Eclipse

 Soon an annular eclipse of the sun will  be seen in many area of the world.  If it isn't obscured by clouds, I will see it May.21in my area.
 As for Eclipse,　Mitsubishi motor company had discontinued it's coupe "Eclipse" last year. I can't understand why it had such the name. But Mitsubishi motor company was eclipsed. Probably,it maybe means "supersede". Three Diamond Mitsubishi were famous for "Zero Fighter WWⅡ". Mitsubishi is a weapon maker too. Eclipse might be a solar weapon. Legendary Ancient Queen "Himiko" fell from power because of  a total eclipse. It is thought that traitors devised this ultimate weapon. Since then, Eclipse happens by this mystic weapon.
 Of course this story contains a joke. Joking aside,  an eclipse would be associated with supernatural power by ancient peoples. it is true that an annular eclipse will be visible soon. Don't see  the sun directly  without eye protections.

Let's Try "How many megapixels?"Negative Film

"Maybe 5or6 megapixel digital camera, 135 film equals to"We often heard and listened to such the review or a sales promotion for digital cameras . To say the fact, I had no interest in photograph until a few years ago,  I didn't know in practice how resolution a camera film has.
 Having been bored with digital camera, (digital camera photography don't need the skill so much, mastering PC imaging aside.) I began to use film cameras. I have no film scanner, but I got to substitute digital cameras for a film scanner.  And I found negative film have far more performance than what digital camera promoters had said.

 This film is Kodak PORTRA160.(135 negative film)  Lens ; Cosina Zeiss PLANAR *T 50mm
Can you see the black rectangle line? This area became to the next image.

This image's resolution is far better than  a common flat head scanner.  This image has less area than one hundredth of original. One line equals to 2 pixels. This image seize is 487×328, and depending on lines in the image. Perhaps this image maybe equals to 200,000pixels.

 In conclusion, This trial shows 35mm negative film's resolution estimated 20 megapixels or more over. .

 Left image is a set for microscope digital photo made by myself. (Nikon Pronea Lens and Canon S95, light box, anti-newton ring acrylic plate, so on)












I didn't know how small detail a film can capture.  When I knew the real performance of negative film, it was due to be dismissed in any place I went.　And now digital camera are getting superiority of the resolution to a film.

The more pixels, the less business

For many photographers, as a matter of fact, digital camera performance might not be so important topics. Day by day, new digital cameras show up and implemented higher performance we have never seen before.

 But unfortunately, many pro cameramen are losing their jobs in Japan. Especially, publishing and advertising business are reducing needs of photograph and can't afford to pay cameramen. How about web business? It's almost child errands. I have not heard "Web business is lucrative"at all. Digital camera enable us to take photo easily, and client often do without extra cameraman.

 I got a nice idea! How about being paid from a cameraman? Nowadays even many girls want to be a camera(man or girl?). They should pay clients to take photo. Do you know a self publishing? Photo publishing will do same as it.

 In a used camera shop, I often convince that some cameraman closed their business. Tools of his trade is on sale together.
 May the glory of 80's  come back to photograph business ?

Amazing new Nikons ?

Nikonians might have been surprised at "36.3 megapixel new D800".  I wonder why not a few Nikon users praise "high megapixel model".  Until now, many Nikon users have critical opinion against "high megapixel race "among digital camera makers at least in Japan.
For example ,SONY has already released 24megapixel α SLR and Canon surpassed over Nikon at high megapixel race. But oddly,Nikon users used to say  "High pixels don't always have high resolution." 
 This is the very amateur camera collector(not photographer )opinion. Why digital cameras for professional need to have huge pixels? The Answer is very simple. Offset gravure (175 Lpi) needs far more pixels than amateur hobby printing on the condition of same resolution.  Even D800, it just only satisfy needs of B３(364mm×515mm) seize poster. If You want to get print fitted camera, a medium format film camera is still cheap and useful. I recommend you to take negative photo print. If you want to issue many copies, you can upload it as a sample with the original negative film to a print service provider.　Even 135 film, it can satisfy A3 seize printing.
