A couple of questions.......

[Paul Jenkin]

Hi again, I'm a relative newbie round here and need a bit of advice:

Firstly, I don't develop or print these days (insufficent space). However, when I have my negs developed, what would be a good specification to ask for when getting them scenned? I presume TIFF is a 'must' and that 300 dpi is what we should normally print from - but what resolution is acceptable. I just had my first roll done by a high street processor (I know, I know....) and what came back was okay negs but 36 JPEG files of 400kb......

Secondly, with an M6, do I need to alter the exposure to compensate for when I have filters on the lens?

Sorry if these topics have been raised before but your advice would be a great help.

Thanks,

Paul 😕

Dont know about the scanning but you dont have to compensate for the filters if you are using the built-in exposure meter, it measures through the lens (and hence the filter too)

What EmilGil said regarding the metering. As for scanning, it all depends 😉

IIRC when I get a C41 neg film processed, they gave a CD with approx 2.x Meg Pixel scans, something like 1800 x 1200. The short side of a 35mm neg can roughly be seen as an inch (ok, ok, it's a tad shorter), so this translates to about 1200 dpi (dots per inch). More is better, until you touch the resolution limit of the film.

A jpeg of 2-3 MPix size well as about 200 Kbytes, depending on the compression factor. Open an image in a viewer and check the pixel dimensions.

I use my own film scanner and normally use either 2600 dpi or 4000 dpi as a scanning resolution. 1000 dpi is still OK for 5x7 inch prints and probably even larger ones.

I'll only add that with "extreme" filters such as deep red, you'll need to open up a stop or more than what the meter indicates.

For an 8 x 10 print at 300 dpi, you need a file 3000 x 2400 pixels.
