## **1. What is Photography?**  

Photography is the art and science of capturing light to create images. The word comes from the Greek *photos* (light) and *graphé* (drawing), meaning "drawing with light."  

A photograph freezes a moment in time, preserving emotions, landscapes, and stories. With advancements in digital technology, photography has become more accessible, but mastering it still requires knowledge and creativity.  

## **2. Key Elements of Photography**  

### **A. Light**  

Light is the foundation of photography. The quality, direction, and intensity of light dramatically affect the mood of an image.  

- **Natural Light** (sunlight, golden hour, blue hour)  

- **Artificial Light** (flash, LED panels, studio lighting)  

- **Hard Light vs. Soft Light** (harsh shadows vs. diffused light)  

### **B. Composition**  

Composition refers to how elements are arranged within a frame. Strong composition guides the viewer’s eye and creates balance.  

- **Rule of Thirds** (dividing the frame into a 3x3 grid)  

- **Leading Lines** (using lines to draw attention)  

- **Symmetry & Patterns** (creating visual harmony)  

- **Negative Space** (using empty space for emphasis)  

### **C. The Exposure Triangle**  

Proper exposure ensures a well-lit image. Three key settings control exposure:  

1. **Aperture (f-stop)** – Controls depth of field (blurred vs. sharp background).  

   - *Low f-number (e.g., f/1.8)* = Shallow depth of field (portraits).  

   - *High f-number (e.g., f/16)* = Deep depth of field (landscapes).  

2. **Shutter Speed** – Determines motion blur or freeze action.  

   - *Fast (1/1000s)* = Freezes fast movement (sports).  

   - *Slow (1/30s or slower)* = Creates motion blur (waterfalls).  

3. **ISO** – Controls sensor sensitivity to light.  

   - *Low ISO (100-400)* = Less noise, ideal for bright conditions.  

   - *High ISO (1600+)* = More noise, used in low light.  

### **D. Focus & Depth of Field**  

- **Autofocus (AF)** vs. **Manual Focus (MF)**  

- **Shallow DoF** (isolates subject) vs. **Deep DoF** (everything in focus)  

### **E. Color & White Balance**  

- **White Balance** adjusts color temperature (warm vs. cool tones).  

- **Color Theory** influences mood (e.g., warm tones for coziness, cool tones for calmness).  

## **3. Types of Photography**  

Different genres require unique techniques:  

- **Portrait Photography** (capturing people’s expressions)  

- **Landscape Photography** (scenic views, nature)  

- **Street Photography** (candid moments in public)  

- **Macro Photography** (extreme close-ups of small subjects)  

- **Wildlife Photography** (animals in natural habitats)  

- **Product Photography** (showcasing items for commercial use)  

- **Event Photography** (weddings, concerts, sports)  

## **4. Essential Gear for Photographers**  

- **Camera** (DSLR, mirrorless, or smartphone)  

- **Lenses** (wide-angle, prime, telephoto, macro)  

- **Tripod** (for stability in low light)  

- **External Flash/Lights** (for controlled lighting)  

- **Memory Cards & Backup Storage**  

- **Editing Software** (Adobe Lightroom, Photoshop, free alternatives like GIMP)

## **5. Post-Processing & Editing**  

Editing enhances photos by adjusting:  

- Exposure & Contrast  

- Color Grading  

- Cropping & Straightening  

- Retouching (removing blemishes, distractions)  

Popular tools:  

- **Adobe Lightroom** (color correction)  

- **Photoshop** (advanced retouching)  

- **Snapseed / VSCO** (mobile editing)

## **6. Tips for Improving Your Photography**  

✅ **Practice Daily** – Shoot in different lighting conditions.  

✅ **Study Other Photographers** – Learn from their techniques.  

✅ **Experiment with Angles** – Shoot from high, low, or unusual perspectives.  

✅ **Master Manual Mode** – Take full control of your camera.  

✅ **Tell a Story** – Think about the message behind your image.
