COLORIZE a black-and-white photograph

Hand-coloring a photograph can be a difficult process using traditional paints and traditional film photos.
With Photoshop, hand-coloring an old black-and-white image is much easier. You can use any black-andwhite
photo, called a grayscale image, and paint areas using any colors that you choose.

Before:-
1 Click Image.
2 Click Mode.
3  Click RGB Color.The color mode changes, but the image on the screen does not.
4  Click the New Layer button in the Layers panel.
5  Click here and select Soft Light.
6  Click the Quick Selection tool.
7  Click Sample All Layers in the Options bar (  changes to  ).
8  Click in an area to make a selection.
Note: You can optionally use any of the other selection tools to complete the selection.
9  Click the foreground color in the Tools panel.The Color Picker appears.
10  Click and drag the Color slider to select a color range.
11 Click in the Color Preview box to select a color.
12  Click OK to close the dialog box.
13  Press B to select the Brush tool.
14  Click here to open the Brush picker.
15  Click the soft-edged brush.
16  Press the left or right  bracket keys to adjust  the brush size.&  Paint over the selected
areas to apply the color.
17  Click Opacity and drag to the left
to adjust the color for the layer.(  Repeat steps 4 to 17 until the
entire image is painted.

The black-and-white photo now appears in color.

Smart Filter in Photoshop


To apply a Smart Filter, just follow these steps:
1. Select the layer you want to apply the Smart Filter to.
2. Choose Layer > Smart Objects > Convert to Smart Object.

3. Select a filter and apply it to the Smart Object Layer. A new sublayer will
appear below the Smart Object Layer containing the Smart Filter.
4. Apply several more filters if you want. They will be stacked below the Smart
Object Layer,


Once you’ve added one or more Smart Filters to a Smart Object Layer, you can
do several things to edit, remove, or modify the Smart Filter:
■ Click the triangle icon at the right end of the Smart Object Layer to expand
or collapse display of the Smart Filter(s) that have been applied.
■ Click the Eyeball icon next to the Smart Filters top layer to turn off the effects
of all the Smart Filters in the stack.
■ Click the Eyeball icon next to individual Smart Filters to turn on or off that
filter’s effects.
■ Click the icon at the right edge of each Smart Filter’s layer to edit the filter
options for that filter.
■ Change the order in which Smart Filters are stacked in the Smart Object
Layer.
■ Paint in the Layer Mask area of the top Smart Filter layer to modify what portions
of the image are affected by the Smart Filters. (This is similar to painting
in the Layer Mask of Adjustment Layers.) However, the Layer Mask you
create applies to all Smart Filters that have been applied to a particular Smart
Object Layer; different Layer Masks can’t be applied to individual Smart
Filters in a layer.




Using the Black-and-White Command in photoshop

 Photoshop presents a proposed default black-and-white conversion


1. Click Auto to give Photoshop a chance to analyze your image and provide a
new conversion mix.
2. If you like, you can try one of the black-and-white presets available from the
drop-down list, or you can load a previously saved preset (click the icon next
to the Preset drop-down list and choose Load Preset to select one of your own
settings mix)

3. Alternatively, you can manipulate the reds, yellows, greens, cyans, blues, and
magentas sliders  until you achieve a conversion
that pleases you. Drag left to darken that color’s tones; to the right to
lighten those gray tones.
4. To add a colored tone to your monochrome image, click the Tint checkbox
and adjust the hue and saturation sliders until you get the toning you’d like
to add.
5. You can save your settings as a new preset by clicking the icon next to the
Preset drop-down box.

6. Click OK to apply the changes you’ve made. Compare the Black & White
command conversion with Photoshop’s Desaturate command conversion



Using Merge to HDR in Photoshop


Here are the steps followed to
get the final result.
1. Set your camera up on a tripod to hold it steady for the individual shots. The photos must be
as close to identical—other than exposure—as possible.

2. Prepare to take two or three photos at different exposures times. You should vary the shutter
speed, rather than the lens opening, because changing the aperture will modify the depth-offield
and may change the apparent size of some components of the photo, such as points of light.
If your camera has a bracketing command, you can use that to change the shutter speed between
shots only if your camera allows relatively large exposure increments, such as 1 EV between
bracketed shots. Generally, most cameras bracket using smaller 1/2 or 1/3 EV steps that are not suitable
for Merge to HDR.


3. Make the individual photos at least one or two EV steps apart, such as 1/60th second for the first and
1/250th second for the next, and perhaps 1/15th second for the third. Smaller increments will provide
little extra information for Merge to HDR to work with; larger increments may create photo
sets that are so far apart in exposure that there is not sufficient overlap to produce a smooth tonal
range.

4. Save in RAW or TIFF format in your camera so you’ll get full-range, 16-bit/channel images,
rather than the 8-bit/channel images created by JPEG. However, if Merge to HDR works with 8-
bit/channel images, it will combine them into one new 16-bit/channel image using the HDR
capabilities.

5. If you use an application to transfer the files to your computer, make sure it does not make any
adjustments to brightness, contrast, or exposure. You want the real raw information for Merge to
HDR to work with. You’ll end up with two photos.

6. Activate Merge to HDR by choosing File >Automate > Merge to HDR.

7. Select the photos to be merged.


8. Once Exposure merge has done its thing, you must save in .PSD, .PFM, .TIFF, or .EXR formats
to retain the floating-point data, in case you want to work with the HDR image later. Otherwise,
you can convert to a normal 24-bit file and save in any compatible format.


Adding Clouds in Photoshop

Adding Clouds

open a photo that have sky with a mountain..then

1. Use the Magic Wand with Tolerance set to 20 and clicked in the center of the
sky. This will grab most of the sky,

2. Use Select > Similar to capture virtually all of the rest of the sky. If you see
any non-selected areas (they will “sparkle” with the selection border around
them), press Q to jump to Quick Mask mode and paint in the small dots that
remain unselected.

3. Choose Selection > Save Selection to save your sky mask.

4. Next, load the sky.jpg photo from the website. Copy the image by pressing
Ctrl + V, and, with your sky selection in the Mountain photo still active,
choose Edit > Paste Into (or press Shift + Ctrl/Command + V) to insert the
new clouds into the photo.

5. Use Edit > Transform > Scale and resize the clouds so they fit in the available
area. Notice that you don’t have to resize the image proportionately. You can
stretch in one direction or another to make the clouds fit. The “distortion”
isn’t apparent because clouds are just clouds and have no natural proportions.

6. Next, adjust the opacity of the new cloud layer in the Layers Palette. One key
to making composites is not having one object stick out because it is overly
bright, overly sharp, or overly dramatic. By reducing the opacity of the cloud
layer, the clouds will blend in with the plain blue sky underneath. I reduced
the clouds to 44 percent opacity, and they blended in just fine.

7. You may make one final modification. I returned to the original mountain
layer, loaded the sky selection, then inverted it (press Shift + Ctrl/Command
+ I) to select the mountains and foreground. I then copied that selection and
pasted it down on a new layer above the clouds. Then, I used the Smudge tool
to lightly smudge the edges of the mountains, removing any sharp line
between the mountains and the sky.


Merging Photos the Easy Way in Photoshop


Now, let’s merge the same two pictures using Photomerge, which has been considerably
enhanced for Photoshop.


1. Choose File > Automate > Photomerge.

2. Select the files you’d like to merge. You can choose the files to combine in three ways:
■ Select Files from the drop-down Use list to browse for files on your hard disk.
■ Select Folders from the drop-down Use list to select all the files in a particular folder.
■ Choose Add Open Files from the list to select from files already open in Photoshop. All the
files will appear in the center list, where you can select one or more and click the Remove button
to delete them.

3. Select one of the five Layout options from the left side of the dialog box.



4. Mark the Blend Images Together checkbox if you want Photomerge to attempt to fuse the images together smoothly.

5. Click on OK to start the process. Photoshop will examine the images and attempt to match them If it cannot, you’ll see the dialog box Click on OK, and then drag the images onto the Photomerge workspace


6. If you’re manually lining up images, each image will become semitransparent
as you drag so you can line up its overlapping area with the image underneath.
Photomerge has tools at the left side of the workspace that can be used to
move, rotate, or zoom in on the image, and to set a “vanishing point” that
defines the imaginary horizon when using the Perspective options of
Photomerge.

7. Click the Reposition Only button box on the right side of the dialog. You’d
use the Perspective choice instead if you needed to adjust the tilt of the images.
Our test images are a good match perspective-wise, so Reposition Only works
just fine.

8. Mark the Snap to Image box. This tells Photoshop to go ahead and move one
or more of the images being merged to more closely line up the common
areas.

9. Click on OK to merge the images. You’ll end up with several layers containing
each of the original images, with layer masks applied to blend them
together. You can edit the layer masks or perform other modifications to the
individual components to better match them.
10. When satisfied, flatten the image.
11. Crop the resulting image



Stitching Two Photos Together in photoshop


Tips to stitch two photos together...how to shoot first.

However, if you plan out your panorama as you shoot, you can avoid many of the
problems. Here are some tips for shooting good panoramas.
■ Minimize the number of photos you take to reduce the number of images you
have to stitch together. If you really, really want a 360-degree panorama you
can take one, but plan on spending a lot of time combining images.
■ There are specialized software programs you can buy; however, I recommend
seeing how well Photoshop works for you before buying one of these.
■ Use a tripod with a panning head as a way to keep all your images level.
Adjust the tripod (use an actual level if necessary) and swivel through your
panorama to make sure the transitions will be smooth before taking the first
photo. Some panheads and ballheads have markings in degrees to help you
align the camera.
■ Try to keep exposures, including lens opening and shutter speed, the same
between pictures so they’ll match more easily, assuming that the light doesn’t
change as you swing the camera to take the individual shots.
■ Remember to overlap your images slightly so you’ll be able to blend each
photo into the next.
■ You should know that, technically, the camera should rotate around the optical
center of the lens, not the center of the camera body to produce the most
realistic perspective. Some panorama attachments for tripods include a plate
that includes a tripod mount under the lens center, rather than in the usual
location under the camera body.
