Don’t forget to pick the eye icon on your original layer’s left side before performing on your Image. Clicking the icon hides the layer from the panel.

Crop, straighten or rotate the photo.

Before making any changes, confirm you’re working with a clean, oriented photo.

You’ll crop everything out if you find any unwanted white space (or any space that should not be there) around the edges.

How to crop your photo:

• Select the Crop icon on the toolbox (on the left side of Photoshop’s default workspace).
• Draw a replacement cropping area or drag the sides of the crop box to the specified positions.
• Click on (Windows) or Return (Mac OS) to crop the photo.

Also, You can use the Crop menu to keep your photo’s aspect ratios proportional, but as long as you’re printing your old photo.

Assessing the Image, you’re performing on will help you choose the adjustments or corrections you would like to form. Your required changes will depend upon your photo’s current condition.

Make the required adjustments to your Image.

There are two ways to try this step in Photoshop: adjusting your Image’s color and fixing its damaged spots.

Make color correction adjustments.

Old images are usually faded, but if you want to enhance the photo’s tone, color, contrast, and vibrancy, Photoshop can do these, too.

If you decide on the Image from the taskbar, you will see a menu that will offer you everything you would like for a few basic color corrections. Under Adjustments, you will see three options: Auto Tone, Auto Contrast, and Auto Color. Try these out and see if these automatic corrections deliver your required effect. If not, you’ll make these corrections.

It’s a good idea to find out how to read the histogram so that you’ll make accurate adjustments. From there, select Adjustments and use the various functions under this menu option. There are basic adjustments like Brightness, Contrast, Exposure, and Vibrance, or more in-depth change tools like Curves and Levels.

Depending on your photo’s condition, the simplest thing to try is fiddle with these different change tools to urge the proper tone, color, and contrast.

If your image features a color cast, here are a couple of steps to follow to fix the effect:

• First, highlight your duplicate layer, then click on the change layers icon under the Layers panel.
• Choose Levels from the change layer options.
• Click the dedicated tab to change your photo’s RGB (red, green, and blue) levels. An RGB menu will appear.
• Select any color options, then bring the white and black sliders to the histogram’s upward line.
• Click on the Layers panel to exit.
• Highlight your duplicate layer and change the layer, then right-click on the world and choose Merge Layers to mix both layers.

Fix the damaged spots.

This part is where it gets tricky—you’ll need an eye fixed for detail and a lot of patience! If there are any dust, stains, and other unwanted marks on your photo, you’ll use a couple of spot correction Photoshop tools: the Spot Healing Brush, the Patch Tool, and, thus, the Clone Stamp tool.

How to Use the Spot Healing Brush tool in Adobe Photoshop

• First, click on the Spot Healing Brush icon (the one that appears as sort of a band-aid) on the toolbox.
• Choose your required brush size within the options bar.
• After that, Choose between the Proximity Match, Create Texture, or Content-Aware Type options. Any of those options should work for what you’re trying to realize.
• Select the spot you want to repair, click, and drag the brush tool over imperfections during a larger area.

Patch Tool:

• Select the Patch Tool.
• Select the area you want to repair by dragging, then select Source within the options bar. You’ll also select your sample area by dragging and selecting the Destination option.
• Set your selection using the Shift-drag, Alt-drag/Option-drag, or Alt-drag/Option-drag combinations.
• Select Transparent if you would like to extract a transparent texture from your sample area or deselect it to place the sample area over the target.
• Try to adjust the Diffusion Slider to control how the pasted region adapts to its surroundings.
• Drag the pointer inside your selection, then place it in your sample or patch area.

How to reduce Noise in your Image:

• Click on Filter within the taskbar.
• Select the Convert to Smart Filters option.
• After that, click on Noise, then select Dust & Scratches.
• Using the pop-up window, increase the Radius pixels and Threshold levels in increments to understand the required effect. But, look out not to overdo it to avoid losing an excessive amount of detail.
• Click OK.
• Go back to Filter, click on Noise, then select Reduce Noise.
• Adjust the settings within the pop-up window and concentrate on the Preview box to visualize each adjustment’s effect.
