Q1: What is Adobe Photoshop?
A: Adobe Photoshop is a professional image editing software used for photo retouching, graphic design, digital art, and web graphics. It allows manipulation of images using layers, filters, and various tools.
Q2: What is the difference between Photoshop and Illustrator?
A: Photoshop is raster-based (pixel-based) and is best for editing photos, while Illustrator is vector-based and is used for creating scalable graphics like logos and illustrations.
Q3: What are layers in Photoshop?
A: Layers are like transparent sheets stacked on top of each other that allow you to edit and manipulate parts of an image independently.
Q4: What is the difference between Raster and Vector images?
A: Raster images are made of pixels and can lose quality when scaled (used in Photoshop). Vector images are made of paths and shapes, and scaling does not affect quality (used in Illustrator).
Q5: What are masks in Photoshop?
A: Masks allow you to hide or reveal parts of a layer without permanently deleting content. There are two types: layer masks and clipping masks.
Intermediate Questions
Q6: What is the difference between Clone Stamp and Healing Brush?
A: Clone Stamp copies pixels from one part of the image to another. Healing Brush blends the copied pixels with the target area for a seamless fix.
Q7: What is the difference between Dodge and Burn tools?
A: Dodge lightens parts of the image, while Burn darkens parts. Both are used for enhancing highlights and shadows.
Q8: What are smart objects in Photoshop?
A: Smart Objects are layers that preserve an image’s original data, allowing non-destructive editing, scaling, and applying filters.
Q9: What is the difference between Adjustment Layers and Image Adjustments?
A: Adjustment Layers are non-destructive edits applied to layers without altering original pixels. Image Adjustments directly modify the image pixels.
Q10: What are blending modes in Photoshop?
A: Blending modes determine how layers interact with each other, such as Multiply (darkens), Screen (lightens), Overlay, and Soft Light.
Advanced Questions
Q11: What is the purpose of the Pen Tool in Photoshop?
A: The Pen Tool creates precise paths and shapes, which can be used for selections, masks, or vector graphics.
Q12: What is the difference between RGB and CMYK?
A: RGB (Red, Green, Blue) is used for digital displays. CMYK (Cyan, Magenta, Yellow, Black) is used for printing.
Q13: What are filters in Photoshop?
A: Filters are effects applied to an image or layer to achieve various artistic or corrective results, such as blur, sharpen, distort, or stylize.
Q14: What is the difference between Smart Filters and regular filters?
A: Smart Filters are applied non-destructively to Smart Objects and can be modified or removed anytime. Regular filters permanently alter the pixels.
Q15: How do you remove a background in Photoshop?
A: Using selection tools (Magic Wand, Quick Selection, Pen Tool) and masking techniques to isolate and delete or hide the background.
Practical & Situational Questions
Q16: How can you sharpen an image in Photoshop?
A: Using filters like Unsharp Mask, Smart Sharpen, or High Pass filter combined with Overlay blending mode.
Q17: What is the difference between Save As and Export?
A: Save As saves a file in Photoshop or compatible format (.PSD, .TIFF, .JPEG). Export is used to save optimized versions for web or specific applications.
Q18: How do you retouch a portrait photo?
A: Using tools like Spot Healing Brush, Clone Stamp, Dodge & Burn, frequency separation, and adjustment layers to enhance skin, eyes, and overall appearance.
Q19: How do you change the color of an object in Photoshop?
A: By using Hue/Saturation adjustment layer, Color Replacement Tool, or selective masking with Solid Color layers.
Q20: What is the difference between “Flatten Image” and “Merge Layers”?
A: Merge Layers combines selected layers into one. Flatten Image combines all layers into a single background layer, discarding hidden layers.
