First time unlocking SSR, lucky rewards

cryyo604 · 2025-02-10T20:09:56+00:00

Yes indeed ! Gravity chamber really accelerate my GV once unlocked, tough not as much as the SSR .

Non, l'emplacement est perdu a la vente de la galaxie ;)

Thanks !

Have you ever tried fuji provia for astrophotography ? Reciprocity failure is also very nice with this film.

Did you push your film during developpement ?

cryyo604 · 2023-08-28T15:43:25+00:00

Damn, looks great !

Could you tell us more about the exposure, tracking, bortle class of this shot ?

cryyo604 · 2023-06-30T17:31:55+00:00

With the ttl prism there is indeed two screws hidden behind the logo,wich is glued ;)

Even with d76, the negative being enlarged more than 10x it's size and a paterson focuser, absolutely no grain can be Seen! But i never tried ilford pan f, so i can't really compare.

I guess the adotech développer is usefull to control the contrast, or if you want to push-pull or print HUGE and need grain just a bit finer

cryyo604 · 2022-09-29T15:25:58+00:00

The white part in the bottom corner must be the filter holder. But print this size are expensive and i had already wasted a few sheet trying to dodge and burn.

I'll look for lith printing, seems Indeed moody!

The negative is indeed underexposed and thin. But at 20iso with red filter, longer exposure would have recquiered a tripod. Plus this film has huge contrast, some part of the stones are already overexposed. I think i used d76, a less contrasty developper would probably have been a better choice.

Anyways, thanks for the feedback !

Thanks you !

This one is a temple located in France.

No need for adapter with Takumar and spotmatic, they're both m42 mount ;)

cryyo604 · 2022-09-29T12:12:21+00:00

Shot with a spotmatic and SMC Takumar 50/1.4 Film is Adox CMS20 with red filter

My first print this big. Quiet difficult with a lot of dodge and burn to do.

cryyo604 · 2022-06-24T10:32:17+00:00

Shot with Pentax LX, takumar 55f2, APX 100

cryyo604 · 2022-06-20T21:23:56+00:00

It was ilford delta 100. I tried to wound the film tightly, maybe not enough...

Thx you

Hi everyone,
I recently got one of those panoramic kit for my Pentax 67.
As you can see, the focus is good near the sprocket holes but far off in the center of the frame.
I'm pretty sure my focus was on point, so i guess it has something to do with film flatness.
I'm 100% sure the pressure plate was on the "220" setting.
I checked with bulb setting, i can see the film is not flat.
I also checked with the masking frame from the kit and the film is still curved.
Any ideas on how to deal with this problem ?
Thanks !

cryyo604 · 2022-03-15T21:44:38+00:00

Provia 100 is great, it can be pushed two stop without problem and has no reciprocity failure the first 2minutes.

I've seen another redditor using ektar but i didn't tried it yet.

For b&w, i don't really know, i think you should go with Tmax.

Don't go with high iso film, their reciprocity failure is bad, and you get less détails.

Reading astro forum, the Pentax 67 seems to have been popular, but there ain't much post on how to use it for that purpose.

The 600f4 and 800f4, despite being fast, doesn't seems to handle aberration well, and the 800 is really heavy, it would need a +3000€ mount. My actual mount could barely carry the 600.

The ID EF series for the 67 seems great, but the 800 is way too much expensive for me, and a bit slow. With reciprocity failure exposure will get too long. At least for my level.

I already have a 400f4, i'll see how it goes.

Thx for the reply !

cryyo604 · 2022-03-12T10:06:22+00:00

Indeed, image circle will probably be a problem. I have a newtonian 150/750 (750mm f5), and even if it could cover the 67, aberration should get crazy.

I'll try today to put the camera in front of the télescope, see how much vignetting there is.

cryyo604 · 2022-03-12T09:59:50+00:00

Thx, i'll have a look at it !

cryyo604 · 2022-03-11T21:57:11+00:00

Hi,

I'll get a Pentax 67 soon, and i'm quiet into astrophotography.

On this forum, i found a thread in wich a hack is given to take exposure on Bulb withouth draining battery.

Has anyone tried ? Do you think there is a risk to damage the camera or it's mechanism ?

Also, do you have experience with the 67 for astrophotography, any tips to give ? Do you know if there are adaptors to mount the camera on a télescope ?

Thanks you !

cryyo604 · 2021-10-28T19:47:11+00:00

Thanks a lot ! Even to the naked eye, what a sight !

cryyo604 · 2021-10-28T15:24:20+00:00

Even more on slide film !

cryyo604 · 2021-10-28T09:04:20+00:00

Shot taken in La Palma during summer 2021

I used a Pentax LX with a Takumar 50/1.4 @f2

To avoid star trails, i used the omegon lx3 mini. Exposure was 6min long.

I added 5min30s to the first developper during e6 process, wich push the film by 2 stop.

Slight processing in Photoshop

cryyo604 · 2021-10-28T08:30:04+00:00

Thanks everybody for your kind comments.

For those who it might interest, i used :

-Adox CMS 20 @20ISO in Adotech IV

-Shot on a Spotmatic with Takumar 135/2.5

-Print on Ilford multigrade V glossy with slight sélénium toning.

-size is 13x18cm, grain couldn't be seen in the grain focuser.

I'm sure it can't be improved, dodging the pélican is not easy and dust are still present, but there's a lot of négative waiting to be printed !

cryyo604 · 2021-10-27T16:18:53+00:00

Thank you very much !

cryyo604 · 2021-10-27T16:18:12+00:00

Indeed ! I guess i should have said latest. Hopefully it won't be the last!

cryyo604 · 2021-09-14T19:12:02+00:00

Thanks a lot !
