This is why almost everything I shoot is shot at box speed and developed normally.agreed but if you are using roll film with subjects of different SBRs then you need a strategy/methodolgy that works for all shots on the roll.
I suggested in earlier topic that if he's in studio and whole roll of film is used in studio, to revert to using box speed. If he's out doing landscapes I'd use calibration for 10 stops range but thats just me.This is why almost everything I shoot is shot at box speed and developed normally.
If I was in Jessestr's position though, where 90% of my work needed grade 5 paper, I'd adjust my normal film development parameters to where I was able to use grade 2 or 3 as my norm.

Some people just use manufacturers recommended dev, temp time, expose for shadows and deal with contrast when printing. But as I have repeatedly stated, thats fine if SBR is 6 or 7 or more stops but its not fine if SBR is only 3 or 4 or 5 stops becasue you really won't have as much highlight negative density as you need which causes printing difficulties.
Always thought of increasing dev. time as a last resort... but seems like the most normal thing on earth having read numerous of comments now..Yep.
Per Ilford:
" Note Development times may need adjusting to suit individual processing systems and working practices. If an established system is producing good results, adjust the recommended development times until the desired contrast level is obtained. Development times in other manufacturers’ developers are included for your convenience, and are only a general guide. Other manufacturers can and do change their product specifications from time to time, and the development times may change as a result. "

I explained this in earlier topic.And what exactly does make printing easier if the highlight density is okay? I'd like to know the reason/logical connection behind this.
Develop the paper until the paper has gotten to the desired state. The development time is not important; the resulting print is.
I explained this in earlier topic.

what have you been exposing for, shadows, highlights or midtones on your earlier negatives. And assuming you were using ISO speed and manufacturers recomended development, how much were you adjusting metered zone to place it where you thought it should go? i.e. if you were metering a zone 3 how much were you closing down? Or if you were metering a highlight, how much were you opening up? And what was the SBR of these subjects? Or were you using an incident meter? Did you make notes so you know what you did with each shot? always a good idea to make notes when you are learning so you can work out what went wrong.
The problem you describe here is the problem an incident meter solves. It eliminates the guessing about which tone is which zone.I always metered a part of the skin and put in in zone 6 (opening one stop), or at least the part of the skin that I wanted to be in zone 6. Is that a bad workflow? I did not take notes, so I don't know the SBR.
I found it very difficult to get consistent negatives with the spotmeter because the skin is so variabele, some have darker or lighter skin, the shadows casts by the light make the skin look like zone 5 or even zone 4... And it was hard to actually think how it would turn out. Maybe there's a better way to meter a portrait... I don't know.. never read anything about it.
I meter a zone 7 or 8 and expose for it in the knowledge that I will have a decent negative density for it. Zone 7 is full textural detail ust before it starts to become blown out.
For a model I might meter for a zone 6, 7 or 8 depending on skin colour and highlighting on the face. So the brightest part of forehead maybe zone 7. But if face is under the shadow of a hat then I might just put face on zone 6 or even zone 5 depending on how much shadow or exactly where I wanted the face to be.
Zone 7 or 8 is a good choice you have it in your subject because it will put that zone a sufficiently high negative density. But only if you have calibrated your dev and/or know where it will be.
If you are using box ISO speed and manufacturer recommended dev, then you will get a useable 7 stops of range so treat each zone as 0.7 of a stop instead of 1 stop. So to place something on zone 7 then you meter a zone 7 and open up 1.4 stops or 1 1/2 stops ( a tad of extra exposure won't hurt.
If you have calibrated dev as I suggested for for 10 stop range then meter zone 7 and open up 2 stops.
The next person will tell you to always meter and expose for a shadow and a lot of people do this and have no problems. But if using box speed and manufacturers recommended times, you can't meter a zone 3 and close down two 2 stops becasue you'll be too far in the shadows. You would need to close down only 1 1/2 stops at box speed and manufacturers recommended dev, temp and times.
So it all depends on what you've calibrated for and your SBR. But exposing for a highlight will always put your neg highlight density close to where you want it regardless of SBR. And that makes printing easier.
The problem you describe here is the problem an incident meter solves. It eliminates the guessing about which tone is which zone.
On those "thin" negatives is the shadow detail you want to print well defined?I've been experiecing more thin negatives with my incident meter. Could be my fault though.
Rob, just few more questions to be totally clear about the exposing/developing part.
1st question
If the SBR is 5, darkest on grade 3 and lightest on grade 7. I still need to meter on the highlights right? So only meter on shadows at SBR > 10 (black to white)
2nd question
If my SBR < 10 and I expose for the highlights, can I still use the increase development trick?
As far as I know right now, that isn't necessary anymore right? It's either expose for shadows and adjust dev time OR print at higher grades OR expose for the highlights and print at a slightly higher grade?
3rd question
About the 10 SBR calibration, you mean this right? (there was a url link here which no longer exists)
I think if I get these answered I'm pretty much satisfied with what I got to know. Really interesting to talk about and learn to understand the whole process. Not easy though.

1. yes
2. no
3. yes
BUT as I said in previous post, if you are doing studio work then stick with ISO speed and manufacturers dev and use incident meter.
If you are out doing landscapes, then calibrate to 10 stop range and the answers to 1,2 and 3 are as given.
And if you really want to use 10 stop calibration in studio then you can if you are using a spot meter (but it would be better to use incident meter in studio without 10 stop calibration).
I'm going to suggest an experiment for you.
Using test strips, make a print of a section of your image that contains the highlight areas that you are most interested in. If possible, include some important mid-tones as well.
Adjust the exposure and contrast to make the test strip area look exactly the way you want it to. Don't do any burning or dodging on the test strip. Make sure that the test strip is fully developed.
Now print the whole image using the exact settings you used for the acceptable test strip.
If you can, post a scan of the whole print, along with your impressions about the areas of the print that are outside the test strip area. Include the details about what contrast setting you used, as well as the print times.
Another one neg that was very thin (I'll show this one when it's dry). I did a few test exposures, had to get to grade 5, and increased the exposure time to get "ok" blacks.
Please post the test strip as well.Will post when it's dry...
Funny thing is that I wanted the shadows to fade away. But yes, the print turned out much better then the scan I had from it.Regardless of the work and compromises you had to make, did you get the detail you wanted in the shadows?
I willPlease post the test strip as well.

But could have been very short SBR.If the shadow detail you wanted was available to print, the film wasn't really underexposed was it?
Given the use of grade 5 paper and the acceptable shadow detail available, I'd say that development was the reason for the thin negative not the incident meter.
That's what I'm implying.But could have been very short SBR.
