Subtle Light leak?

Yes
I'm trying to work out whats going on here, the middle of the foreground is about a half stop lighter than the rest of that area and seems to be lacking contrast and texture. The other side of this DDS is apparently knackered judging by the enormous light leak on the negative that came from it. Thoughts? Both sides done in, errant reflection?

Strange place for a light leak to affect.

Sorry Steven, I'm not getting what you mean by this, whats a DDS?

Double Dark Slide - a sheet film holder for large format cameras. One sheet of film goes in on each side, and is covered by a dark slide. Before exposure (when the shutter is closed) the DDS is inserted in the camera and the dark slide removed, after which the exposure is made and the slide reinserted before removing the holder from the camera.

Sorry Steven of course it is, I wasn't even thinking you were shooting large format.
Ive had light leaks on a couple of my large format negs but that was with a very old and flimsy dark slide that I was already suspicious of. Iit only showed up if the slide sat on the camera for a long time while I waited for the light to be right for the shot I was taken or a shorter time if the sun was shining directly on the slide, I've now binned that one. The problem was that the leak was almost imperceptible if the shot was taken on a dull day or the camera sat in full shade and the dark slide spent only a short time attached to the camera.
It would be worth running a test and loading a couple of sheets and just leaving the slide in direct light for a period of time.
 
h'mm I can't see anything wrong in the shot considering it was difficult lighting conditions......if I had to nit pick it would be the sky which might be caused by uneven dev.
 
I'd be pretty convinced it is the light entry from thé opposite side of thé DDS creeping into the "good" side.
Assuming the knackered side is beyond repaîr, seal it up light tight and simply use the better side.

I thought that as well Brian as it's quite hard to see on this post but if you look at the largest size on Steven's Flickr page it's more obvious.
 
Oh well Nick I give up as I wasn't there when Steven took the shot and don't know what it should look like :confused:...but when talking about 1/2 stop lighter in parts that's getting into the field of Ansel Adam's work and can be corrected in the darkroom or these days Photoshop.

It's not a question of what it should look like, you don't have to have been there to realise there's something wrong with actual negative and the shot it has produced. It is very noticeable in the large version, its not a difference in exposure it is definitely a light leak from somewhere at some point before development.

Yeah I'm sure I'd used this one but the damage may have been hidden by another random act of idiocy. I'll defrost the spare fomapan and test it properly. Not sure how repairable they are but if one side is too far gone I'm not sure it's worth the weight for one side.

Could be the hinge of the other side. I'll need to investigate or just junk it, I got a load fairly cheap due to an ill timed auction end time.

As nick says there is definitely something odd on the neg, the light of the shadows was even. I only know it's a half stop because I turned the brightness down in light room till the area around it was black and it was roughly a half stop before that bit also went black.

Well for me it's annoying cos I can't see the problem :eek: Anyway a suggestion would be to find a grey (or similar) wall and take a shot or even point the camera up to an even blue sky....that should show any problems.

Have you looked at the largest version on Flickr? It's very obvious at the larger size.

How do you see a larger version on flickr? Sorry to ask such a daft question, but I've just stared round Steven's image, and apart from making it full screen I can't see any control for a larger version! It should be obvious, I don't understand the new flickr interface!

AH just found the "up" arrows..is the problem when looking at the shadow area on the right side from\by the hut, it's darker than the left side?

It's harder too find than it used to be but if you type sizes in the address bar after the last last forward slash / it will take you to the page with all the different sizes like this https://www.flickr.com/photos/49248828@N06/16176949671/sizes

I'm not sure if there's an easier way to do it but that's what I do.
 
Just left click on the photo,should take you straight to the flickr photo.

That's a handy link and at 2480 it shows the best result while others give different results to give wrong conclusions.....erm well I still can't see anything wrong in the shot other than just nit picking :rolleyes:

Help me out of my misery :D

That's true but it doesn't take you to the sizes page, Flickr in their wisdom have chosen to make that option harder to find.

I'm sorry Brian this statement makes no sense, if you can't see it at the largest size then I can't help you.
 
I can see the area, but I'm not sure whether it's a light leak or patchy development.

Two previous views I saw showed patchy sky and in another( in the shadow area) showed one side darker than the other so giving me the wrong conclusion......in the 2048 size the sky was ok and the shadow was ok.
Maybe it would help if the problem was ringed in red in Photoshop for members who can't see it.
 
Fresh twist, other side might not be goosed bit nuked by random idiocy. Looks like when I removed the back to change orientation I put it on the wrong way but I've likely as not put the dds in the right way so there would have been precious little light sealing... Doesn't help with this one though the back only works one way in portrait.
 
Fixer..

that's my answer to everything just lately :)


seriously....fixer
