Exposure time, aperture and ISO value

Today we talk about some settings on digital camera(can be aplied on film camera of course). First we talk about ISO value, if that value is bigger, than image will be more noisy. Ideea is to keep that value on the lower degree! To show you difference I use Canon EOS 400D, same image, first with ISO 100 and second with ISO 1600
ISO 100
ISO 100; Exposure 1/100 sec F16

ISO 1600
ISO 1600; Exposure 1/1250 sec. F16

So.. if we use a low Iso value image will be more clear ( not in that exemple - it not was focused right :P ). But in the same time we need a long exposure time, in that case, the light was enought , so i don't need a tripod, but sometimes we need a tripod. Noise can be reduced with some software, but.. not complete!
Now, exposure time...well, here is a trick, depending to light we use a big, or a lower exposure time. Digital camera have an indicator.
If indicator is on O that mean right exposure value, if is in right image is "burned" or over exposed; if it's in left image is under exposed.
Good exposure
good exposure
Over exposed
over exposure
Under exposed
under exposure
Aperture value give the depth of image, if aperture have a low value, that mean we have a big aperture. That mean F5,6 is bigger than F32. Big aperture give a low depth of image; low aperture, a big depth.aperture F20
F20

Aperture F5
F5

So, low aperture value mean first plane clear and background blur and a short exposure time, and big aperture value results a more clear background and first plane too but big exposure time.
Sorry if you don't understand! English in not my default language! Feel free to ask!

Another way to convert Black&White images

This is an update to Dinamic black and white images! entry. Now we use chanel mixer to transform a color image to B/W one. I choose that image:color train
We add a new adjustment layer and select chanel mixer (Layer-New adjusment layer-Chanel mixer). Select monochrome and set value for every chanel (RGB) in that way you can specify how many of each channel you want in the black and white image.
Watch difference!
Desaturate

desaturated train
100% Red (0% green 0% blue)

red 100
100% Green ( 0% red 0% blue)

green 100
100% Blue(0% red 0% green)

blue 100
It's like we use a color filter on a camera!
- Red filter ligntnes Red, Magenta and Yellow and darknes Green, Blue and Cyan
- Green filter lightnes Green, Cyan and Yellow; and darknes Red Blue and Magenta
- Blue filter lightnes Blue, Cyan and Magenta; and darkness Red Green and Yellow
- Cyan filter lightnes Cyan and darknes Red
- Magenta filter lightnes Magenta and darkness Green
- Yellow filter lightnes Yellow and darknes Blue.

Think at what filter do, experiment and you will have a more nice photos! I don't say my pitures are great, but some people understanding what I write about that, will can say "I am better than you!" So... good luck!

Remove noise

Maybe the easyest way to reduce noise is to go to filter-noise-despeckle in photoshop. But let's try something new.I chose that image, a crop from "Falling from the edge of universe".neprelucrata
OK let's convert image to Lab color, go to image-mode-lab colors. Then go to chanels tab and select chanel a, then go to filter-blur-gausian blur and set value to 5 px. Do the same thing with chanel b. Ok, now select lightness chanel and aply filter-noise-despeckle!
Convert image to RGB ( image-mode-RGB color) and that's all. So.. let's see the diferrence!
lab colors
This is in Lab Color noise reduction

Acele Morarului

Located in Bucegi Mountains, "Acele Morarului" ( Miller Pins) is a very nice alpine route. You can start the route from Omu Chalet and after a nice climb over that summits you can come back on Omu chalet, or descent to Morarului valey or Cerbului Valey to Busteni city.Acele Morarului
Behind, we see Piatra Mare ( Big Stone ) Mountains, where we have some nice waterfalls inside canyons! I will post some images from there soon! If you want more infos, just leave a message!

Can you fell the music?


This entry is just to show this effect. It's two ways to do that. If you have a DSLR camera, you can set a long exposure value and in capturing time, zoom your lens.
Other way is photoshop based, just open image, go to filter- blur-radial blur. Select zoom and play with results!

Eyes corection in Photoshop

Sometimes eyes of a person don't look so nice in a picture,also if we use flash we have a red eyes. It's time to do something! That is image.
original
First we solve a red eyes problem. We can use red eye tool or, why not try something new? Select eliptical marqee tool and select the eye.  second
Now press Ctrl+Shif+N to add a new layer, fill selection with black and set blending mode to Overlay opacity to 50%. We solve red eye problem.
Now, with magnetic lasso tool select the iris, duplicate background layer and set blending mode to screen and opacity to 50%. We have a more nice eyes.
other An extra trick is to use spot healing brush tool to clear skin imperfections, after that, I adjust shadow/highlight with 20 Highlights and 10 Shadows.
again other
On that zoom level looks strange, but the real picture looks great.

Dinamic black & white image

How we create a B/W image in photoshop? Maybe you may say, to set mode do grayscale or destaurate image. But why not try something new? As we know in digital imaging white is composed from Red 255 Green 255 and Blue 255, Black from RGB colors to 0. So... let's open a color image in photoshop. Press Ctrl+J twice to duplicate background. Reneme each layer with name Red, Green and Blue. Now Click on red layer press Ctrl +U select colorize and add value 0 for Hue and 100 for saturation. Set blending mode for this layer to screen. Now do the same thing with green layer but add 125 for hue, again, set blending mode to screen. It's time to colorize the blue layer, again press Ctrl+U set colorize and add 250 for hue and 100 for saturation. And watch the results and differences.
diferrence If you want more dinamic image, flat all layers by pressing Ctrl+ Shift+E and now press Ctrl+J twice, set blending mode for middle layer to Hard light and 50% opacity and for the top layer, blending mode to screen and 50% opacity. Again press Ctrl+Shift+E to flat layers. Now Create a new layer ( Ctrl+Shift+N) and fill with color #d6aa3f now set blending mode for this layer to overlay and opacity to 30%.soNow Go to Image-adjustments-Shadow/highlight and set 0 for Highlights and 50 for Shadow.s1
That's all! Remember to ask and try yourself! Other way for create B/W images in next entry!

Colouring a black / withe photo in photoshop

I have a picture , a B/W one. So I try to create a color one from it.
First Step
With Magic wand tool select the sky, now select gradient tool with a gradient colors #3c3ccc to #b5dcfa , fill the selection.
Step two
Press W and right click on selection, select inverse, now we go to Image-Adjustments-Variation and we play with colors to create a real look for image.

original
Well...that's all!
In fact here I colorize snow with green, but, I use that to understand how you can colorize a B/W photos. Sometimes you will need to create different layers for each element. For exemple a portret, you will create a layer for skin, another for eyes, other for hair and much more ( clothes, lips) If you don't understand something, just ask! I will help you how much I can!
