I have a very basic doubt on f-stops calibration to the T-stops. We are taking exposure meter readings in the f-stops ,while cutting the exposure in the lens it is T-stops. How their calibrating the f-sops to the T-stops in the lens. I know the difference between the T-stops and the f-stops. Please kindly forgive me if I have asked a silly question.

Thanks Sam,
I did the search of the site and it became clear. Though I have never done it myself, I have heard and read about shooting with unusaul print stocks and sound stock but somehow I missed (or with age forgot) the term "orthochromatic".
Cheers
Tim
Actually ORTHOCHROMATIC is sensitive to two colors they are BLUE and GREEN. All the B/W print films are ORTHOCHROMATIC.

What is the running sound level of a movie camera in decibels? From what distance is this measured? What is the recommended level for the spot recording(sound)?
I think this should be known to a cinematographer because one of the sound recordist has asked me about this.

I means , we change time developer for PUSH & at that time changing PH may be reducing contrast .
As John said,I have heard only about increasing the Time and Temp for achiving the PUSH process. When we alter the PH, developing will not be under our control.Some times when changing the Chemistry they may lead to decompose the equaliberium of the formula, they cause some color shift and even make the chemical fog,because I tried this before.
In earlier Black and White film processing some were increasing the Ph of the formula with the excess alkalis to finish the work very fast but this is not the right way. They buildup high contrast negatives.

HI... thanks for the reply... i actually want to go to pune... that is my first preference. ive given the entrance test (in which i think i fared pretty well) and now im waiting for the shortlist to come out for the interviews, which i just found out has been postponed to july/august since the current year isnt over yet. if i get in there (and im sure u know how tough it is), then nothing like it. my plan to study abroad is a backup plan in case ftii doesnt work out. and since i am making a visit to the US soon, i can visit a few schools to check them out.
what about u? r u a DP or a student? if u dont mind me asking about your background... thanks
rohini
I understood. Iam a Final year student of Film and T.V Institute of Tamilnadu(FTIT),chennai. Currently Iam working as a apperentice in a Film lab and also as AC to a famous DP here. Good Luck, I know that how difficult to get into FTII because at a time I have applied to FTII and FTIT but it turned out only in the FTIT. I found that Iam really lucky to study in FTIT.

hi, thanks a lot for the info... i would love to get in touch with u multi-diasporic... though u didn't leave me an email address to contact u on... another thing i wanted to ask was that i want to try n get in to the jan'06 semester. will that be possible? do schools do that? i was hoping my previous course and work experience might help me there. thanks a ton for any help i get...
rohini
First of all Why are you trying your studies in abroad? I think that Film and T.V Institute of India, Pune is a Film school with International standard. I Don"t want to mention this,because most of the outstanding DPs and Directors are form this Institute. I think there is no difference between aboard film school and Indian film schools because in both you are going to study the same art and techniques. Even though if you study in abroad the only thing will make you different from other DPs is your personel creativity and presentation.
Good Luck.

I agree, the easiest way to restrict exposure of a particular layer is to use a saturated filter - a yellow filter blocks blue light, a magenta filter blocks green light, and a cyan filter blocks red light.
Here are the descriptions of the Wratten filters:

Thanks to all of you. since digital interemediate is more cost effective i want it to work with processing and printing methods. I need a Image like these.

Dear Dominic,
I have read most of your books. We students what to know more about only Film Processing, It should only cover about film processing, special film processing and photochemistry. Your previous books are covered about entire post production side, it was really a very valuable book.
Please give us a book which contains entire film processing techniques , you can give us this most valuable knowledge.

Is there any way to inactive a particular color sensitive layer with special processing technique. For example Magenta layer or Green sensitive layer is inactive we will get a image of two colors of BLUE and RED. While printing cut down the whole green light and print , is it possible. Iam having doubt there and never experimented on it.

Use slow speed films and use NDs for the look of DOF you wanted. Tungsten balanced film without 85B will help you in giving much Bluer look and underexpose them. Shoot most of the interior scenes in the boat during the whole day with respect to the angle of the sun. For exhibiting shot like ELS,LS there is no other choice you have to shoot in the goldern hour or in the night.
Use tungsten lamps take care that the lamps are brighter then the exterior if you commit the exterior because it should be darker then the interior.
Practice some test with your still because the producer will not allow you to make any test in the motion picture film I think.
May I know the name of the feature film, Iam a fan of malayalam films.
See wheather it works. Best of Luck.

First of all go and watch lot of HD movies and learn the lighting pattern they have used to bring down the look. I think it is the way you have to start up to learn lighting for any formatt. If you have any reading sources read American Cinematographer magazines which deal with you project you can gain up something from that I trust.
If you want to learn about Green screen technique search some previous threads in this forum which deals about that. Follow RIK ANDINOs post it is really a valuable post to the student like us because We have the responsiblilities.
First trust in yourself and you can make it. GOOD LUCK.

Always observe things around you, while walking,eating,learning,traveling etc. Nature is a teacher. Observe lightings in a coffee shop while having your coffee, even in your living room and sometime you will get new things which others were not observed. One lighting I want to share is, It is a coffee shop in the highway it is almost sun to set. The sun was directly hitting the mirror in the shop the whole shop was fill with yellow light reflected from the mirror. The vehicles which were passing in the highway were blocking and opening the sun. So it created something like flickering effect in the shop. It was really a beautiful scene.

thanks a lot Mr.Bob. sorry i should have mentioned whether it was day or night.
i have heard that if a rain is back lit...then the artist in rain might not be clearly visible.is it true. thanks.
raj
Back light the rain so that the drops will sparkle. I think that when you specified it has a Song sequence so it is Day. Choose angular sun to shoot and add fill to artist with ARRIsun so that it can match your daylight even silver reflectors are enough I think. For back light use mirrors so that they can provide you a more specular reflection for the back light.

Add grains to the image by push process and also go for some odd angles to compose. DoubleX is a good choice for push process.

Dear Freya,
Since you told that they are old stocks be aware of the previous storage properties. Some old stocks are still in good condition when their are stored in proper maintanance. First do a fog test. Films should be stored in a very cold temperature,It should be 0- -10degreeF. Store in frost free freezer.
Before going for the shoot take the film form the freezer in advance and leave to reach the room temperature , don't open the cans before this, because it will form moisture content and spotting in the film. Don't heat the cans with any heater to make them warm. Film should always be stored in a very cold temperature.
just go through for futher infomation in kodak,

I wonder if I can do any home processing? I don't know anything about D76 processing. That is new to me.
jack
Dear Jack,
First take different exposure test and developing tests if you are going to try this in home processing. Just shoot some with your Still camera it is a best way to practice i think. Developing with D76 is a good Idea and develop it for different time so you can achive its actual density. Actually when you develop this with D97 you get a very contrasty image.

Dear Jack,
First of all the main problem in exposing the sound negative is the differ in the perforation pitch, they are not curved pitch. They are very high contrast films so their stright line portion is very steap, from this we are understood that the exposure is very critical. We need lot of lights to expose this so daylight is the good source due to the very very fine grain emulsion.
Since it is a orthocromatic emulsion we loose the RED color images as black. I have exposed ST 8D and 2378E of Kodak. These films are very useful in title making, I think that they are better then B/W print films in sharpe.
These films are made for the SOUND recording so they are desinged only for this purpose. When we have to experiment we can do ,but we have to sacrifice some usual image formation. A different image is produced.

Dear John,
May I follow this blue tint for the future printing works, or it will cause any difficulties? Is it recommended to print like this?
L.K.Keerthibasu

Dear John,
Is only the lights values are producing these blue tint in the color print? Will others factors like developing, and temperature can affect them? One more doubt, I have printed a negative with slight bluish tint in it, while projecting it is looked totally like a perfect B/W print from a B/W print films. What is the reason?
L.K.Keerthibasu

If you really want to play with the contrast try to shoot with PRINT films and SOUND negative. I have shot some with them ,they are really contrast. I have exposed sound negative 2378E the lighting was very critical. Mostly I exposed that in the daylight.

Now if only you had used FILM! ;)
Videotape can have problems with very high humidity, and electronic circuits don't like it really hot. Perhaps a component in the color processing circuits is changing value with severe heating?
Are you using tape certified for SVHS? Does anything change when you record in VHS mode?
Dear John,
Sure Iam using only the certified SVHS tapes for recording.
Yes,only the electronic circuits are making the problem. We had found it and after that we have shooted only in the early morning and evening for the exteriors.
Thanks to all,

Dear David,
Iam shooting this Music Video in SVHS. We are having the problem like the images are all in total greenish but this is not happend before. we checked that whether there is a problem in the sensor but they are good in the interior. It is realy supprising to all of us.
Then we found that this only because of the heat. Is this happened before to any user here.

Dear David,
I am going to shoot a music video next week. It is very hot here due to summer and my friends are advicing me not to shoot in this high temperature, because this hot temperature will lead to color miss match. Most of the shots are in exterior daylight. Is that true,what are the precautions to be taken while shooting. Iam awaiting for the reply.

Hi I am from Chennai, India. Doing my Pre-Final year in Information Technology.
Can anyone suggest me Film Schools in India to do Cinematography and can I get the website for Satyajit Ray Film Institute of India.
Dear friend,
Iam from Film and T.V Institute of Tamilnadu, why don't you try in our institution?
What made you to find other film institutes then this one? I will provide you Informations regarding our institution If you please. I think that you know about our institution which is one of the outstanding film institute in India., Iam very much proud to say that.

Shooting 2393?
in Film Stocks & Processing

I think that exposure is critical because you can shoot this only in the very bright sun to expose normal. The ASA may be 3 or 5. The print perforation will make some problems due to the pitch.
