DEVELOPING FILM 8 STEPS
- 1 MIN H20 SOAK- AGITATE
- DEVELOPER 9 MIN AGITATE FIRST 30 SECS~ THEN 10 SEC OF 1ST MIN THEREAFTER ( DUMP IT)
- STOP BATH= 30 SECS AGITATE CONST. (RECYCLE)
- FIXER= 5 MIN AGITATE SAME AS DEVEL. ( RECYCLE)
- RINSE H20 FOR 1 MIN.
- HYPOCLEAR= 5 MIN AGITATE GENTLE SAME AS DEVELOPER
- H20 FINAL WASH 10 MIN GENTLE MOVEMENTS
- PHOTO FLO 30 SECS BATH OUTSIDE
FILM DEVELOPING IMPORTANT FACTS
TAP BOTTOM TO DISLODGE BUBBLES LOAD FIM IN TOTAL DARKNESS EACH REEL USE 10 0Z OF SOLUTION TEMPERATURE IS CRUCIAL 65-75 C AGITATION MUST BE GENTLE = OVER AGITATION CAN DAMAGE FILM AND CREAT OVER EXPOSURE.
3 factors that affects DOF depth of field
- lens apperture f/stops
- distance camera/subject
- lens focal lenght
DOF
the front/back zone within which objects appear to be sharp
extending between 2 particular distances
shallow DOF
when little else BUt main subject appear sharp
great DOF
when scene is sharp from front to back
APERTURE
CONTROL FOCUS
DARK ROOM CHEMICALS
developer-1.5 minutes use tongue to move pic water - rise quick stop bath - 15 sec fixer- 5 min water leave it hypo 3 min wash outside,, squesh+ water book
developer
transform sliver halide into silver metal
stop bath
stop action of developer
fixer
removed unexposed silver halide crystals from film- makes image permanent and impervious to light
hypoclear
remove any residual fixer from film therefore reduce the washing time
photo flo
release water tension reduce spots
APERTURE
controls intensity of light into the camera
F/STOP
f/2—f/2.8—f/4—f/5.6—f/8—f/11—f/16–…
–Big apert. smal apert—
Right to left = 1/2 multiply each stop
Left to right increase 2x
maximum aperture= wide hight quality speed of lens
combine aperture/shutter= perfect exposure
essential of printing
NEGATIVES free from dust.. load shine side up image facing down
filters
start at # 2
higher or lowe contrast grade
Focusing enlarger
open aperture/adjust size of image use leans start at f/5.6 check grain focus most lens are sharper at f/8
SHUTTER SPEEDS
capture moving object
1 second is the longest
Right—-reduce amt of light entering
——Left double ammount of light entering
1–1/2–1/4–1/8–1/15–1/30–1/60–1/125–1/250–1/500–1/1000
each direction multiply by 1/2 both directions
negative
too much exposure.. film aper dense dark
underexposure bright film film developing time to long
avoid sun exposure on fim. heat destroy it
controlling motion with shutter speed
1/30 freezes motion
1/125 stops motion completely
two main ways to portray motion of a moving object
- by freezing stop movement that appears sharp
- the other is blurring the subject
waling figure= shutter speed 1/30
1/125 stops motion completely
aperture
eye of camera,
adjustable in lenses
controls intensity of light
f stops smallest
large size diameter== larger aperture in lenses
