Camera Raw and DNG Format Camera Raw: A file format for unprocessed image data directly from a camera sensor. DNG (Digital Negative): Adobe's open-source raw file format, preserving raw data but offering better compatibility and smaller file size than proprietary raw files. Difference: DNG is a standardized, more compatible format than Camera Raw. Both retain maximum image data but have different usability across software. Bits and Bytes Bits: Refers to the number of colors or shades per pixel. More bits = higher image quality and color depth. Bytes: Data storage unit (1 byte = 8 bits). Higher bit depth leads to larger file sizes. Dynamic Range The range between the lightest and darkest parts of an image. Higher dynamic range means more details in shadows and highlights. Affects exposure and tone control. Color Theory: CMYK vs. RGB CMYK: Cyan, Magenta, Yellow, and Black (used in printing). RGB: Red, Green, Blue (used in screens and digital devices). Difference: CMYK subtracts light (subtractive), while RGB adds light (additive) to create colors. RAW vs. DNG RAW: Proprietary uncompressed image format with maximum detail. DNG: Open-source, compressed version of RAW with more versatility across programs. Importing Images into Lightroom Ensure the correct file type and organization (folders, metadata). Apply presets during import if needed. Lightroom Masking  Masking Tools: Adjustments for specific areas (e.g., gradient, radial filters). Use for targeted exposure, saturation, or sharpness adjustments. Camera Raw Adjustments in Lightroom Adjust white balance, exposure, contrast, and other basic settings within Lightroom's Develop module. Reading Histograms (0 to 255) Histogram: Visual representation of the tonal range of an image. 0-255 scale: 0 is pure black, 255 is pure white. Clipping indicates loss of detail in shadows or highlights. Color Spaces: AdobeRGB1998, sRGB, and ProPhoto sRGB: Standard color space for web and digital. AdobeRGB1998: Larger color gamut, used for high-quality printing. ProPhoto: Even larger color gamut for professional-grade editing and printing. Resolution and DPI (72ppi vs. 300dpi) 72ppi: Standard for web images (lower resolution). 300dpi: Standard for printing (high resolution, high quality). Lightroom Modules: Library and Develop Library: Organizes, rates, and tags photos. Develop: Where edits and adjustments are applied. Histogram Clipping Triangle Indicators in Lightroom Black Point/White Point: Triangle indicators help adjust exposure to avoid clipping. Exposure Clipping: Shows if image data is lost in highlights or shadows. Clarity Tool in Lightroom Adjusts mid-tone contrast, giving images a crisper or softer look. Masking Tools in Lightroom Masking: Local adjustments for exposure, color, clarity, etc.  Tools: Graduated filter, radial filter, adjustment brush. Difference between Saturation and Vibrance Saturation: Adjusts the intensity of all colors equally. Vibrance: Selectively boosts colors, preserving skin tones and preventing over-saturation. Color Mixer: HSL in Lightroom HSL: Stands for Hue, Saturation, and Luminance. Color Pointer: Select a specific color to adjust its properties. Lightroom Collections, Target Collections, and Shortcuts Collections: Grouping of images, helping with organization. Target Collections: Default collection to send images quickly. Chromatic Aberration Color fringing around high-contrast areas in images. Corrected in Lightroom using lens correction tools. Metadata in Lightroom Information about a photo (camera settings, date, location, etc.) stored within the file. Sharpening in Lightroom Masking Slider: Helps apply sharpening to only the edges, avoiding noise in smooth areas. White Balance Adjusts the color temperature and tint of an image for accurate color representation. HSL: Hue, Saturation, and Luminance Hue: Adjust the color tone. Saturation: Adjust color intensity. Luminance: Adjust brightness of specific colors.  Luminosity Range Refers to the range of lightness in an image. Luminosity masks help target edits based on brightness levels. Photoshop: Layers and Layer Opacity Layers: Stack images or effects non-destructively. Layer Opacity: Control the transparency of layers. Layer Masks in Photoshop Allows selective visibility of a layer by painting black (hide) or white (reveal). Adjustment Layer Masks in Photoshop Applies adjustments (like brightness, contrast) only to specific parts of an image. Painting on Masks with White/Black Brushes White: Reveals parts of the mask. Black: Hides parts of the mask. Adjust opacity and softness for precision. 8-bit vs. 16-bit 8-bit: 256 shades per channel. 16-bit: 65,536 shades per channel (better for detailed editing). Transformation Tool and Shortcut Transformation Tool: Scale, rotate, and skew images. Shortcut: Ctrl/Cmd + T. Photoshop Selection Tools Quick Selection: Paint to select areas based on color and texture. Other tools: Marquee, lasso, and magic wand. Resizing in Photoshop Change image size without distorting proportions. Use Image > Image Size for precise control.  Claw Technique Method of holding tools in Photoshop for fast editing. High Pass Filter Enhances image sharpness by emphasizing edges. Clipping Mask Restricts an adjustment or layer effect to a specific layer underneath. Smart Filters Non-destructive filters applied to smart objects for flexible editing. Lightroom Shortcut () Toggles before/after views in the Develop module. Creating Virtual Copies in Lightroom Creates a duplicate version of an image without duplicating the original file. Photoshop Shortcuts x: Toggle between foreground and background colors. d: Default colors (black/white). [ and ]: Adjust brush size. z: Zoom tool. b: Brush tool. spacebar: Pan tool. Lightroom Shortcuts p: Pick flag. u: Unpick flag. x: Reject photo. g: Grid view. d: Develop module.\ l: Lights out. f: Fullscreen.  b: Add to target collection. y: Before/after comparison.
