## film – What are these vertical lines of my negative?

I think that in general there are three plausible possibilities:

1. Closure problem with a focal plane shutter;
2. Scan problem;
3. Development problem, probably restlessness;
4. Light comes out in the camera or on the edges of the reel, or the reel is stored in a place that is very bright.

From what you said (1) and (2) can be ruled out: the camera has a leaf shutter, and the lines are on the negative.

I do not think it's (4) because the lines are too close to each other: If I had problems with the light at 120 (due to the exposed roll that sees strong sunlight), it was clear that light is coming in the ends of the light Roll and also through the backing paper in a wide band. I do not think that's it.

So I think it has to be (3): excitement or another processing problem. And while you process it yourself and paint is fussy about agitation, as it's designed for continuous agitation, I think that's very plausible. The bad answer is, "Buy a Jobo," even though they are terribly expensive (and the one I had was not electrically safe).

## 35mm – Film Negative Scanning – Resolution, DPI and File Size

dpi is about the inch … pixels per inch.

4500 x 3000 pixels at 3200 dpi are 1.4 x 0.94 inches on the film.

4500 x 3000 pixels at 360 dpi correspond to 12.5 x 8.33 inches on the printing paper. The distance and the size of the printed pixels. It should have also indicated the inch dimensions.

This is a simple split …. 4500 pixels / 360 dpi = 12.5 inches.

Exactly the same pixels, but on film or paper media simply scaled to different inch sizes. This is an extremely important basic principle of printing. Dpi is just a number that exists only when the inches are specified.

At 4500 x 3000 pixels, the print size depends on the …
For example, if dramatically at 100 dpi, it would be 45×30 inches.
If printed at 300 dpi, then 15 x 10 inches.
If the printout is even scaled to 12 x 8 inches, 375 dpi will be output.

## Linear Algebra – Does the negative of the antihermitic matrix A become Hermitian or does it remain antihermitic?

Tried solution:
Let's say we have Matrix A, that is antihermitic.
$$A = – A ^ { dagger}$$
Take negative:
$$– A = – (-A) ^ { Dagger}$$
$$– A = A ^ { Dagger}$$
this shows that it is still anti-Hermitic. Multiplication of a negative thus has no influence on the fact that the matrix A is anti-Hermitic. Check my reasoning?

## Is it better to rotate or scan a movie negative for Lightroom?

I get reasonably good results when photographing negatives with a diacopter attachment and a macro lens (compared to using a flatbed scanner). However, if you want to scan many film images, consider using a special film scanner with a staple feeder. Depending on the lens and camera, the image quality of a film scanner may be better or not better, but it is much more practical.

Flatbed (or film) scanner

• Scanning negatives is an anticipated use case. Software usually has the ability to invert and color correct negatives, often with one click.
• The scanner may have automatic dust removal features (via an additional infrared channel).
• No demosaicing.
• If the picture does not look good, it is most likely a problem with the movie. (You do not have to constantly guess scanners and settings.)
• The light source is built into the scanner. The results are consistent.

• The capture process can be slow. Scanning is done line by line.
• Focus and resolution of some scanners may not be optimal.
• The scanner takes up space on the desk.
• The scanner probably can not extract all the information from the movie (grain structure and dynamic range).
• Software normally cuts frames automatically. You may experience problems when taking pictures with sprocket holes. (More problems with film scanners than with flatbeds.)

Other:

• Convenient if you are using an automatic feed film scanner.
• Flatbed with transparent adapter is the best (and cheapest) option for medium format.

Digital camera with diacopter

• Recording is fast (much like taking a picture).
• Can focus on the image grain with a good macro lens.
• Can extract more information from the image with increased magnification ratio (grain and dynamic range).
• No scanner that takes up space on the desk.
• Fairly affordable if you already own the camera and lens. (Dia-copier attachments cost between \$ 35 and \$ 50.)
• Depending on the attachment, images can be taken that project into the sprocket holes.

• More time is spent on post-processing images.
• Must demosaicize. Reduces the resolution and can cause artifacts.
• No automatic dedusting.
• Photographing negatives is Not a normal application.
• The camera may not measure properly.
• The white balance does not work properly.
• The software is not designed to invert and color correct negatives. You may need to spend a lot of time tweaking curves.
• If the picture does not look good, is there a problem with the movie, camera, or software? (Need to constantly consider if the camera or software is faulty.)
• Focusing on the grain can be difficult (depending on lens, magnification and eyesight).

Other:

• You need to buy a slide-copier attachment.
• You may need to buy a suitable lens.
• Aberrations and distortions depend on the lens.
• Contrast, sharpness and dynamic range depend on the lens.

• For best results, use a ratio of more than 1: 1 and one stitch.

• Depending on how careful you are, the lighting throughout the frame may not be even.

• Medium format …

• Difficult to find suitable Diacopier.
• When using a light box, alignment issues are likely to occur.
• You probably have to combine several pictures.

## Algorithms – Bellman Ford – negative cycle

This is my code for detecting a negative cycle in a graph using the Bellman-Ford algorithm, but I can not figure out why it returns an incorrect answer

``````public static final int INF = Integer.MAX_VALUE;
private static int negativeCycle(ArrayList() adj, ArrayList() cost) {
for(int i=0; i dep(j) + cost(j).get(v_index)) {
dep(v) = dep(j) + cost(j).get(v_index);

}
}
}
}

for (int j = 0; j < adj.length; j++) {
for (int v : adj(j)) {
if (dep(v) > dep(j) + cost(j).get(v_index)) {
return 1;
}
}
}

return 0;
}

## Plugin Development – Woocommerce removes negative charge after Ajax update

I'm trying to implement a system that automatically charges fees based on product attributes. The code initially adds the fee correctly, but after the order review area loader spins slightly, the fee is removed. I have been looking around the internet for some time and have not found a solution.

These are the requirements that occur at the same time as loading the order review:

/? wc-ajax = update_order_review <- this is probably the problem

And that's the code snippet in question:

``````\$ product = wc_get_product (\$ product_id);
\$ attributes = \$ product-> get_attributes ();
foreach (\$ attributes as \$ key => \$ attribute) {
if (\$ ending === \$ attribute-> get_options ()[0]) {
\$ cart-> add_fee (& # 39; discount for students at & # 39;. \$ attribute-> get_name (), \$ attribute-> get_options ()[1]- \$ product-> get_price ());
break;
}
}
``````
