Point made.

But there could be very high pixel count sensors aimed at people now using MF cameras. In fact I would expect 42MB by the second generation. Not much use for the average photographer..and the storage!
 
?????
Does this thread require a secret decoder ring?
What 35 MP dSLR with alpha mount? What point has been made?
What is it these three photographs are supposed to illustrate?

Nothing special. A rumoured A1000 utilising a higher pixel count to 35MP is on horizon while I am scanning my films to a resolution of 35MP. All these photos were taken with Minolta film cameras and scanned using Minolta Dimage 5400.

At this moment in time the images in the original post are not available anymore so I cannot judge the scan quality. Either way there is one important rule in scanning negatives and slides; it is pointless to use a resolution so high that it resolves film grain.

Grain does not provide additional sharpness so the scanning resolution should be picked at a level that film grain is -just- not resolved. This means that the optimal scanning resolution for an ISO 400 film might be considerably lower than that for an ISO 50 slide, assuming both are correctly exposed.

As the links in the initial post are dead I also cannot see what point the OP is trying to make.

Regards,

Hans

what's wrong with scanning grain? get as much information into your comp as possible, and then manipulate it later.

given that you can't always just scan to a level that just excludes grain, just scan everything and deal with things on your comp.

although i accept that large files are not always pleasant to deal with...
 
So I see.

I plan on scanning all my old 35mm B&W negatives using an electron microscope. This will yield resolution down to the texture of each grain of silver-halide :)

Hello Gilbod

I guess that all scanners have an adjustable range of resolutions so it should be possible to find the optimal value for a given roll of film before scanning the whole thing. The point I am trying to make is not whether or not the files are too large but the fact that scanned grain does not add quality or extra detail to the image. Actually it is the opposite, if a grainy scanned image is resized to a smaller size the calculation will include the grain which will result in a poorer image quality than when the process is started with a resolution that excludes the grain. There is no way to remove grain from the files and no, high ISO noise is something completely different.

Happy shooting! (or scanning of course)

Sorry for the broken link
Here are some others,







I have not worried much about the grain, and never bothered to use the build in function of grain dessolver and grain reduction.

However, viewing from reduced size, the colours of the scanned images are spectacular and just wonder if the newer CMOS at higher pixel count can do the same job.

I wish the link will work.

I have been using VueScan to keep DNG file but do not understand the enormous size of the file. I believe even the file size of current 45MP camera is less than 100Mb

You must always scan at the highest possible resolution.

At lower resolution, there is more grain because som grain particles are clustering together.
