What do you choose from the colored acid cans? ..

The number of people trying to enter the field of color development at home is steadily increasing, and the reasons are well known, as we find the majority of photographers now and they limit their work to color film, the golden age of black and white film has passed, and even new entrants to the field of photography start with color immediately.
Since the mid-seventies, we have been witnessing the emergence of many new chemical packings that make colored acidification almost as easy as black and white acidification.
It is true that commercial color development laboratories cater to most people, who have neither the time nor the inclination to do so on their own, but more and more serious color photographers want the images they create to be under their control.
And their full control from here takes the content from their films, negatives, and slides to a dark room inside their homes to process them there instead of sending them to a commercial laboratory.
In any case, it remains that some are deterred from that, thinking that the colors are difficult.. and they are in fact
It isn't - it's true that we would need some precision about time, temperature and cleanliness, compared to what we do with black and white, but this loses being a real dilemma with practice.

Add to that the cost of setting up a darkroom at home, Patterson's colored darkroom, which costs the equivalent of £140, will of course discourage some people from joining the self-bleaching circle, because we're all on our budgets. The basic equipment is almost like .
Another nuisance is the confusing stacks of colored developer cans and bottles on the shelves at the photographic store.

The main objective in this article is to give instructions about the available packaging, what to do and what is its cost. The prices given are only approximate, because we will find discrepancies between seller and seller. And the price we quote is closer to the average.

Which path do you take? ..
The first decision you have to make is whether you are going to work with a print movie or a slide movie. For the serious photographer who hopes one day to find his colorful works published or displayed, slides come to be his best choice, because most magazines do not accept publication except from slides. The only drawback with slides is the need for a projector or viewing device to show them to others.
The printing materials, on the other hand, are ideally suited to those who want to send their pictures here and there, and to hang enlargements of their masterpieces that are now and then realized on the walls.

colored negative:
Making a color print includes two stages, the first is the need to endorse the exposed film to produce a set of negatives, and the second is the need to enlarge and print these negatives on paper.
There are three main types of packages, some of which show only the film, some of which only prints, and some of which are comprehensive, that is, they do both.
If we wanted to make a print of our negatives, we wouldn't be profitable if we did the work ourselves. There is no doubt that this work is fun and satisfying - but the costs will not be in our favor when we make 24 prints ourselves, we will save more by sending the film to a commercial laboratory, because the cost of the necessary materials alone will exceed the amount paid if we printed the film at home. Then we may consume the rarest and most important resource - time - to produce good quality enlargements.

Only C41 negative:
There are still a few packages that will show C51 films in the standard black-and-white negative process (compatible). They are effective cans, they work well, and they give good results, but we really can't recommend them to the average home developer who does mediocre packaging and the holistic can is a much better proposition.

Akva (AP70):
For films of the type (C41), and the instructions related to it are almost the basic instructions that you find 26 (AP70) is a triple bath process that comes with the packaging in many languages and the cost is acceptable when it reaches the equivalent of 4.5 pounds for a container of 500 milliliters, you can develop 6 rolls 135 -

Kodak Flexicolor:
A box of 500 likes will process up to 16 films and costs about £10.80. As with the AP70, the acidification period is traditional at 38°C. This cost is not particularly good when compared to some of the bulk packs available.

Comprehensive packages:
- Photocall II
The Photocall II universal tin is one of the most important in the home baking industry, it's a one liter tank that costs just under £10 and can either endorse 15 rolls 135 - 36. Or print up to 60 prints 10 x 8 inches.
The box also includes a great 16-page instruction booklet that covers almost everything you need to know. Most useful here is the What Went Wrong clip that solves any dilemmas you encounter.
It is a simple two-bath process that can be carried out at a temperature of 32-40 degrees Celsius for films - and 25-38 degrees Celsius for prints. Also, time periods are given for the development of modern black and white films that generate dyes (chromogenie) such as Ford (XP-1) and Acva Vario (XL). This, despite the fact that the chemical compounds are inclusive. It needs an additional element present in the box, of course, to prepare these chemical compounds for the development of the print.

Patterson 2NA:
The main advantage of Patterson's new product is that it is really comprehensive and does not need an additional element when it is used for printing, hence the name: (NA) from (No Aditive), meaning that there is no additional element.
This is also a double bath process. Well packaged with clear easy to read instructions.
As for sizes and temperatures, they are almost the same as Photocall II: 135/15, 36-32 up to 38 degrees Celsius - or 60/10 x 8 inches - 25 up to 38 degrees Celsius.
Prices vary, but you should find this can in stock for around £9 for a one-litre can.
In fact, the field of comparison is narrow between (2NA) and “Photocall II”. Both are of the first class. They give great clean, detailed and saturated results.

Print only:
There are now a number of packages designed to print only on paper. This is typical for the photographer who sends his film to be commercially acidified and only wants to make enlargements, as well as for those who practice the work involved in a lot. It is better for the latter to buy separate chemical compounds to endorse the negative and the print.

Akfa Process (92):
Akva (92) is a traditional process based on two baths, and operates at a temperature of 33 degrees Celsius. The cost of one liter per gallon is approximately five pounds sterling. It will acidify up to 24 prints 10 x 8
inches, and there are economical measures, it is a capable and effective process, but modern appearances have replaced it in many areas.

Kodak Ectaprint ( 2 ) :
Ektacolor (74RC, 78RC) and other similar Kodak developing papers are designed, but are very expensive as a one liter can sells for about £13 and produces just 24 10" x 8" prints.

Patterson (2CP):
Although it was originally intended for use in automated developer, the 2CP remains typical for those who make many prints of negatives.
It is a quick two-bath process typically suitable for tray endorsement. A basic box costs about £25, which is nevertheless good value as long as the box in question can produce 200 prints, 10 by 8 inches.

Fotocular RT Printmaker:
The biggest development in color production was the advent of a two-bath passive process that allows you to work under normal temperatures.
What Fotocallar offers is (RT), which means (Room Temperature), which means the normal temperature of the room, and this allows you to work under any temperature within an amazing range from 15 to 40 degrees Celsius.

However, from a practical point of view, it is advisable to choose a working temperature between 18 and 30 degrees Celsius. I opened
At a temperature of 20 degrees Celsius, the time period is reasonable, which is five minutes and forty seconds, but under less than 18 degrees Celsius, the period increases greatly, and if the temperature exceeds 30 degrees Celsius, the period becomes too short to allow reasonable control.

It should be noted here that the whitening and fixation period is not affected by temperature. The minimum is three minutes, but more does not hurt.
It is clear that RT is very suitable for acidification in a tub, but it can be used just as well with a drum or ovbilal.
And when a can of one liter of it costs the equivalent of 7.5
£1, and makes 30 10" x 8" prints, getting a little more expensive than some other processes. But the good acidification under the available heat makes it worth everything that is paid for.

Patterson (2RP):
This print maker is very similar to RT in that it avoids the dilemmas of time and temperature - but with a different feature. That is, the acidification period is 3.5 minutes, regardless of the temperature, as long as it is between 20 and 38 degrees Celsius.
The box is dated, as is the case with all of Patterson's colored chemical compounds, although these compounds themselves have good stability and shelf life after opening their bottles.

Up to 40 10" x 8" prints can be produced from a one liter can costing the equivalent of £7 with partial chemical reuse [2RP stands for Room Prie 2].

Slides endorsement:
The endorsement of the slide film does not need more than half an hour, and it has the advantage of adjusting the endorsement accurately to suit our preferences. And the same is the case with colored negatives. We suggest that you carefully consider the economic effectiveness of doing the work yourself.

Depending on the packaging that you use, the least you will cost on the materials for developing one language is the equivalent of one pound, and there are many laboratories that will act on your behalf to complete the work for what ranges between the equivalent of 1.5 and 2 pounds. As for the great advantage of endorsing your slides yourself, it is that you get results within minutes, instead of a whole day, in addition to the pleasure of total self-work, of course.

Ectachrome acidifier (E-6):
It's a rather old-fashioned multi-bath box and very expensive too, at about £20 and developed for only ten films, the cost is about £2 per roll.

Agva Process (44):
ACVA (6 E) gives good results. But the work goes through many stages, as it needs five separate bathrooms, and a 500 ml package that gives four languages of acidified film at a cost of approximately 7 pounds sterling.

Ford (6-RP):
With (6-RP) we go down to four-stage acidification, and the results are of the same quality in everything as in other processes, but the cost is considered high when the price of the instruction concerned with five films reaches approximately 9 pounds sterling.

Parven (CRX-E6):
This Parven box, which is based on four bathrooms, is more economical. So, the 600 ml can handles a year of films at a cost equivalent to 7.50 pounds, while the 1200 ml can handles 12 films, compared to the equivalent of 11.95 pounds sterling, and this is a very reasonable price.

Patterson (3E6):
The biggest development in home slide development was the recent production of the Three Pigeons can.
The basic acidification temperature here is 38 degrees Celsius, but the time periods are given for a decrease of up to 20 degrees Celsius. Beware of the effect of such low temperatures on the quality of the image in an exacerbated manner, with the appearance of a strong yellow color tinge (3E6) is typical for raising the rating (4p rating).
This, Patterson (3E6) comes in 600 ml cans containing six films 136-36 at a cost of approximately £8.50.

Photocall Chrome - Six:
It is one of the classic slide packages that now comes in the form of three doves, and like (3E6), it can be used under temperatures from 20 to 45 degrees Celsius, except that the conditions remain the same. And to get the best quality. Stick to a class of 35-38 degrees Celsius.
A box of 600 ml costs the equivalent of 9 pounds sterling and handles 8 languages. As for the 1200 ml box, it costs 12 pounds sterling and treats 16 rolls.
Assuming you don't have to throw away any chemical compound, your development will cost down to the equivalent of £1 per roll.

Print from slides:
For those who like to take slides, whatever their reasons for doing so, there must be times when they want to make a print. This is one of the cases in which it is very desirable to practice the work yourself.
From slides - which are made commercially, they often come in moderate to transitional prints - quality prints, unless you are prepared to pay a lot for them.
There are many processes for creating a version of Slide, all of which give good results, but with varying advantages.

Chromium phototechnology (R):
Recently, Photochrome (R) has been replaced by Chrome (R), and is used with recent papers. Reflectivity Kodak Ectachrome (R) 14 and 22 This is a three bath process that can be accomplished at temperatures between 20 and 40°C but 30°C is best with a 10 minute development time This Chrome (R) canister will print 20 prints of 10× 8 inches at least, and it will cost you the equivalent of approximately 10 pounds sterling.

Sipachrome (11-A):
Sepachrome is certainly the most used for color printing in the slideshow process, and for good reason.
This is because the cans have their competitive prices - one liter of which costs the equivalent of 6.80 pounds
sterling, makes 24 prints 10 x 8 inches, and the two-liter tray makes 48 prints for the equivalent of 11.50 pounds. The basic working temperature is 24 degrees Celsius, which is easy to maintain, but the periods can be adjusted for a range of 20-29 degrees Celsius.

The paper itself has a huge range in terms of exposure and color balance. The pigments are also very fade resistant, which makes them ideal for display.

ecvachrome speed:
It's the latest addition to the series of prints from Slides, and was initially hailed as a miracle solution, getting a print finished in just 6 and a half minutes. Just a minute and a half in activator and five minutes of wash-and-air-dry. Looks like this. It's all too good to be true, so what's bad?
The hurdle here is cost. Ten strips of paper measuring 10 by 8 inches cost the equivalent of £20, and one liter of tonic costs the equivalent of £3.
However, the tonic is chemically stable, and therefore it remains effective with intermittent use, but be careful while you work with it. It is a substance (14 Ph) very caustic! . Acfacalar, Speed is unique among color printing processes in that it allows for an amount of adjustment of the light contrast. It is enough to add water to increase this contrast, or increase potassium bromide to reduce it⏹

⏺Style:
Not so long ago, almost all home color development took place in printing drums, and the intention was to use as few chemical compounds as possible to develop the print.
By placing a small volume of liquid in the usually 60 ml container of an 8 x 10 inch drum and keeping the drum rotating - either by hand or with a motor - the chemical compounds will remain in constant contact with the print.
A flat tray on a rotating base, and since you need a wide space to practice rolling effectively. Patterson came up with the ingenious idea based on the existence of such that the chemical compounds remain in contact with the face of the print.
It is a rotary acidifier that occupies a space less than the space it occupies throughout, and there is an optional motor that removes acidification from all its difficulties.
The advent of instructions that operate under the normal room temperature witnessed a shift towards a colored print closer to the black and white style; In trays, using the dishes is much easier and in many ways you don't have to work constantly.
To wash and dry the drum or rotary acidifier after each print. You can also easily acidify prints with irregular scales. The downside is that you work in complete darkness, with unpleasant chemical compounds most of the time. You also need to make sure you produce enough prints within the working life of the solutions⏹
