2. An approach to keep you In Stitches… Presented by N. David King

3. Panoramas and Mosaics –“It seems to me indispensable that we, the creators of our own time, should go to work with up-to-date means.” Lazlo Moholy-Nagy Lazlo Moholy-Nagy © N. David King

4. Panoramas and Mosaics Definitions: Panoramas Vs. Mosaics –Panoramas Goal is a wider but nominally undistorted view Frames are usually on a single row side by side –Mosaics (Multi-Row Panoramas) Goal is increased resolution of normal view Frames are side by side AND multiple rows Also used in “immersion” photography –Both… Need a panoramic/spherical panoramic tripod head Need to be shot with exactly matching frames in terms of camera settings © N. David King …..

5. Panoramas and Mosaics Panoramas:Goals –Present a Wider View of the Scene Convey the sense of expanse Convey the sense of expanse To better compose to emphasize the subject –Avoid the overtly distorted look that comes from extreme wide-angle lenses –Can make large images rivaling prints from large format panoramic/banquet cameras. © N. David King …..

6. Panoramas and Mosaics Mosaics: Goals –Capture as much detail and visual information as possible; exceed human vision capabilities –Avoid the overtly “digital” look that comes from over-sized and over-sharpened files –Produce large printed images rivaling prints from large format cameras. © N. David King …..

7. Panoramas and Mosaics Workshop Approach –The presentation will focus on MOSAICS because a Panoramic photo is simply a single row mosaic. Consequently the basic Panoramic image is easier and quicker to assemble. If you can do a mosaic you can do any panorama. © N. David King …..

8. Concept for Multi-Row Panoramas (Mosaics) How much EQUIVALENT Resolution can we get? © N. David King 8.2 megapixels x 21 frames = 172 megapixels / less 10-15% overlap = 150 Mp+/- Or… similar to shooting with a 100mmx60mm, 150 megapixel sensor

9. Concept for Multi-Row Panoramas (Mosaics)? How DOES IT COMPARE TO FILM? (using 2006 technology) © N. David King Film Grain clumping diminishes resolution so at these sizes the chart somewhat understates the comparison of grain-free digital files from DSLRs

10. Workflow for Multi-Row Panoramas (Mosaics) The Basic workflow: –GETTING PROPERLY EQUIPPED –TAKING THE SHOTS –PROCESSING THE FILES –ASSEMBLING (STITCHING) THE IMAGE –POST-ASSEMBLY/PRE-EDITING WORK: (Flatten), De-distort, Crop, Fix Seams and blending joints –PROCESSING/EDITING THE STITCHED IMAGE –PRINTING THE IMAGE. Let’s take a quick look at each step in the workflow… © N. David King …..

11. Workflow for Multi-Row Panoramas (Mosaics) The Basic workflow: Equipment –GETTING EQUIPPED Tripod and remote/cable release Spherical-Panoramic Head Lenses –Primes v. Zooms –Brand issues Finding a Lens’s “Nodal” Point. Let’s look at each in detail… © N. David King …..

12. Workflow for Multi-Row Panoramas (Mosaics) The Basic workflow: Equipment –TRIPOD & SHUTTER RELEASE Get the sturdiest and most easily useable tripod you can afford and which you will be willing to take with you. The Tripod must be easy to level on all terrain yet hold that position with considerble weight cantilevered off axis at times. The Remote/Cable Release lets you trip the shutter without moving or shaking the camera or tripod/head –You can also use the self timer set to 3 or more seconds … © N. David King …..

13. Workflow for Multi-Row Panoramas (Mosaics) The Basic workflow: Equipment –SPHERICAL-PANORAMIC HEAD Allows movement around the lens’s nodal point on all axes. This eliminates perspective/spatial relationship changes between frames. Made by Kaidan, Bogen, Panosaurus, etc. or can be self made. © N. David King …..

19. Workflow for Multi-Row Panoramas (Mosaics) The Basic workflow: Equipment –Lenses Primes vs. Zooms Primes vs. Zooms –Resolution Potential, –Focal length slippage between shots, –Lens’s “Sweet Spot” (or spots). © N. David King …..

20. Workflow for Multi-Row Panoramas (Mosaics) The Basic workflow: Equipment –Lenses, Continued Finding the Lens Nodal Point (its Optical Center) (Exit pupils and “H” points) Finding the Lens Nodal Point (its Optical Center) (Exit pupils and “H” points) –Why bother? Perspective issues –Usually at or near the aperture/iris ring but sometimes not even in the lens body –Testing for it © N. David King …..

21. Workflow for Multi-Row Panoramas (Mosaics) The Basic workflow: Capture –TAKING THE SHOT PICK YOUR SHOT: ANALYZE SCENE & INTENDED SIZE FOR NUMBER OF FRAMES NEEDED CHOSE PROPER LENS FOCAL LENGTH SHOOT Let look at each in depth.. © N. David King …..

22. Workflow for Multi-Row Panoramas (Mosaics) The Basic workflow: Capture PICK YOUR SHOT –Identify the proper Scale/size of Final print… –Assess the Need for fine detail to tell your subject’s “story” or present your “vision” © N. David King

23. Workflow for Multi-Row Panoramas (Mosaics) The Basic workflow: Capture How Many Frames Are Needed? –How many Frames are needed will be based on either the final print size needed and/or amount of detail you desire to capture. © N. David King

24. Workflow for Multi-Row Panoramas (Mosaics) The Basic workflow: Capture How Many Frames Are Needed? –If Based on desired final print size, it means a little math is in order… Final Dimension = pixels/resolution For Example 10 inches Wide = 3,000pixels/300ppi © N. David King …..

25. Workflow for Multi-Row Panoramas (Mosaics) The Basic workflow: Capture How Many Frames Are Needed? If based on Desired Detail, it requires some experience… In my experience with 8.2mp*: 18-21 frames matches any large format camera. 24-27 exceeds human eye’s capture resolution and becomes “Hyper-Real.” –(* Using Carl Zeiss Primes for Hasselblads on Canon 20D) © N. David King …..
