Thread Title: Optimal iso

Gerard Blair   Gerard Blair
https://photonstophotos.net/Charts/RN_ADU.htm
So here is an interesting link. It purports to report on noise analysis for multiple cameras and for instance if we look at my camera canon 6D mark ii, we find that iso 100 is not the least noisy setting: if I stick the camera at 320 I get better noise elimination and 5 more stops I could apply to the shutter speed ( for the same brightness).
I tried an experiment and I convinced myself that there was at least no degradation at 320, but I am biased by hope. I got this hint from a speaker at the local club, and I think I understand the claims of this site, but does anyone have an insight as to whether or not this is a valid conclusion?   Posted: 04/24/2022 11:19:42

Thread Title: shout out to Peter

Gerard Blair   Gerard Blair
Peter - it is late I know but I needed to say congratulations. I was trolling through the PSA (PID) Creative Image Contest (to try to learn how to improve) when I saw an image that looked vaguely familiar - with Gold medal from the end-of-year - and then realized it was familiar because it was yours and was in the same building as one of your pictures we looked at in this group. I just wanted to say: well done!!!   Posted: 02/26/2022 09:07:01

Hi Gerard
Thanks for the message. Very kind of you. I think that was for ‘Reality television’ which was a creative image that has done very well in salons. Where exactly did you see it featured as I may have missed seeing it. I know it was published in the PSA monthly magazine.   Posted: 02/26/2022 12:03:28

Thread Title: 52 Frames Challenge

Barbara Asacker   Barbara Asacker
A few months ago I joined 52 Frames. Each week there is a new challenge. It pushes me out of my comfort zone, and keeps me engaged in photography. It's free and it's fun. Perhaps you are already familiar with the site. If not, click on link for more information.

Thread Title: Long Exposure Images

Michael Hrankowski   Michael Hrankowski
Barbara,

At your request I am uploading 5 of my long exposure "experiments". These are me just trying out the ND filters and using PhotoPills for the exposure calculations. The two monochrome images were taken with a 10-stop ND filter, ISO 100. The one with the three pilings were at 20 seconds and the other one at 70 seconds. The color images were taken with a 15 stop ND filter, ISO 100. The close-up with multiple pilings was a 7 minute exposure; the entire pier, 5 min; Second close up, 4 min. Long exposure works best with things that move - water, clouds, etc. I'll be experimenting more as I have two coastal trips planned in October where there will hopefully be rough water and moving clouds.   Posted: 09/23/2021 13:40:59

Hi Michael
Thank you for sharing your images and techniques with us. You were able to capture nice effects with your long exposure settings. I especially like the pier image. The smoothness of the water, and shadows create a pleasing image.   Posted: 09/23/2021 16:48:34

Hi Michael, I am enjoying looking at your long exposure images. I did not think that the reflections would be as distinct as they are. Perhaps when you post another long exposure you could also post a short exposure (almost said normal exposure) image to show some of the differences. I also only see 1 monochrome image, did one not post?   Posted: 09/24/2021 02:30:39

Randy, thanks for your comments and bringing t hat to my attention. Not sure why the other monochrome didn't upload, but here it is.   Posted: 09/24/2021 09:54:50

I like this one the best, something about the reflections of the pilings melding in with the actual pilings is excellent.   Posted: 09/24/2021 19:54:03

Randy, since you asked, here is my test exposure for the Edmonds Pier shot. To properly calculate the long exposure, I'm learning to take a "normal" test shot (or shots) to get an ideal base exposure from which to calculate the long exposure shutter speed.   Posted: 09/24/2021 09:58:40

I'm glad you posted the normal shot to show the comparison. The long exposure shows a calm day. The normal shot shows an unsettled day with threatening clouds. Different emotions are attached to each image.   Posted: 09/24/2021 11:22:45

In trying to understand the mechanism, I am thinking the effect is to average the light for each pixel over time. Which is a surprisingly analog approach on a digital camera.
This reminds me of another technique I learnt recently which is to reduce noise in high ISO images ( if you need this setting for low light conditions say) which is done by taking multiple shots and then in photoshop one would stack them and then take the average using the mean function. This eliminates the digital noise, in the same way as the ND technique eliminate the wavea’ motion.
Michael, thanks for the pictures, I love the last one, so ethereal   Posted: 09/25/2021 06:36:55

Gerard, using ND for long exposures is no different from any other blur achieved from a "normal" slow shutter speed or camera movement. It's just that the exposure time with ND filters is extended into minutes rather than seconds. Digitally speaking, I assume it would be the same as applying a motion blur filter in Photoshop. Regarding noise reduction in Photoshop - I'm not familiar with the technique you describe and I don't know how the mean function works… I'm still learning Photoshop. Personally, I rely on Topaz DeNoise. I'm constantly amazed at how well it works.   Posted: 09/25/2021 09:25:23
Gerard Blair   Gerard Blair
I have to disagree about ND being similar to motion blur - think of it this way, you could not start with a single image of waves under the pier and then achieve the clarity in the reflections by changes within photoshop. By doing a long exposure you are essentially sampling the image continuously during that time: with the grass, that causes a blur because the grass is moving, with the waves you are adding clarity because the random noise caused by the motion in the water is making the local image lighter as often as it makes it darker ... and so the average light intensity is as though the water did not move at all.

The averaging in photoshop (in case anyone wants to play) is in File->Scripts->Statistics; one day, though, I will spring for Topaz.   Posted: 09/25/2021 10:28:45
Michael Hrankowski   Michael Hrankowski
Gerard, perhaps you misunderstood my comparison of ND to Photoshop motion blur. I was only suggesting the effects at the electronic level may be similar. I was not suggesting one could actually achieve the same effect using motion blur in PS as one can using ND filters. …but then again, I’m no electronics engineer so I have to admit my knowledge of those details are pretty much non existent!   Posted: 09/25/2021 11:18:24

Thread Title: Thibault Roland Workshop

Michael Hrankowski   Michael Hrankowski
I’m really excited to attend my very first live photography workshop at the end of August. Thibault Roland (Google him!) does some amazing work. Most of his work is monochrome and he specializes in long-exposure photography. Our workshop is a 3-day event in The Palouse - a beautiful, rural area in Eastern Washington. Assuming I get some halfway decent images, I look forward to sharing some images in our group.   Posted: 07/21/2021 20:34:07

Sounds fantastic Michael. I am jealous. I am in country Victoria in Australia and we are in COVID lockdown at the moment, its our 5th one this year. I haven't been out to a workshop for 18 months. Can't wait to see some images and hear all about it.   Posted: 07/21/2021 23:22:41

Thread Title: Intro

Leanne Moore   Leanne Moore
Hi everyone, thought I better introduce myself. I am an Aussie from Hamilton Vic. I've been taking photos since the film days ....on and off. I struggle with editing images in Monochrome. I am hoping to get better with producing images through this group. So be blunt, I can take it.
I am so looking forward to being a member of this group and getting to know you all and helping each other.

Hello Group 99 members! I wanted to introduce myself. I haven't done much monochrome since my high school days back in the dark ages! I am here to improve my B & W images and appreciate frank (blunt is completely okay!) commentary and advice. Any tips / advice anyone has on editing, composition, subject matter are welcomed with open arms. I'm looking forward to my participation with you all.   Posted: 05/03/2021 10:43:45

Hi Michael,
I know you opted out of receiving server messages but I also sent you a personal email from my account last week and never received a response. Please let me know what messages you are receiving. I know you changed the original email to the gmail account. Is that correct? I may need to send you important information.
Thank you
