PS photo filters Sky 1A type

Sky filters, anti-blue hue for daylight shots.
Noted* color names I have given relate to the color scale verticle
in the middle of the color picker pallet, not the actual color as seen.
Menu:
Image/Adjustments/Photo Filter
red-brown*:
FFC1A2 r255 g193 b162 (20-30%)
red-magenta*:
FFA2CE r255 g162 b206 (15%)
red-orange*:
FFB6A2 r255 g182 b162 (30%)
tan, strong:
B87E39 r184 g126 b57 (20%)
which is close to the
sepia standard filter in PS CS:
AC7A33 r172 g122 b51 (20%)
Copy and paste into a text if anyone can use them because that
pallet does not have a save option, at least in CS1. I cannot
find anything on this subject anywhere online!
Has anyone experimented with this idea? Or does anyone have
other and possibly better ideas for sky filters?

Re: PS photo filters Sky 1A type

To correct your example, I wouldn't add a filter after the fact either, but
employ (amongst other things) channel adjustments in LAB mode.
Some of the problem regarding haze also used to be due to a particular films
sensitivity (chemistry)to certain colours and its dynamic range, this is on
longer the problem with modern CCD's.

Re: PS photo filters Sky 1A type

One of the issues here is the reduction of haze in the original exposure.
Adding a color filter after the fact is not the same as making a proper
filtered exposure.

In article <sNJRg.1120$ef2.588@fed1read09>,
Image->Adjust->Curves.
Photoshop excels at extremely fine, extremely controllable color
correction--that's one of the things it excels at. If you have a blue
cast to your images, use the Curves command to get rid of it.

I am sure "Curvemeister" Mike has some pins that would be of help to
you..
the following is probably a cross post but I am gonna put it here
anyway.. 'cause I don't know any better.. I am old and slow!.. and use
Photoshop 7
If you are trying to emulate slr lens filters there is a freeware
program Opanda PhotoFilter at http://www.opanda.com/en/pf/download.htm
It includes more than 100 types of filters in it, there are all kinds of
color photo filter from Kodak/Cokin/Hoya. It's easy to use, You can
import your photo right into the software and apply the filters directly
and it saves as a copy of your picture leaving the original as it is. To
get the filters into Photoshop I loaded a blank transparent .psd picture
in it and selected the color filter I wanted, just click the "Apply"
button, the result will be shown with the filter on! After being
imported it into photoshop.. It is an easy matter to get your Pallet
Numbers with the point sampler... Or simply drag it onto the picture you
want to apply it to a mask or the whole picture or layer and adjusted
the opacity to about 50% (or whatever looks best). I don't know what
you are doing but maybe this will help.. and it is free!!
OR.... Let the Curvemeister color wizard guide you thorugh the basic
steps of color correction. Get it at http://www.curvemeister.com/
I am in no way associated with Mike or Curvemeister but his knowledge
has been very helpful to me in this forum

The Polarizer is almost a permanent fixture on my SLR... If I want
"Pink" anywhere in particular or everywhere then it gets Photoshopped

Re: PS photo filters Sky 1A type

SLR photography is no different from any other.
The filters you mention have a mild effect upon the blue caused by
light-scattering haze. They might have a very slight effect in apparent
reduction of haze. As I wrote, CS2 has PhotoFilter adjustments to 'simulate'
the color correction.

Re: PS photo filters Sky 1A type

....
[re using Photoshop to get a Sky 1A filter effect]
The best book I've seen on this is Professional Photoshop by Dan Margulis.
The overall haze is dealt with by setting a shadow point, and the blue cast
would be fixed when setting a neutral, or other reference color, during a
color correction. Blue haze in particular may be dealt with using a
specific curve adjustment in the Blue channel. Digital offers several
advantages over an optical filter: saturation may be increased, the amount
of change can be varied according to the intensity of light, and the effect
may be restricted to certain parts of the image using masks.
If you have a particular image, perhaps you can make it available online.

Re: PS photo filters Sky 1A type

Why only "SLR" photography? Fixed lens cameras also suffer from the
"problem" you describe.
Colour perspective /Spatial separation. The brain compensates, cameras
don't.
Have you tried shooting in RAW or with different white balances (cloudy in
your example)?
Shouldn't do if you are using PS correctly , adjustment layers etc.,
Maybe this is because this form of correction is no longer the problem it
used to be when using PS/digital cameras. The trouble with using any piece
of glass in front of any optic is that it can introduce other problems, loss
of quality, flare,etc., Also, any correction it provides is applied to the
whole image, not always desirable. A "pink" filter used to correct a
blue/hazey background will also affect foreground whites for example.With
PS, you can apply any correction that a filter provides and you can apply it
selectively, just to one part of an image or different strengths to
different parts of the image.
The only use for the aforementioned filters are to provide protection to the
lens front element. Saying that, I use a circular polarizer on all my
landscape shots, as I found that it is quicker to get the effect I want in
camera, than post camera.
