About this time of the year we commence to read articles on Development troubles" and Dark room difficulties," and are told how to maintain an even temperature, how to avoid frilling and fog in half a hundred different ways; how to test our own dark room lamps, how to remain happy though suffocated, and how to more or less satisfactorily dodge the troubles and inconveniences incident to prolonged incarceration in the dark room.

It is to laugh.

The sovereign remedy is so simple - Tank Development.

A year or so ago some question might have been raised as to the quality of negative produced by this method, but today the thousands of tanks in constant and successful use in studios the world over have demonstrated the superiority of this method over the tentative dark room way.

Comfort, convenience and results. These three points score in favor of the tank. The remaining point is that of economy; we have the dark room with its necessary equipment of trays, lamps, etc., so why should we spend money for the tank when we can produce good enough results without it?

An eight by ten Eastman Plate Tank costs ten dollars.

Now how long have we got to use it to get our money back, and enjoy its admitted good features without cost to us? We can, if we are expert, and willing to take some chances, develop eight five by sevens at one time, while the tank will accommodate twenty-four. The tank will develop the twenty-four plates perfectly in thirty minutes, and will demand our personal attention, not to exceed ten minutes, leaving twenty minutes to devote to other things outside of the dark room. To develop twenty-four five by seven plates by the regulation dark room method will require about four times ten minutes and demand personal attention every one of those minutes. Any way we estimate it, the tank will save one-half or more of the time spent for development and at that rate it will not require many weeks use of the tank to pay for it, after which all the economy, comfort and convenience of the tank are ours without cost.

There is no argument against the tank.

Insurance

"It isn't what you spend, but what you get for what you spend." - Yes, this is another "tested chemical" story - and if you are not interested in business insurance skip and turn over. We have spent thousands of dollars in the procuring of chemicals and in the compounding of chemical preparations that we know are right.

We ought to? - granted and more, we had to.

It is of the utmost importance to us that our sensitive products receive the best possible treatment, so that they may, in your hands, yield the best possible results. The highest grade chemicals cost us more money than the ordinary grocery store variety and they are worth it to us and to you. It is worth the extra cost to us to know that we are putting into your hands the best possible chemicals with which to work our products and it is worth the small increase in price to you, many times over, to know that you are backing up the brains and skill of yourself and your workmen with the best the market affords, and that when you have produced an unusually beautiful effect in lighting and posing, that you are not handicapping the final result by the use of indifferent materials anywhere in its production.

The best is always worth its cost.
