Art 205 A2: Aperture, DOF, & Fcus Original RAW Shts Due: Crit Date: Requires 2 Ink Jet Prints (50 pints) Objectives: 1. T understand hw apertures like f-16 & f-22 have a large DOF r range f fcus. 2. T understand hw apertures like f-2.8-5.6 create shallw depth f field and selective fcus. 3. T use depth f field and fcus as creative elements in an image. 4. T use depth f field and fcus t help create visual emphasis. Subject / Cncept: Lk at the Depth f field situatins listed belw. Think abut subjects that take advantage f the fllwing situatins: Visual emphasis while als having large DOF. Visual emphasis while using shallw DOF. Creative fcus r Selective fcus Light: Open. Yu can use any kind f lighting yu wish. Hints: 1. Really lk at yur scene befre shting. Decide what part f the subject yu shuld fcus the lens n. Be specific, and yu will get better results. 2. Yu may need t use Manual Fcus in rder t have the desired level f cntrl. 3. Yu may want t try the A r Av mde. 4. Use a tripd if necessary t hit an aperture like f-16 and avid mtin blur. Requirements: (check as yu cmplete) Sht in Camera RAW. Sht in M r A expsure mde. Avid Mtin Blur When using hand held camera, use 1/60 r faster. Use tripd r equivalent at slwer shutter speeds. Sht a white balance test sht in each new lighting lcatin. Sht a minimum f 5 unique scenes using the categries listed lwer dwn n this handut. A scene can be based n changing pint f view, lcatin, angle, changing lighting situatin, changing cmpsitin, etc. Basically, there shuld be variety n yu cntact sheet. Bracket yur expsures using N (nrmal accrding t lightmeter), N+1 (ne stp ver), N-1 (ne stp under) bracket Imprt yur RAW files int Lightrm as shwn in class. On yur cntact sheet, I shuld see the fllwing: White Balance Device Shts 24 48 expsures n cntact sheet files including bracket and WB shts. Take 2 f the images thrugh the digital wrkflw prcess. One image will be a gd example f Shallw Depth f Field. One image will be a gd example f Large Depth f Field.
Yu will take the 2 images listed abve thrugh Camera RAW digital wrkflw in the Develp Mdule f Adbe Lightrm. Use Basic, Tne, HSL, Detail menus at a minimum Retuch as necessary in Lightrm r Phtshp.

Technical ability fr Camera RAW & Phtshp basic wrkflw.
Part 1: Large DOF 1. Sht at Least 1 Scene. 2. Pick a scene with at least 3 subjects / bjects ging ff int the distance. 3. Gals: - Get fregrund, middle-grund, and backgrund in fcus with detail. - This is very cmmn fr landscape, City-scape, and architecture phtgraphy. - Use an aperture f f-16 r f-22. F-22 is better if yu have it. 4. Fcus the lens n the subject clsest t yu in the fregrund. Part 2: Shallw DOF - Single Subject With busy Backgrund 1. Sht at Least 1 Scene. 2. Pick a scene with a single strng subject in the fregrund and varius activity r bjects in the backgrund. Use nly 1 main subject per scene. Think f busy backgrunds. Avid slid clrs and unifrm walls as backgrunds. 3. Gals: - Blur ut a busy scene in the backgrund - Have sharp fcus and detail n subject in the fregrund. 4. Make sure yur main subject is 2 t 5 feet frm the camera. 5. Make sure yur busy backgrund is at least 10 feet behind yur subject. 6. Use the widest pen aperture yu have. (f-2.8, 4, r 5.6 at the mst) Mre extreme results at lwest number aperture (f-2.8) Mre extreme results at lnger fcal length
Part 3: Shallw DOF - Multiple Subjects Ging Back Int Space (Depth) 1. Sht at Least 1 Scene. 2. Pick a scene with multiple subjects (at least 3) that are distinctly visible in the viewfinder. Have the bjects psitined ne-in-frnt f the ther ging back int space. 3. Gals: - Yu want t blur part f the fregrund and backgrund. Have a small area f fcus in the center. 4. Get clse enugh s that the subjects fill the frame. Try t be within 2-3 feet f yur subject in the fregrund. Yu will get mre dramatic results. 5. Fcus the lens n the middle subject. Use the widest pen aperture yu have. (f-2.8, 4, r 5.6 at the mst) Mre extreme results at lwest number aperture (f-2.8) Mre extreme results at lnger fcal length Part 4: Shallw DOF And Clse-Ups. 1. Sht at Least 1 Scene. 2. Find a subject that is at least 12 x 36 lng in the shting directin (36 mving back int space away frm the camera). 3. Get as clse as pssible with yur camera lens. This means, that yu shuld nly see a prtin f the pile with the camera lens. Be aware f yur minimum fcusing distance. Mst camera lenses have a minimum fcusing distance f 22-28 inches. Wide angle and macr lenses can fcus at clser distances. If yu have this equipment, try it.
4. Use the widest pen aperture yu have. (f-2.8, 4, r 5.6 at the mst) If yu have a zm lens, try zming the wide angle side such at 18mm. 5. Nte: Aut-fcus can have issues at clse distances. Yu may want t change t manual fcus fr this part f the assignment. Part 5: Yur Chice Sht an additinal 2 scenes. Yu can chse t cncentrate n any f the abve situatins, r play with Depth Of Field & Fcus in ther ways.see belw. Optinal Stuff fr Selective Fcus.If yu dare Fr the added challenge: try these techniques. In camera mving lens by changing fcus ring during expsure. Yu will need a lighting situatin that allws 4 secnds r lnger expsure time. Fcus the camera nrmally, and determine prper expsure (think rule f secnds). As yu take the picture, keep the fcus nrmal fr the first half f the expsure, and then change the fcus slightly by mving the fcus ring back and frth during the secnd half f the expsure. In camera mving lens by changing zm dial during expsure. Yu will need a lighting situatin that allws 4 secnds r lnger expsure time. Fcus the camera nrmally, and determine prper expsure (think rule f secnds). As yu take the picture, keep the fcus nrmal fr the first half f the expsure, and then change the fcus slightly by mving the fcus ring back and frth during the secnd half f the expsure. In camera diffusing image cming int lens Think f materials that are slightly transparent. These include pantyhse, Vaseline, varius fabrics, varius plastics, etc. Yu want t cver the lens with ne f these materials. DO NOT PUT ANY MATERIALS DIRECTLY ON YOUR LENS.put them ver a filter!!! Prtect yur actual lens!!! Leave part f the lens uncvered t have sme part f the image in fcus.
