Dear Joggie Thank you so much for taking the time to give me some good advice. Concerning ISO then I´ve always used 100ISO at Greenland due to the bright light and reflections from the snow. Nevertheless an owner of a photoshop told me that I had to use 400 ISO. Confusing when getting various statements from skilled people, but I trusted my gained knowledge and bought 100ISO film again which was good. All your info will be stored and hopefully used very soon!:-) Take care Annemette

Me again Annemette - I forgot to warn you - if you increase the ISO on your camera two things will most probably happen - The amount of noise will increase (especially in the shadow areas and more so if you are underexposing the image an also if you use long exposure times e.g. slower than 1:60th of a second) and secondly the definition of the image will also deteriorate, especially at the highest ISO setting. So please, only use the higher ISO when you want to shoot in low light conditions without a flash and keep the quality of the image in mind. An oh yes, always remember to reset the camera to a lower ISo as soon as you are finished shooting in the lower light conditions.

Hi Annemette - its a pleasure! Might take another look at your camera manual, there might be a menu setting enabling you to change the f-stop although I am not sure. Regarding contrast controlon film cameras. Contrast will be to a large extent a product of the light conditions e.g. low angular light will give you high contrast (sunsets) while filtered light on an overcast day will produce less contrasty light conditions. of course the direction of your light source (or rather angle of it) in relation to the lens will also make a difference - against the sun high contrast with rimlighting effect of a silhoutte. Sun at your back - lower contrast and more even lighting. Sun from directly above or at 90 degree angle will result in contrasty images with large contrast between lit areas and those in the shadows. These principles, of course apply also to digital photography. Contrast of processed photos could also be enhanced by selective exposure, dodging and burning, choice of paper, choice of film and choice of developing chemicals (more subtle). For real high contrast B&W prints made from normal B&W negatives I have used lithographic film in a long and tedious process but thats a long story of which I forgot half of the recipe!
Take care Annemette Joggie

No not at all- thank you very much, Joggie:-) I want to learn, and it makes perfectly sense to me. I do change the ISO in my digital camera now being adviced to do so. I can´t change the aperture though with my current compact camera with programs, but I´m hoping to get a mirror reflex digital cam one day, so I can start experimenting with the aperture and shuttertime. For now I save the good advice I get and experiment in other ways with perspective, light, colours, contrast, motives etc. How do I make high contrast with a manual camera? Is that possible at all or is it while developing the film that it can be done? Maybe some film is better for this? Sorry for all these questions, Joggie, but you seem very experienced within this field and a very pleasant teacher:-) Best wishes Annemette

Hi Annemette - The f-stop is a guide number for the size of the aperture of the lens. The higher the F-stop number (e.g. f32 against f2) the smaller the aperture of the lens and the 'deeper" the Depth of Field (DoF). In practice one control the available light through a combination of the aperture size, the shutter speed and the sensor sensitivity (ISO). If there is enough light available one can vary the DoF from shallow to deep by changing the aperture (f-stop) from a big opening (low f-stop number like f2) to small opening (high f-stop number like f16). With digital cameras we have the added advantage to change the ISO from one shot to the next by a simple flick of a switch (in the old days we had to change films or expose and force-process a low ISO film at a higher ISO, increasing grain and affecting colour). This is a mouthfull Annemette and I hope I did not confuse you or even this might be old news? please feel free to answer! Joggie

Dear Joggie Thank you very much for your good advice. I must try this in PS. The reason why I didn´t do it was that I was afraid to remove the red colour, but it might still be there. I´ll try it:-) What is an F-stop? Take care Annemette

Surreal effect Annemette - very graphic shot. Seems you have used your flash and overeposed by about a fstop. I would try to darken the image and heighten the contrast a bit in PS to get more contrast between the red background and the iceycles. This will also give more saturated reds and vibrant colours. Great effect anyhow and worth experimenting with! Regards Joggie
