Baker Geek

I love to bake and I am a geek. Welcome to Baker Geek

This site is about sharing my passion of baking and includes recipes with step by step description. You will find for example recipes for madeleines, financiers palmiers or croquembouche; sometimes, the recipes will be broken down in large chunks, for example to make palmiers you need puff pastry, so a post will be dedicated to making puff pastry.

It also features non baking related articles, which i will list in the “geeking” category.

Enjoy.

Negative scanning

In a previous post I wrote about going back to black and white film; i got a new old film camera, shot a few rolls of Ilford HP5+ and processed them.
A crude way to get a better idea of the photo i learned when i was spending lots of time in the darkroom is to look at the negative from the emulsion side at an angle so the silver halides are mat and the rest of the film is shiny and you can kind of see a positive image.
Without a darkroom, my options are to bring them to a lab to print or to scan them and handle them as digital files.

There’s an app for that

My first attempt was to take a picture of the negative with my phone and to use an app to reverse the black to white. It proved difficult to find a correct opaque background and be perfectly horizontal to the film so the result, although it allows to see the image better, is not usable for anything else.

Film scanner

I had a film scanner a long time ago. A Minolta dual scan. it uses a scsi adapter with a DB 25 connector. Modern computers do not have scsi, and the scanner has a 220 V AC power input, also it scans at 2700 dpi one exposure at a time, 3 in one direction, then one needs to flip it to do the other 3. So i was on the market for a new film scanner. I had used a plustek in the past but I found that people were reporting good results with epson V series scanners. After an unsuccessful attempt to buy one on amazon (scanner arrived damaged with missing accessories and no power adapter so i could not confirm it worked) i found another one on ebay for $80. Note that shipping can break the deal on these as many listing read $40 or more for shipping costs.
The scanner I got is an Epson V500. Physical resolution is 9600×9600 dpi so at highest resolution it would output a 13,606 x 9,070 pixel bitmap from a 35 mm exposure (24x36mm). It also has dust removal, and Digital ICE (infra red channel to remove scratches; I don’t think it can work on black and white film though). It comes with holders for 35 and 6 x 6 cm negative and one can find other formats or alternate ways to hold the negative on ebay (some of them 3d printed). It seems they use a series of holes on the holder so the scanner software can recognize which holder is being used.
Epson driver scanning software in available on Epson’s website and works well with windows 10 64 bits. With the proper film holder, the scanner can convert 12 exposures unsupervised, each cropped, rotated (you need to select than manually but all before starting the scan) and exposure-adjusted. I scanned at 4800 dpi as it seems sufficient based on the size of the silver grains and going to 9600 would produce really big files and would take a really long time to perform.

I had to cut the film is strips of 6 so I had to get some binder negative sheets. To make a contact sheet, I used ACDSee that can easily compose all the images in a grid and put the file name (which is the exposure number) below. It does not show the film spockets but is perfectly usable.

Next step

I have read mixed reviews of VueScan vs Epson scanning tool for the Epson V500.
I may try a demo version to see which I prefer.
I will also spend time on Paint.NET, photoshop and lightroom.

Back to Black and white photography

Twenty years ago, I was doing a lot of photography with Nikon cameras and was spending a lot of time in the dark room.

Then I got married, had kids etc. Around 2000, I moved to digital and got an Olympus E-10, an SLR (it used a semi transparent mirror so it could take a picture while the view finder was still usable.) then went back to nikon cameras, this time digital, first DX, then FX.

Because of the lack of time and darkroom, I gave up black and white photography and my equipment sat quietly in a box in the basement. I gave my film camera (Nikon F70) to a cousin and kept my other older cameras: Nikon FA and FG and abunch of older lenses. I had a few rolls of film that I forgot to put in the fridge or freezer that are now 20 years old (I read somewhere that i should expose 1 stop extra for every 10 years), some chemicals that are probably not very effective anymore either and some 25 years old paper that is probably also going to be very slow now.

At the end of last year I found that I could get an F4 on ebay for fairly cheap (around $130) and over Christmas I shot 3 films.

Let me tell you how it went, what I used, the results and what I am going to do next.

Getting ready

So, I had most of the equipment but I needed some film and chemicals.

Film: I got a 100 ft roll of HP5+. it’s Ilford film rated at 400 that I have used a lot in the past. Nothing fancy but I could compare to past results. I also got 10 empty cassettes ( $1.25 each). I could have just purchased 36 exposure rolls but i though if I am serious about it, I will save money soon going this way. A 36 exposure roll is about $7, 100 ft was $75 and I should be able to do a lot more than 10 rolls and also, it allows me to make shorter rolls if I want. I also had to get a black bag to roll the films ($12 amazon). I did not bother with a daylight loader.

Chemistry:  I had some old chemicals leftover: almost a gallon of fixer but it felt gritty, a bottle of ilfosol S and some old tetanal developer as well as a box of emofin, a 2 stage powder developer. I had a bottle of kodak stop bath; i think i got this one on craigslist about 20 years ago. I assumed it does not go bad.
I wanted to start fresh so I got a pint of ilfosol 3 (film developer $10) and some rapid fixer (liquid concentrate. 1 liter $10), a couple of empty liter size bottles ($4 each). I got it from BH as amazon or ebay shipping costs were horrendous for these chemicals.

Other equipment: I already had a 300 ml graduate, a film squeegee, a thermometer and a developing tank.

Rolling the films

I started by rolling a few films. I bought new cassettes as I was not sure the 20 year old felt would still be light tight. I used to roll film in a dark room; rolling them in a black bag is very possible but it was a little cramped and difficult to measure. I taped the film to the spool and rolled until I thought i had a reasonable length. It ended up being about 22 frames on the first roll. I am not packing it a little more.

Exposing the film

I loaded the F4 and the FA with some HP5+ and shot family and landscape in the sequoia national forest over christmas. For some reason my Yongnuo flash was not recognized by the camera. Shooting at 400 (without Auto-sensitivty) takes some getting used to. I used a 50 mm f/1.4 and a 28-70 f/2.8 lenses. I had not taped the first film enough and in the FA, i wound it too hard, so I had to take the film out from the camera in the black bag.

Development

Back home I processed the films.
I found the technical notes for the dev and fix on ilford’s website.
In the black bag, I cut the end of the film, loaded it on the developing reel, put the second empty reel on top and closed the tank.
Mixed rapid fixed 1+4 (60 ml +240 ml water) and put it in a bottle.
Mixed stop (label reads 16 ml per liter. i used a teaspoon per 300 ml.
Prepared ilfosol s at 1+14: 20ml developer+ 280 ml water at 20c. the developer will not be reused so i mix it last and leave it in the graduate.
Poured dev in tank and start counting 11 minutes. 4 inversions during the first 10 sec of each minute followed by a tap to get rid of bubbles.
At 10’50 mark started draining dev in sink, poured stop, shake, pour stop back into its bottle
Add the end of the film that had been cut from the roll in the opening of the tank to check fix action; poured fix and same 4 inversions in first 10 seconds of each minute for 2 minutes only. Checked that the piece of film is clear after the first minute.
Poured fix back to bottle, rinse with water. rotate 5 times, replace water, rotate 10 times, replace water, rotate 20 times. Added a drop of wetting agent, and water, final rinse and finally open the tank and breathe.
Ran wet squeegee over the film, and put it to dry in the shower with a cloth pin at the top and at the bottom (as a weight)
Wash and dry everything.
Look at the film from the underside at an angle to see it in positive.
Repeat with the other films. For the other two films, i got more daring and processed them together (so I had to make 600 ml total of stop and fix)

Scanning

The film is now waiting to be scanned. I tried to take a photo of the negative with my cell phone and use a negative filter. the quality is clearly not there. I have ordered an Epson V500 scanner. I bought an olympus film scanner 25 years ago but it uses an SCSI interface and i don’t have the computer i used then nor the SCSI adapters or drivers. The Epson flat bed scanner has a led lit back and scans at 6400 dpi which should work fine.
I will update this post when I have had time to scan the film and will post some pictures.

 

Conclusing

Getting back to black and white was fun and brought many fond memories.

Taking the photos required a slower process than using a phone or even a DSLR as you only have so many exposures per roll. The F4 can do something like 5.7 frames per second, so the film would last 5 seconds. The FA does not have a motor. I used them in P mode most of the time; I want to try the S (speed) and A (aperture) modes. I also scored a Nikon FM on ebay for $40. The meter does not work but i think i can fix it, and the FM has a mechanical curtain so it can still work with no battery.

Processing the film was as I remembered it. Quiet alone time, when one has to pay attention to not miss any step or miscount the processing time. Seeing the processed film for the first time is still a great feeling.

I am not sure if it will be happy with scanning and printing the photos as a digital file or if I will want to convert the basement into a darkroom (or if my wife will let me.) There is a great lab not far from home that does black and white printing. There is also a camera store that has a darkroom one can rent by the hour. The question is will I have time to do it.

Toyota remote and transponder programming

I got used (2007) Toyota Camry.

It came with 2 keys, one of them had the hook broken. The key has a transponder and a remote in the handle.

I did not feel like paying $200 for a replacement key at the dealership.

I found that one can get a key shell (on ebay). The key will need to be cut but the transponder and remote can be moved from the old shell to the new shell.

I also found that full replacement key are not a lot more expensive (about $20) but will need to be programmed.

A local locksmith offered to sell me key clones (without the remote) for about $60. The key with remote was more. He also offered to do just the programming. i don’t remember his rate but it was $50 or $100.

I found on ebay and amazon some key programming tools. They run $15-$20.

After ordering and receiving everything, i asked at OSH for the cutting of the key. I know that locksmith typically charge more for auto keys are they are usually stainless steel and require a key cutting machine that will handle stainless steel. OSH quoted me $3 per key for just cutting them.

I was at home depot, and i got them to cut it for free as they don’t have a sell code for just cutting.

Programming took some patience but worked well. i was worried to brick my car.

Using the instructions on the programmer and youtube, i could figure out how to program both the remote and the key to my car. Or more correctly how to program the car to like the remote and the key transponder.

If you try it, the key is to be patient. Programming the remote was easy and quick but the programming of the transponder took a good 30 seconds; on my first few attempts, i was not patient enough and thought it had failed and interrupted the process early.

All in all, I saved over $350 and have a programmer to program more Toyota car keys.

The tool i got : “OBD2 Auto Remote Key Programmer Maker For 96-15 Toyota G and H Chip Scanner Tool”  A green case with a switch for programming either the remote part of the key or the transponder. $23.49 including shipping.

The keys i got: “2 Remote Keyless Entry Car Key Fob for 2007 2008 2009 2010 Toyota Camry hyq12bby” $18.49 including shipping.

The key shell: “Replacement for 2007-2010 Toyota Camry Sedan Remote Car Key Fob Shell Case”  $4.70 including shipping
