I get no other answers then I may give that a try. I must have had my wrong head on 12 years ago. The other 300 or so are all OK and I was nowhere near any tungsten light. Thank goodness I had my then new Ist*D with me for the other 1300 or so shots. CHEERS Vic.

The actual red channel is missing completely so the best you'll get from them is a sort of two colour 'bipack' colour process reminiscent of early colour photographs such as the 1915 Kodachrome; Eastman-Kodak's first colour system (amongst others.)

John. I just tried a couple and they don't look too bad. A least better than all blue like the Smurfs. CHEERS Vic.

Getting rid of tungsten blue filter.
If they're important to you to be realistic it might still be better to rescan them. :evil: Sometimes the colour fades and they end up looking like that when scanned anyhow. If they are pretty good still, to preserve them it might be best to do them again. Sorry! Might be just as quick as correct...

Getting rid of tungsten blue filter.
Been wondering since how you managed to do 500+ scans and not notice they all looked sub-aqua?!

John K. I did notice but kept on scanning in the hope that I could do something with them. I have tried exactly what you have done but I'm not keen on the outcome. I think B&W might be the answer. CHEERS Vic.

Getting rid of tungsten blue filter.
The colour cast on these is much more than a tungsten filter. which would only give a cool look just like selecting the wrong WB on your camera. It might be worth having a look at your scanner - the red light source might just have failed. (Some scanners scan progressively with 3 coloured light sou...

Your thoughts on UV/Protective filters
Evening. Having been a photographer for a very long time, I have always fitted UV filters to my lenses, as it was always considered somewhat necessary on film, and it also helped protect the front element. However, following a discussion with another photographer, it seems that UV filters are not re...

Your thoughts on UV/Protective filters
I never use them, always use hoods, never had a problem with causing damage to the end element or the coatings. A friend lent me their 16-85mm to try, after taking quite a few shots I realized it had a UV filter on the front, I took it off. In my opinion it was better without, there was a small dif...

Your thoughts on UV/Protective filters
I tend to keep a UV filter on, Marumi or Hoya Pro, and I have noticed on one a couple of very tiny chips probably from windblown sand; also they get coated with a fine deposit of salty spray. I am more comfortable wiping the filter in the field because no matter how careful there is the risk of scra...

... but apparently sensors are receptive to the UV part of the spectrum whereas film isn’t. It's the other way round! The new kids on the block are the clear lens protection filters. UV can be seen at high altitudes so a UV filter should help cut through it and reduce the blueness. Filters aren't...

I am also firmly in the hood camp and see no need for a UV filter.. Though I wouldnt decry those that use them..

Your thoughts on UV/Protective filters
I'm an old school film shooter mainly, I always* use a good quality filter of sorts (either UV or Skylight). The only exceptions are medium format lenses that I've bought used that would require huge (80+mm) filters** - these can be more expensive than the lenses! It's not about IQ but protecting th...

Your thoughts on UV/Protective filters
A really good quality filter will not degrade the image quality, however most filters, especially UV ones, are not very good quality. I've read about people dropping lenses with filters on them and shattering the filter glass which then scratches the lens glass, thereby achieving the opposite of wh...

15-30mm filters
As we know, filter systems for the 15-30mm Are not cheap, which type have you gone for and how well does it work. Derek

15-30mm filters
I bought the Lee 150 system. As you say, not cheap, but the adapter works very well with the 15-30. You can also buy a screw-in adapter that allows the 150 system to be used with other lenses via the filter thread. A good idea if you are starting out as you can then just use the 150 system for all y...
