    Replacement for DP1M?

    I thought I found a replacement for DP1M in Leica Q, but the latter had the EVF failed in a week, and it went back for a refund. It's quite sensitive to Miami heat and humidity even in moderate exposure, I guess. Unlike my DP1M, that keeps clicking for over 2 years, and DP2M - for over 5! Some qualities don't get mentioned on a spec sheet.

    I thought it was a new bike. BMW is starting to offer more options to customize new bikes. The rear shock placement looks modern compared to the R80 which had 2 shocks on the rear posts. I think it looks great.

    I'm clueless about bikes. This one caught my attention through a window of a gallery and I paid a visit. Unfortunately, I didn't inquire about the model name and year, but did try to research after revisiting the shot at home. The closest match I could find is the 1980s R80 and what tuning companies like Rockerbox and Diamond Atelier can do with them.

    Definitely shares lines with the old R80, but pretty sure it is a modern bike. Too many cues that only modern bikes now have. Would love to ride that one, looks like fun. At my age now, the Ducati is getting to be a bit much. Thinking about a lighter and less powerful bike.

    IMO its an older one, the newer have only one arm at the rear and a vertical absorber, this horizontal absorber with the two arms is an older custom thing.

    That 2-valve monolever engine is a giveaway, isn't it? BMW does not make bikes with this engine anymore since 1995, afaik.

    I don't know what a monolever engine is, but if you look at the inverted forks, M Power label, modern discs and calipers, it is either a newer bike or a custom job as mentioned above. The drive shaft and heads look older for sure and if those are carbs, then again, for sure. In any case, good looking bike and nice picture.

    Thanks,

    I bought a DP1m recently for a nice price to convert to full spectrum. I took some shots before the conversion to get a sense for the camera's output

    Here's a link which provides a lot of information about full spectrum and infrared shooting:

    https://kolarivision.com/articles/fu...um_conversion/

    It basically involves removing the IR/UV cut filter (aka hot mirror) from in front of the camera's sensor so that the camera can see a wider spectrum of light.

    The SD DSLR cameras and the SDq have an easily removable hot mirror, but the DP cameras obviously require getting into the internals with a screwdriver to access the sensor. But I wanted the small size of the DPm! Kolari will convert the DPm cameras for $200, but I found some explanations of how to do this so I just did it myself. I have some pictures of the process to share soon. I thought the process could be reverseable with the DPm, but some of the screws were threadlocked so I had to break the hot mirror to remove it. It is possible to add an IR/UV cut filter in front of the lens, but these aren't quite the same as the one in front of the sensor so the final output is still somewhat different. I don't have one of these filters yet--just what I've read.

    A couple of visible spectrum uploads today. Not a big fan of the bokeh of this lens, personally. It's a bit busy in the edges. But the 28mm equivalent is perfect for IR shooting which was my intent with the camera.

    Re: Sigma DP1 Merrill Shots

    These images are from the process. Here are the threads on DPR that I followed with more detail first thread to remove the hot mirror and second showing how to get under the hot shoe.

    The hot mirror that I removed is the "red" glass here. It is actually cyan when removed, the red is a reflection. From the first instructions, I thought I could remove the mount here, but the screws were threadlocked with something, so in the end I broke the glass to extract it. It's easy to do this accidentally I think since the glass is only 1mm thick. Then just peeled off the rubber glue. Obviously, this is not reverseable

    And finally some DP1m images. First, before modification:

    After modification and custom white-balance, full spectrum results! I made some exposure/contrast tweaks to the images below, but no channel swapping or large hue adjustments. It looks like these out of camera with no filter. One big benefit of modding this camera compared to an SD is you can see the IR results in live view. Adding various color filters and infrared filters can yield different looks.

    Capturing Infrared in the Alternate Forum would also be a great place for these.

    Ah, thanks for pointing me to that thread

    I will share some images there. I picked up some color filters to play with, and will have some more to share soon.

    One more full spectrum shot. Fun to see the yellow come through pretty much normally here.
