Adox Colour Implosion
is a colour negative film, which produces images ressembling strongly those of the 1970s.
It does not have an orange mask, but rather a magenta mask, which changes in intesity according to exposure/development (pushing reduces intensity of the mask, pulling increases it). This slightly affects the tint of the imagery.
OPPOSITE to what is stated on the web, this film produces very much reproducable, and NOT AT ALL RANDOM COLOURS, given that you let it be scanned as colour slides (NOT as colour negatives) and that you take care of colour correction / mask removal yourself (see other topic: photography-f36/how-to-remove-an-orange-magenta-mask--t3175.html
). Any random element only results from the autocorrection methods of modern printing machines not being capable to handles this film, esp as these tend to digitize imagery before printing (unfortunately).
The film has relatively large grain, but IF you expose it correctly, this will not be as apparent as on most of the images available on the web. However, the film gives little headroom, meaning underexposing it a stop or so makes it already extremely grainy.
I tend to expose the film at ISO 64 and let it have being developped pulling it by -2/3 stops. I have done films at ISO 200 and 320; I didn't find the results would change significantly, but I will need to look into this a bit closer.
