Are these grains or over sharpening?

A crop from a lab developed and scanned image

Film: Neopan 400 pushed to 800
 

how does the whole image look like?
 

looks like oversharpening
 

Wow that's pretty terrible.
 

is it only a few shots like that or the whole roll?
 

was these developed and scanned in Burlington Square?
 

It looks like oversharpening. Was the developed negative very thin?
 

Looks like the pictures are seriously under-exposed. When the scanner tries to pick up details from the negatives, it resulted in such high grainy images. I suspect your negatives looks whitish and blury.

I suggest you stop trying "pushing" and shoot as rated on the negatives. Develop the negatives yourself will also yield much better results from the labs.

This is just my suspicion. Hope that helps.
 

I kena this a couple of yrs back with a roll of ilford deta 400 pushed to 800 while trying with a new camera and wat Chiff mentioned here is right! I got to found out later that there was a problem with my shutter speed hence the underexposed images!

Yup, Triple D.

Most are exposed quite normally. The brighter ones seems to have a little less artifacts, such as the one below.

Time to save up and invest on self development and scanning :(
 

The scans that you have demands a rescan or refund imo. Get your own scanner, it makes can do much better scans since ur shots are exposed normally.
 

Use a magnifying glass check on your neg. (10 - 30x). Most likely is not the grain pattern but other software generated pattern and some over sharpen.

Agree with Chiif. It looks like the roll is underexposed, and the lab scanner is trying to compensate by upping the exposure during scanning. This results in a grainier image with loss of tonal detail. On top of that, the sharpening looks a little aggressive, resulting in the artifacts you are seeing.

Even in the the "better" examples you posted below, you can see the images area very contrasty and there isn't much shadow or highlight detail. So my guess is that on top of the one stop underexposure you did to get Neopan to 800, you may have underexposed by a further one or two stops. Are you negatives very thin (i.e. the image is very faint)? If yes, then there is definitely underexposure.

Could your camera meter be off, batteries need to be changed, etc? I think before you jump the gun and invest in a scanner or do self development, maybe you should just shoot another test roll and send for processing to rule out a metering issue with your camera.

For this roll, you shoot in a controlled lighting environment (e.g. indoors) and maybe include a piece of paper in the shot with your exposure settings written on it so you can keep track of which is which.

What you do is to shoot the film at box speed, e.g. ISO 400 without pushing, and then bracket your shots, e.g. "correct" exposure as suggested by camera, then +1, +2, +3, -1, -2, -3 of the same scene. When the negs and scans come back, see if they are all showing the same artifacts at all exposures. If they are, then it's the lab/film's fault, and you can consider changing film or lab, or both, or even self development. If only the underexposed shots have this issue, then it is the underexposure causing the problem.

If it's underexposed for the whole roll, maybe the lab didn't compensate for your "pushing" when they develop your negative. Just a thot.....:dunno:
 

Sharpening, without a doubt.. grain doesn't look like this...and if my theory(from my understanding how sharpening works) isn't wrong.. the sharpening algorithm actually ends up connecting the grains together like connecting the dots resulting in a mosaic like pattern..
 

To TS, aren't you surprised that i guess correctly that u scan at DDD?;) Even a cheapo Canon 8800 scanner can scan better than DDD.
I have encounter these problem w them before. You try re-scan all the neg, mayb from someone scanner etc, I very confident there's nothing wrong w your neg.

Agreed, at this ISO, you shouldn't be seeing the grain esp if image size has been reduce, and viewing on computer screen.

Whether you scan at a lab or scan with a flatbed, all I can say is got no such thing as cheap and good.. even imho a V700 is cmi.. but if want cheap.. den one has to adjust expectation; its a fact of life and there is nth wrong with that. What is wrong though is when you overpay for a service and get equally rubbish result;)
