I have been a drum scanner operator for over 30 years. However, we still want to know what the resolution of film is in terms that we can relate to, such as mega pixels. I do tend to use the largest practical film sizes for quality reasons, but I don’t like to see the issue unnecessarily confused “. One would therefore imagine that the former has 4 times the resolution of the latter. ShinyPhotoScotland 11 years ago. You can always find support for whichever “camp” you want to be a part of.

All 5 Mp cameras are not created equal. In one of those tests, it took a Nikon De to match 35mm slide film, and an IQ to match 6×7. But grain is not linear and a print is 2-dimensional. Hi Oly, Thanks for the reply and info, really thanks. I scan my 6×6 at ppi on a dedicated film scanner and make 30 x 30 inch prints, un-interpolated, and they look great. Raw NEF captures, of course. I don’t remove 35mm slides from their mounts, although with the Pakon mounts it’s easy to remove and replace the slides. I still don’t have a digital camera that can compete with 4×5-inch film, though.

Because only one in four pixels are blue or red, quite often colour resolution is reduced in comparison with luminosity resolution. Therefore, there will be less degradation of image quality due to the enlargement of film grain structure, and other artifacts. Or a MF digital back, which will take you past what you’ve got. That results in about a dpi “scan. Nikon Nikkor Z 50mm F1. I also used to do a lot of slide duping, using Ektachrome slide duping film and Fuji CDU as I needed to send out slides to several stock agencies.

Not enough to change the narrative though – and it requires a digital camera to achieve, anyway!

Waht is the film size/MP equivalent? | Photography Forums

That is refreshingly different. How many of us own a monochrome digital back to level things, right? Of course, there’s always fine tuning to do of every scan.

For MF and LF it means sequentially positioning each of the four corners of the film in the viewfinder, squaring up the edges of the film with the edges of the viewfinder and taking one shot at each position for the four images to be stitched in Photoshop. The range of resolution needed obviously depends on image size and viewing distance.


Digital pixelation is in the form of little squares and that will cause the human brain to send up a flag as little perfectly straight sided squares almost never occur naturally, if mgapixels occur at all.

This tripod has an unusual center column that can pivot to swing as low as the tripod feet. Resolution with the De scans is better than I get with the drum scanner, and acutance is actually higher. I use a an old folder shooting roll with a 4cm x 6. The former will have better resolution and detail than the latter, but that won’t make it more interesting in and of itself.

36 Megapixels vs 6×7 Velvia

My tests have also shown that going above ppi doesn’t add useful image detail, megapxels is why I don’t use the D for 35mm. My Imacon-scanned 6×6 come out at around MB I think.

I’m not sure why he’s so keen on the diagonal. So far without success. Ben Syverson 11 years ago.

What was the film scanned? The progenitors of GFX: MF with a 6×6 format and a usable 55mm x 55mm negative will then result in 3. It was late in the day and I got my wires crossed. Where can i get mm film from? While film itself might have a high resolution and an ability to capture endless detail, what we end up seeing is limited to the quality of the output method.

This explanation took much longer to type and probably to read than to actually carry out. A closer look at Fujifilm’s medium format concepts Feb 18, What if you are a mole?

I think it’s not the film scanning result It’s a subjective choice; don’t try to make it objective by dragging numbers into it.

This translates into one-thirds of the resolution for each color, which means that the megapixels states by camera manufacturers for their products are grossly exaggerated.

Once you “scan” a picture taken with a camera megapixls film it is no longer an analog picture, but a digital representation of an analog picture. However – one thing it does prove is that medium format lenses are quite capable and have a lot of leeway left for sensors to increase in resolution substantially. By default it will increase contrast to what it anticipates humans like to see, but when the subject is an already contrasty slide, that’s too much.


Mwgapixels it is better. On Amazon just search for “Artist Light Table. In many cases except the 1Ds and 14N family the digital sensor and film used in the same camera don’t have the same size, with digital being megapixfls, i.

It was posted as a three part series:.

Mawz Posted 11 years ago. I was “sure” the setup couldn’t possibly equal the optical quality of the laboratory-level “optical bench” and photomultiplier technology of the scanner. Digital files are smoother, sharper, MUCH more flexible, much less noise. Where can I develop a mm film? Last time I checked there was no CCD 6z7 to the paper backing. If you don’t have a darkroom you can feel them in a changing bag. Personally, I don’t waste my time printing from CCD scanners, I send everything film I have printed off to be drum scanned and professionally printed.

We’ll assume you’re ok with this, but you can opt-out if you wish. Please correct me if I am wrong For 35mm, I think a resolution of 85 squared pixels per square mm of film is enough which is 6 megapixels.

Waht is the film size/MP equivalent?

Alamy use this IIRC. First of all here’s the test area again slightly different than above. Michael Reichmann’s concusion was that the Canon 1Ds outperformed 67 Velvia. Note that Phase One actually sells a similar setup based on their digital backs for museum archival of large format negatives and prints. That should get the trolls out in force!
