For the past months Iam not participating in the forums, Iam really shocked when I saw the topic that you are in Illness. It is also nice to hear that you are back form the hospital to your home, You will get well soon. We are all with you John. Take care, we all will pray for your wellness. L.K.Keerthi basu :rolleyes:

what happens if we push Process the film? Will this lead to any distortion to the film. L.K.Keerthibasu

Thank you John and Dominic. I will mail after taking the test. L.K.Keerthibasu

thank you John, what are the other processing difficulties I will face if I PUSH with TEMP. Is there any difference in the image from TIME PUSHING and TEMP PUSHING. If Iam PUSHING by TIME it will wont affect the negative in longer time in the other processing solutions? We cannot change the the DEVELOPING TIME only for the DEVELOPER, because our processing plant desing is like that. L.K.Keerthibasu

We are going to push process our final student film in our film school. We are going to use 5212 and 5218. There is no way to chage the TIME of developing to PUSH the stock because the machine design is like that in our Film School. When we change the TIME of developing the time in other solutions will change. So we have planned to PUSH this in TEMPERATURE. We are going to push from 1 to 1 1/2 stops. At what TEMPERATURE I have to set for 1 stop and 1 1/2 stop? I know that If it is time It will be 3 min 40sec for 1 stop and 4min 40sec for 2 stops. We are going to shoot the test next week both for 5212 and 5218. L.K.Keerthibasu

Thank You David, I understand. I Got it. L.K.Keerthibasu

Thanks to all of you. I know that people where doing this other then in India and got satisfactory results. Here in India the cost of transfering the HD to Film is realy high when comparing to Other countries, and they are not still that much quality. So that I came to know about this. Iam just tring to test this if I get a that much result you have got that is doing here. The basic problem here in India is we dont have a Good Technical superviser in Film recording and the people cant understand what we are explaining. Dont think that Iam Blaming on others because we are suffering to bring this out. So that Instead of getting that such a poor quality for high price why dont we try this for a very lower price with the available equipments. Please Give me the technical issues which will cause and how to give the exposure. Whether I have to Expose this every shot by shot with a help of a Spot meter? Regarding the LUT how to control that?

I have Question, I think this is not new to you people? If we want to transfer a HD formate image to a Film formate. Why don't we shoot a HD image in a HD monitor with Film? Is this is Possible, If possible how to shoot this? What are the things to be cautious while shooting this? I not speaking about the quality ,accutance and reproduction. Iam new to this technique, L.K.Keerthibasu

Other then these uses I think that GREY CARD is a very good tool for the correct expsoure. Cinematographer can judge his exposure is correct or not, here Iam not taking about the color correction but about the negative density. KODAK GRAY CARD PLUS is a well calibrated 18% gray card, only with this I have learnt about Exposure. Apologise if Iam out of the topic. L.K.Keerthibasu

Thank you FKP-1. That really helps me. L.K.Keerthibasu

May i know what is the spot angle of Nikon N80, because Iam in search of that camera. I know the Spot angle of N70 and N90 it is 3.44degree. But these camera are outdatedand not in sale at present. So Please kindly help me in Giving information about this OR any one who is like to sell these cameras. Any other camera which is Close to this Spot angle from 1 to 4 degree. Sorry to ask these type of still camera questions in this most esteemed website. Forgive me for asking that. L.K.Keerthibasu

To learn it deeply please go through "Practical Sensitometry" by Wheeler and "Motion picture cameraman's handbook" by Russel Campbell L.K.Keerthibasu

Dear James, The basic book about the Cinematography Composition is "5 Cs of Cinematography" by Joseph V Mascelli. That was a frantastic book about grammar of Cinematography composition , camera angles,cutting,close-upand continuity. There is no other way other then practice and creativity. These will be just a guide to improve our knowledge but they dont teach us Creativity. L.K.Keerthibasu

Hi, There are possiblities to do like exposing with a color negative and print in color positive and develop the color positive in a B/W contrast developer for the required product gamma. As I have done this test and got it , try it. Look what others tell. L.K.Keerthi basu

"Lighting for Film and Television" by Gerald Millerson L.K.Keerthibasu

Thank you, As you said about I read Adams "The Negative","The Print" and "The Camera" they were really precious books to the cinematographers and photographers. Actually Iam Collecting Notes and information on the Internal Parts , Mechanism and the Working Principle of Spot meters in digital also. Please helpme in knowing this information in weblinks or guide me with some referrance in books, If you include Color temperature meters also I will be really grateful to you. L.K.Keerthibasu

dear friends, Can you please provide me any web link to learn about the working principle and the operating technique of SPOT METERs. L.K.Keerthibasu

Thank you Mr.David,Mr.John and Mr.Dominic, Actually the director has decided this after shooting the project, thats why Iam asking this. I know this is a painful work. I will put tests on your suggestions. Thank you once again. L.K.Keerthibasu

What I found in this is the Sharpness of the Image becomes soft when you scan and record back to film comparatively . It is better do that in Photochemical. L.K.Keerthibasu

Thank you Mr. David, Iam actually trying to bring this effect in my project work which was shot in the total daylight. My expectation is to bring the negative to a gamma of 2.1 to 2.4 from 0.55 without the colors desaturated. The look should be a compressed tonal reproduction in the midtones. I have tested with the Bleach bypass but the colors are desaturated. L.K.Keerthibasu

Thank you Mr. Dominic and Mr. David. I still have a question ,what is the way to bring the negative very contrast? I don't want to do this in lighting the scene. Is there any possiblities to do this in developing(color negative)? A contrast look like a picture photographed as that in a pan sound negative. L.K.Keerthibasu

please forgive me, I dont think that Color negatives are possible to under expose 3 stops, are they same as that as the original scene when they corrected for normal print. I believe that the shadows will be reproduced as grainy and murky look . This is what I found with my exposure tests. L.K.Keerthibasu

I use Sekonic L398M studio deluxe, This is a good meter I have ever used Because i masted this meter so with this i had correct exposures. Its all about the way you use it. L.K.Keerthibasu

This is a basic question but I dont know whether this is a valuable .Why the contrast Decrease when the ASA increases am I right? Why this happens? Why the sound negative films are developed to a higher Gamma value like 2.8 to 3.5? In B/W motion picture films the negatives developing times are according to the ASA rating, but this not applicable in the Color films is it because of the DYEs? Iam asking this because after shooting we can alter the contrast of the film during the developing if the cinematographer desires. Why the Gamma values of both the negative and positive are fixed to a particular values? Is there any other reason other then Product Gamma? Please forgive me for asking these silly questions. Awating for the reply, L.K.Keerthibasu

Yellow-Green 11 and Green 13 are the ideal filters to render the skin tones with the Red 25A filter in the camera. This green filters will have their effect on the red portions of the subject so this will give a skin tone separation with the dramatic clouds by the Red 25A. Green 13 will do well on the skin tones with the High speed films. L.K.Keerthibasu
