> ?? Mainly used in portrait photography but works great
for
> meteorites.? It is used to reflect soft light onto the
> subject(meteorite).? I use it to fill in the shadows
> because sunlight can make highlights and shadows harsh.?
> I have a 5-in-1 reflector made by promaster.? They
usually
> run about $35 because you are paying for 4 different
> reflectors and a diffusion screen.
>
> The second thing is custom white balancing.? Have you
ever
> taking pictures in the shade or inside and the picture
> came out way too yellow or too blue?? This is because
the
> auto-white balance on your camera didn't do so well.?
Many
> digital camera's(Most SLR's) have a custom white balance
> setting.? Just simply hold up a white sheet of paper in
> the light you will be shooting in and take a picture of
> it.? Then find custom white balance and select the
picture
> you took of the paper.? Now when you shoot in that light
> the picture will be properly white balanced.? This is a
> life saver for Nikon shooters because Nikon has terrible
> auto white balance.
>
> The third thing is auto-blending.? For those of you who
> have SLR's you will notice that shooting at a higher
> F-stop like F1.8 or F2.8 is a lot sharper than shooting at
> a lower F-stop like F22.? The problem is, you might have
> to drop your F-stop to make sure the whole meteorite is in
> focus.? Fortunately, photoshop can take a batch of
photos,
> align them, and then blend the sharpest plains of focus
> into one picture. To do this set your camera on a tripod
> and set it to Av(aperature mode) spin the wheel to drop
> your F-stop to as low as you can get it. Some lenses only
> drop to F3.5 which is still fine.? Then switch your lens
> to manual focus.? Focus until just the front part of
your
> meteorite is in focus and take a picture, then keep taking
> pictures as you change the focus in small increments.?
You
> should end up with 5 to 10 pictures with different parts
> of the meteorite in focus.? Open photoshop and the go
> File>Scripts>Load Files into Stack... Select all of the
> photos and be sure to check the box that says "Attem pt To
> Automatically Align Source Images. Select ok and let
> photoshop align the images.? Then go under the tab
> "Window" and make sure "Layers" has a check next to it.?
> The layers box should be on the right side of your screen.
> All the pictures will be listed under layers. Select them
> all.? You can do this by holding ctrl key and clicking
> each one or click the first, then holding shift as you
> click the last.? Once they are all selected go to the
> "Edit" tab and select "Autoblend layers" and choose to
> autblend them as a stack. Once it is done blending you
> need to click "Save as" and save it as a Jpeg because it
> will try to save it as something else.? Then close out
of
> the image in photo shop, if it asks you if you want to
> save click NO.? Then you can open up the jpeg version
you
> saved and edit it how you like (brightness/contrast etc..)
> or leave it as is. Here is an example i made with only 5
> pictures blended:

> The fourth thing is highlight tone priority.? You can
> enable this in your custom functions for canon
shooters.?
> I know Nikon has the setting but I don't know what it's
> called. This setting will make sure that your picture's
> highlights will not be blown out.? It also allows your
> processor to use all its bits.? My camera's have 14bit
> processors but if Highlight tone priority is off the image
> only processes at 10 bits.? When i use HTP and get the
> full 14bits, this allows my picture to smooth out the
> changes in light to dark in my photos.? This makes
> everything shaded better, especially clouds!
>
> The fourth and last thing is HDR photography(High Dynamic
> Range). You do not need a SLR to do this. Most point and
> shoot cameras can do this too! Sometimes a picture can be
> too dark in one part and too light in another. If you
> take one picture over exposed, one under exposed, and one
> properly exposed and blend them together it will allow all
> parts of your picture to be properly exposed.? Here is
an
> example:
