At 10 stops, it looks like an old late 1800s image with that faded flat look. :-D

[@graydeotto2820]

Im shocked that I actually prefer 2-3 stops over. I've always shot my hp5 at box speed and now I'm not sure if I should be

[@SugaHoneyIceTea36]

From what I’ve seen measured at 800 and pushed 1 stop is nicest but agree overexposing and developing at box speed is nice. I even prefer -1 over box 😅

[@messsucher]

Overexposing 7 stops on this film is just insane to think about, especially with that descent result! HP5 is always known to give great results when pushing the film, so a lot of people who loves grains in their photos would shoot this film at ISO1600, then pushed in post, and it should still hold good details in the dark. So even if you don't have a lot of light, pushing the film should extend some limits, if you are ok with grains tho, lol.

[@scottparis6355]

Well OK, except notice that even at one stop under, his shadows are noticeably worse. Pushing is fine when you're forced to do it by darkness, but it never results in good tones.

[@messsucher]

@@scottparis6355 Well yeah, it will happen to all films because its not the designed box speed. but there are just people who like it that way, its a preference thing, not good or bad tho. From a perfection stand point, it might not be ideal, but artistically it should offer good results

In the past month I ran literal search term "kyle mcdougall ilford" 3 times. Thanks!

[@KyleMcDougall]

😁

[@kiodo99]

This is actually really useful for times that you want to use an older camera that doesn't have a very fast maximum shutter speed (e.g. 1/400 or 1/250). This sets my mind at ease that I could use those cameras without worry, and could even open the aperture a bit if I wanted. Thanks for the great content, as usual!

[@KyleMcDougall]

No problem. Glad you found it helpful!

[@dovydasgrigas441]

my exa 1b goes up to a whopping 1/175 so these videos are a godsend

[@kurtozan251]

Waiting on my scans but I just shot this exact stock with an old wideluxe and had to overexpose a lot. I'm sure the scans will look good.

[@yeanisch]

Exactly this. I've got a zenit E with a broken lightmeter and a helios with a stuck aperture (F2), so this is very good information to have. Now I can look at my canon, and if it's lightmeter gives me a good exposure at 2000 shutter, I know I'm safe with 500 on my zenit.

[@lensman5762]

Your explanation was useful for those who have not shot film before so well done. If I may make a couple of points here for information. Any film Developer combination has a unique Log D-max curve hence an exposure index, this curve simply indicates how density builds with exposure, this is almost always an S shape. It starts with a ' Toe, muddy shadows without real detail ', leads to a' straight line, good exposure values ' and ends with a ' Shoulder, blocked highlights '. All three sections are of interest to a BW photographer. HP5+ in combination with a highly diluted HC110 or ID11 ( D76 ) at stock or 1+1 has a short Toe and a very long Straight section before eventually ending with the Shoulder. What this means is that subject to a scene's luminance range ( inaccurately known as Dynamic Range ), the film can be exposed at the averaged of high and low luminance values and, more often than not the results are usable. The problem starts when the luminance range of the scene is vast, as in a sunlit scene or a scene with objects of very high or low reflectivity. In such cases without the use of a spot meter and knowing the exact exposure required to obtain shadows and highlights with detail the negs can be wrongly exposed and important delicate values lost. In your presentation , judging by the shadows, the sky seems to be overcast and the luminance values of the scene within 4 or 5 stops. Under these conditions provided that the exposure is not placed in the ' Toe ' section ( severe underexposure ) the film can be exposed at a range of exposures within the ' Straight Line ' of the curve and values retained to a great degree as demonstrated.

[@KyleMcDougall]

Thanks for the explanation.

[@PhilTaylorPhotog]

Hi lensman, some time since you wrote this, but I'd like to ask why you mention the term dynamic range is incorrect? Is it purely because dynamic range is measured in Db and therefore is only a digital measure? If so,I completely agree, and would say film has "latitude" , digital has "dynamic range" and a scene has "luminance range". Just wondered if you had another reason?

[@user-ti9zc1xv2b]

@@PhilTaylorPhotog Because dynamic range does not apply to film only to digital.

[@captasin7991]

Should try Tri-X also for B&W comparison

[@KyleMcDougall]

On the list!

[@timma_thy]

This video makes me want to shoot some self portraits on tri x.

[@ebouwman034]

I feel like you HAVE to compare tri-x when doing hp5.

[@Apprendre-Photo]

I'd also be curious if HP5 pushed has the same latitude ? Because if it does, then you could basically rate it at 1600 and consider your film to be on "auto ISO" all the time :P

[@uglybassist]

HP5 has been my general purpose black and white film for about 2 and a half years now. I push it to 1600 which gives me a look similar to Tri-X at box speed. This gives me a pretty huge range of camera settings in anything from bright sun to artificial light indoors with my FM2.

[@andymcdonald372]

Excellent video, very useful. I have just started back into black and white film and knowing how HP5 reacts over and under is going to really help me

Impressive results! A friend of mine shot a roll of 120 hp5+ at 6400, I developed the roll where I spent 30 minutes agitatating and the results was excellent, the scans showed a impressive amount of details especially in the shadows! Keep up the good work!

[@paulschumacker9901]

So you use your ISO based on the lighting you get during the day, and then just develop at 400?

[@mattdavis9986]

@@royaltykidstv yeah, it’s a bright day I’ll set the iso to 100. If it’s a dull day next time I pick the camera up with the same roll inside, I’ll set at 800 or anywhere in between and develop at 400.

[@royaltykidstv]

@@mattdavis9986 Wow that’s crazy. Everyone who I have asked about film are super strict about sticking to one ISO throughout the film. And they have told me to choose wisely. I guess your method should work better. It’s like you cracked the code. Thank you.

If you are new to film, stick to box iso until you learn proper exposure. Once you have a few rolls under your belt go balls to the wall and throw the rules in the trash.

[@dougelick8397]

This is an excellent overview. If you ever have the time, I'd love to see a repeat under a much wider range such as full sun with shadows as well as the histogram for each image. Such a test would give a better indication of how the film blocks up under varying conditions. This same test with Fomapan 100, 200 and 400 would be invaluable. None of the Foma films seem to live up to box speed, but are decent and cheap. I've heard multiple people say Fomapan 200 shot a stop over is great.

Just for jollies, I took a shot on my digital camera overexposed 5 stops. Got a white screen. Heck, in studio I get a pure white background way below that. Another great video Kyle. Great content and great sound, so many youtubers sound like they are in a tunnel and are unwatchable. I use HP5 for street, expose for shadows and never miss an exposure. With zone focusing, it turns my slr into the speed of a point and shoot. I also like the amount of grain and the low contrast that is easily tweaked in post either way. Thanks for a great video and I don't think anyone else has done this and this is for people who actually shoot, not just test patterns and shoot in realville.

[@KyleMcDougall]

Cheers, Bob. Thanks for the comment. Glad you enjoyed this one!

[@VintageTechFan]

Now underexpose 5 stops (use RAW though) and be amazed what you can recover from it. It should be really close to cranking up the ISO setting 5 stops at the same time/aperture.

[@SivertAlmvik]

Back in the day, when I shot film daily, I always shot with one stop overexposure. Every type of film stock. I felt it was safer and it always gave me better latitude when I printed or scanned digitally. But 7 stops! Holy shit, HP5 is a beast!

[@warwickwallace2699]

You are our sacrificial lamb so to speak haha. You do these so we dont have to and for that i thank you endlessly

[@luca_hc_gruber]

It would be really nice to see the negatives once they get back to you. I wsnt to see just how dense the overexposed frames look and what the scanner could recover from them.

[@RickScheibner]

Same, and I was getting ready to post that suggestion.

[@KyleMcDougall]

Will do in an upcoming video.

[@BryanBirks]

Just please do a video on every film imaginable. I shot HP5 pulled to 100 because of risk of overexposure. Nice to know I have that extra cushion if I don't want to pull in processing. Crazy to think the image at 5 over looks roughly the same if you added in some contrast to it to match the regular exposure.

[@KyleMcDougall]

I’m feeling now like it’s one of my missions, haha!

[@andyvan5692]

wow, great tips and video, GREAT beginner film, esp. for 4x5" sheet, if this responds simmilarly, but great to hear how it works, BEST over exposed, NOT under, so a good safe film to start on, just err on the OVER side, little lost in quality, but not much.

[@KyleMcDougall]

Definitely a great choice to start out on!

[@rmrfboy]

7 stops and still looks crazy good! it would have been nice if you zoom in to see what the grain is like on rating the ISO to 50 or 25. my take on hp5: its freaking versatile, i should say!

[@bthemedia]

Nice to see, but please consider adding the stops / EV compensation values on the screen too 👍

[@mariomissagia4976]

thanks a lot. Nice and util video!

[@MrNev27]

This gives you a useful guide as to the dynamic range of the film, at that development, which appears to be about 10 stops. Pushing or pulling the ISO with altering the development time will increase or decrease the dynamic range, which is the principal behind the zone system developed by Ansel Adams.

[@PhilKnall]

Totally expected the overexposed latitude, actually expected a little better with the under. Agree with others that +1/+2 looked really pleasing!

[@FreeManFreeThought]

I've got my Mom's dad's parents old Brownie. Definitly need to get some 120 and give it a try. On another note: just develop B&W at home :) it's fun, and quick too. 20 minutes to develop (or less) plus about 40 to dry. The chemistry is only about $30 to start, and will last you a while.

[@sbutler66]

Welcome to the UK!

[@KyleMcDougall]

Thanks, Stephen.

[@JamieMPhoto]

I expected it to hold up pretty well, but that's still super impressive. I bet this helps with street/documentary because you can err for overexposure and you can risk missing exposure to capture a moment.

[@KyleMcDougall]

For sure. Was really impressed with the results!

[@neppybynature]

I see a Kyle video, I watch the Kyle video

[@philhindmoor7569]

Thanks for sharing, I think where the light allows I will probably try rating the film at 200, as I look the +1 picture.

[@KyleMcDougall]

That’s what I would do.

[@cameronwheatley7065]

Fascinating test! I think it's always important to stress that 'overexposure' is a relative term though - in this case 'overexposure' is defined by your skin reading. I prefer the '+1' shot because your dark shirt has a lot more detail in it, whereas it seems a bit dark in the 'normal' exposure where your skin = middle grey. I guess it's a great example of why understanding the zone system is important as you'd usually place caucasian skin in zone 6 (i.e. the +1 exposure in this test).

[@scottparis6355]

Exactly. White skin isn't 18% gray.

[@KyleMcDougall]

Hey Cameron, I should have been more clear explaining how I metered. It sounds like I spot metered my skin, which would place it at middle grey. But I actually used an incident meter right in front of my face, which would place skin in the proper zone. Should have worded that differently.

[@cameronwheatley7065]

@@KyleMcDougall ah right good to know. I'm still yet to fully understand the theory behind incident metering.

[@dunerino892]

when it comes to b&w film the developer makes quite a difference for the negatives in terms of grain, sharpness, contrast, shadow details... since there are sooo many out there and for color negative there's just c41...

[@JRichardctr]

As always, great video content. Everyone loves seeing these comparisons posted. Does your camera not have enough shutter speeds for this test? A consistent aperture seems like it would really affect the overall look of the image and should change as little as possible for this kind of test.

[@KyleMcDougall]

Yep, it does. Thats what I’ve used in the past. But with the 16 exposures, it was a balance between the two to avoid shooting with too slow of a shutter speed.

[@nateeames6826]

This is a really great series! I’d love to see you test some slide film. Maybe Provia 100 would be a good place to start since I’ve heard it has the best latitude of any slide film. Might be better going by half stops though since there’s no way it’ll be getting to something like -10 (let alone +10).

[@KyleMcDougall]

Provia is on the list!

[@MichaelDFarrellJr]

What are you using to develop? The type of chemistry, its dilution, and how much it has been used can really impact your results. If outsourced developing there can be a lot of variables preventing consistency. If developing in house, you may want to take a densitometer to some frames of 18% grey, black, white, or otherwise, cards at various exposures using the developers you want to use with the film. Nailing down all the variables can be hard, especially with a hybrid process where each step has the potential to cary your results.

[@-dubu]

I've shot hp5 at 12800 many times and had completely usable results, they look more like your 1600 shots. The way you prepare and develop your film makes a huge difference.

[@Biosynchro]

That is a very good point indeed. Different developers with different techniques make a big, big difference.

[@tiansili]

Which developer? Temp or time push?

[@DartzIRL]

Once inadvertantly knocked my spotmatic from 1/1000 to Bulb. With Fuji superia 1600.; It must've been near 10 stops over exposed. The film came out near solid and non-transparent. But an image was still gotten from it.

[@AlexLuyckxPhoto]

Love HP5+, I find that the sweet spot for the film is between 200 and 800. My personal favourite is HP5+ at 200 and developed in Pyrocat-HD, amazing tone, contrast, and sharpness.

[@Larpy1933]

Alex: Oh Canada!

[@lioncityhyperbole]

Thanks for showing this, super helpful! Could I seek your advice - if I increase iso during shoot and reduce exposure compensation correspondingly during shoot, do I still have to push it during development?

[@Raevenswood]

I like shooting HP5+ at 200 ISO and then pulling 1 stop in development. It also shoots well up to 1600 ISO with push development. You can definitely just shoot it overexposed without pulling like you can with color neg but it really gives good highlight detail while also giving lots of shadow detail if you pull in development. With Black and White there is so much flexibility in development because the development process is not standardized like C41 so you can get all kinds of different looks from using different developers, dilutions, and times. FYI I recommend you try Ilford Delta 100 and 400 next (if you haven't already by now)

[@edshotsdotcodotuk]

Highly rate HP5 as a film. Forgiving and looks great out of the box. IMHO it's the best high speed b&w film when shot at 1600 ISO. Way more detailed than the Delta 3200 with it's larger grain. The warmth you saw could be due to the lab more than likely using a Fuji SP3000 scanner and from what I've seen at the lab where I work it has a magenta tinge when scanning b&w. We also have an Agfa DLab than doesn't have any cast to it (I personally prefer than machine but it sadly can't do higher than 3000x2000 at 400dpi).

[@tysaylorphoto]

I always over expose by 1-stop on HP5. Maintains contrast while extracting detail in the shadows.

[@Twisted_Sound]

I think HP5 is the most versatile B&W film out there!

[@VariTimo]

Please do the CineStill 800T test with and without an 85 filter in daylight. Ideally you’d also make another row of test in a tungsten light night scene but daylight with and without the filter will give most people a very good picture of the film. I’ve been shooting it for over two years now (with an 85 filter in daylight, as you’re supposed to) and am absolutely loving the colors and contrast. The grain is a bit much on 35mm but I’m not blowing them up a lot, so it’s fine. Btw exposing it at Kodak’s original 500 ASA will give you the best results (that is 320 with an 85 filter in daylight on a non a TTL meter). Also I looove that you’re in the images know. I’ve always missed skin tones in these tests.

[@KyleMcDougall]

Cheers. More tests to come. And I will be doing 800T.

[@brianorakpohit]

Interesting. Depends on the subject though. I shoot HP5 120 a fair bit and if I was shooting a landscape of some kind, let's say sky, boat, beach, I would not want to go half as overexposed as you did here for the self portrait. Film portraiture, as you know, loves overexposure, but it depends on the scene. A blown out sky very rarely adds something.

[@KyleMcDougall]

[@708photog]

It's great seeing these types of tests and results with color neg (and positive) film. But when underexposing B&W film you should push (extend) the development time. When overexposing B&W film you should pull (shorten) the development time. I realize that the roll was lab-developed (I assume the lab used the "normal"/published development time), but seems like this note is at least worth a mention.

[@jonathanmerritt6195]

This is true, but it’s more important for seeing proper results with underexposure. The old mantra of “expose for the shadows, develop for the highlights” is a great technique, as evidenced by how well the overexposure tests look in the video

[@michaelgroenewald1114]

I love this film because i can run it on my mamiya 645 80mm at 1.9f wide open at max 1/500 without filter (have the older one, not a 1000s)

The last roll of HP5 I shot on my 1970 Miranda Sensomat RE 35mm was bad. Most of the roll was underexposed by about three stops. My light meter reads too low, so I've been pulling my film by rating it at least one stop below box speed with the needle slightly high. It seems to have done the trick. That HP5 roll was mud city.

Thank you

Hi Kyle great test. I have some HP5+ and look forward to using it. I have a quick question do you know what developer, developing time, and temperature the lab used?

[@KyleMcDougall]

I don’t unfortunately. Never thought to ask, although I’m realizing I should have!

[@JakeFosmire]

Impressive! I thought it would be toast at 6 over

[@RichardStroffolino]

So cool to see, thank you for doing this with black and white. HP5 is really the duct tape of black and white. Out of curiosity, do you know what your lab developed in (I'd assume XTOL but you never know)? I'm metering all my HP5 at ISO 3 from now on!

[@KyleMcDougall]

Glad you enjoyed. Unfortunately I’m not sure what they developed with. And ISO 3... 😁

Would be super helpful to have one of these for HP5 and/or Tri-X pushed to 1600, where i think most people shoot it anyway

[@KyleMcDougall]

Definitely plan. to do that in the near future.
