Is that german building Mader's over on 3rd st? Great photos, if you're looking for other spots you might try over near Kadish park/Kilbourn Reservoir park. Might be some good angles overlooking downtown from North Ave,  although its been awhile since I've been over there.

How long of an exposure are you using for these shots?

I was kind of wondering about this as well. The sky seems to have a lot of color to it. I was thinking maybe these were taken not long after sunset... maybe half-hour/hour?

there is a lot of ambient light in this area, so the exposures were from 5 to 15sec, at ISO400 f7.1

these were taken about 9pm. it was fully dark outside (besides the moon).  in my experience, the sky is always blue in long night exposures. from what I read, there are several things that affect that - the moon, time of night, light pollution, etc. i've never had a greyish black long exposure come from the camera. shorter exposures do tend to look greyish black.

my process is this - set the camera to an appropriate aperture (f7 to 9ish for 'landscape' scene) and low ISO and let the camera expose the scene. what will happen a lot is it will expose the maximum time (30sec on my particular camera) and the scene will still be underexposed. i then crank up the ISO until I get a reasonable shot. after getting a close exposure, i use exposure compensation to dial in the exact amount. that will make the camera add or remove a second or two from the exposure.  if its REALLY dark out and there arent many light sources, you'll also have to crank the aperture open

also a sturdy tripod and using the shutter timer (or remote) are 100% necessary for exposures these long. you still can handhold night shots, but you'll have to use a big apertures (like 1.8) and high ISO to get the exposure times down. 

for example, this shot was handheld. It was shot at f2.2 IS01600 with a 1/4 sec exposure. even at a 1/4sec i took several photos to get one steady enough to be sharp.

and for funzees, here are some non-car long exposure night photos I have taken.

That makes sense. I didn't realize you were using a tripod. I don't like standing around or having to interact with passer-byes that want to start up a conversation, so I'm more of a run-n-gunner. Shots like that make it look like it might be worth it though.

Lets go take pics tonight!  The blackness of my paint will tie in with the blackness of everything else!

 

I'd like to see a long exposure needle sweep photo of a tach. Im sure my temperature gauge would have a nice needle sweep too if we wait long enough.

black should be interesting! i'm free tonight, hit me up.

ok e30 guys, need some help.

my aux fan stopped working a couple months ago and ive finally got around to addressing it. the fan ended up being fine, i think my temporary wiring failed at some joint. anyways, i moved to step 2 of temporary wiring to solve it. i've got the system setup as follows:

4-pin relay.

1. Input power from main positive battery terminal in engine bay, with 30amp fuse inline.

2.Output power to Spal fan

3.Switch power from aux fan wiring (12v on ignition)

4.Switch ground to main engine chassis ground.

the Spal fan ground then goes through the single temp (82c) switch i installed in the radiator, which then goes to chassis ground.:

so, this all works great and the fan did switch on when the temp switch got hot enough and the car cooled down.  however, the fan kicked on when needle on the gauge was about a needle's width shy of red. i assumed the lower temp (82c) would get the fan going sooner than that. it seemed to me that the top right corner of the radiator was cooler than the rest of the radiator and that may be why it happened. i've never actually owned an e30 that had working ac, or that overheated in any way to have the AUX fan kick on, so this is new territory for me. is it supposed to kick on that late?

The sensor is sensing the cold side of the radiator which is essentially the coolant supplied to the engine.  I've had great results with an 80/88c low speed/ high speed switch on multiple e36s but on an e30 I tried it on it seemed late to turn on and the e30 fan isn't as good as e36 aux fan (spal should be better though).  I was uncomfortable and reinstalled the mechanical fan.  I didn't have a real temp gauge though so I am not sure what the temp really was.

the 16" spal fan does work great when its on. you can see the needle fall almost instantly. there is actually no room for a mech. fan with the 24v swap, so that is not an option. 

i think i might have to get a

to check real temperatures of the radiator and engine.

Is the temp sensor m12x1.5 thread?  If so you could use an e36 temp switch which is available in an 80c.  That is what I have in my e36 and it works great.  I have an Autometer gauge and the fan turns on around 210F at the cylinder head temp port.  I have a Spal 16" and it brings the temp down pretty quick and shuts off.  Pics here.

A tempgun is probably a good thing to try since I don't necessarily trust the factory gauge to be accurate. The temp switch is at the coldest part of the cooling system so it makes sense to me that the engine itself gets pretty hot before the fan kicks on. Admittedly I have a different engine and an e36 radiator, but for reference the head temperature (reading data from the ECU) on my car is about 210 when the fan kicks on with a 91C switch (61311364272).

From the factory, the aux fan on the e30 is wired through relay k1. The temp switch AND the A/C button can turn on the aux fan by applying 12V to the K1 relay. If you turn A/C button on, the fan automatically runs too (vice-versa with the temperature switch). Something doesn't seem to add up with the switch and the temp gauge. As others have stated, find the real operating temp and go from there. -Nick (Nice car BTW!)

well the journey of this car will be wrapping up next year. as i pull the car into the garage for the season, it's with the intent to fix a couple things over the winter and post it for sale in the spring.  wanted to say it out loud to help make the idea real.

I'm finding myself drawn to other hobbies instead of the car. Also, I'm getting weary of maintaining 1 bazillion motorized appliances. The list has grown and needs to shrink somewhere.

This makes sense.  You've done a nice job with the car thus far!  It's hard to maintain a level of interest in multiple hobbies when time and money are finite for most of us.

It makes sense. The car hobby is a fulfilling one but in a lifetime of limited resources, it can be a hog.

Just maintaining 3 reliable vehicles is a chore in itself.

i will still be car hobbying, just on a limited basis. an engine tune or set of wheels here or there. but one vehicle for me only. i've been driving the volvo a lot even in the summer,  sometimes even choosing it over the e30 for the turbo noises.

I'm jealous of your woodworking projects and you're more sane then I am to make these decisions. Don't be a stranger once this car flies the coop. 

sane = overly pragmatic.  i try not to cross the line from sensible to boring, but i definitely do sometimes, lol.  

I get more joy from the home projects since it makes two people happy (me and the wife) and more people get to enjoy it (friends and family). plus, hobby time all year means a nice, warm, well lit, indoor shop space.

Happy wife, happy life is a myth.  You've already figured it out.  Doing something for other that also brings you joy is far more rewarding.  I will most definitely sit and watch woodworking and cooking shows on PBS when I have the time.  Skilled woodworking is amazing to me!  The way they fly through building hidden joints and chiseling out perfect dovetail joints is just nuts.
