Photo processing workflow (zoom + GPS information + watermark + IPTC + EXIF, recommended software)

Today, I will explain the photo processing workflow, which is the whole process from taking a photo to releasing it to picasaweb. This process may only be a personal process, but I will share it with you.

Taking photos has become a habit. I basically put all the photos taken with my camera online. At this stage, more than 6000 photos are available. Thank you very much for Google Picasa Web features, so that I can store and perform secondary development (I will talk about it later). What should I do when the photos are taken out of the SD card and uploaded to Picasa Web? According to my needs, the content I want to handle includes:

1. Batch Scaling: scale down a 3072x2304 pixel photo because it is too large. If you upload a photo directly, it will waste a lot of space and the display speed will be low, so I want to scale it to 640x480 in batches, the capacity is much smaller, and the display speed is fast enough, so the pixels can be viewed on the Internet.

2. Add GPS information: Because I recorded tracks all the way and took photos, in order to finally pin my photos to Google Earth or Google Map, I want to add the GPS information to the photos, in fact, it is a GPS attribute information in EXIF, which also requires batch processing. The basic principle here is to first keep the camera time exactly the same as the GPS time, so that the photograph can correspond to the point or track segment in the track according to the camera time.

3. Add a watermark: Although not adding a watermark, the watermark is basically used to allow more people to access the image or protect the so-called copyright, at least use a watermark to describe that this photo is yours. I think most people want it.

4. You can view the title information of a photo on Picasa Web. You can view all the photos and describe the photos, such as the front entrance of a park, at first glance, people clearly understand the meaning of the photo. Many people use the method of naming a photo as a Chinese name, that is, using a file name to describe the content of the photo. In fact, this is unscientific because the Chinese name is unfriendly to URLs on the Internet, sometimes, when you upload a photo, the file will be automatically renamed, resulting in invalid Name Description. This is indeed a very urgent issue. Here, I take Picasa Web as an example. In fact, the description of photos on Picasa Web is in IPTC.

5. Add information in batch in EXIF: Because EXIF can have a lot of information to add, such as copyright, name, author, camera model, and even exposure, ISO, etc. For me, basically, you need to add names, copyrights, authors, and other information in batches. After uploading, you can learn more about the information, although this information cannot be directly seen.

Okay. For the above points, our workflow is also based on this. However, you can adjust the workflow according to your own needs. For example, the first and second steps do not need to be processed at all. Based on this workflow, I use the following software:

Google picasa3: A super simple and easy-to-use photo browsing processing software from Google, which is strongly recommended.

Gpicsync: powerful software that adds GPS information to photos. It is also open-source software and can export kml/kmz formats.

Photowatermark: batch photo watermark software, easy to use.

Cpicture: powerful photo processing software, but I basically only use it to process EXIF information in batches.

For other software, ACDSee is a simple software that allows you to view EXIF and IPTC information. irfanview is an open-source image-watching software similar to ACDSee, but I am not very familiar with it, most of them use the batch processing and Conversion Function to process photos in batches. photoinfo: Microsoft's tool is basically used to modify IPTC in batches. These three are basically the most auxiliary items.

We still use software to process photos Based on the workflow below:

Batch Scaling: import the photos to Google Picasa and use the export as HTML page function. Select a pixel, path, and template to export all your photos to a directory, images is the directory where all the scaled photos are located. You can also view the final Scaling Effect in IE. By the way, the HTML page export function also supports templates. You can customize a template that meets your needs. The template file is under the WEB \ templates directory. You need to know that when I was lazy, I made the template file, and then output HTML through Picasa, and then directly uploaded these files to the server, you can browse it, of course, this is an extremely lazy practice. Now, let's recommend a template Website: www. paulvanroekel. NL/Picasa, although there are not many templates, it is still good in general. For more information, see learning. I prefer the lightbox template.

For details about how to add GPS information, refer to my advanced tutorial on photo navigation. This article is a little better.

You can use the photowatermark software to add watermarks. It is very good, but you must first make a watermark. I have made two watermarks in the middle and bottom right corner. This software is also easy to use, I will not go into detail here.

For title display, import the added watermark to Picasa, browse the image, and enter the description directly, under the photo, "Create Image Description" is replaced with your own content. Picasa actually modifies the IPTC caption attribute. Because the IPTC information cannot be retained by the watermarking software, this step is carried out. Otherwise, I must first process IPTC information.

In EXIF, You need to modify the name, description, copyright, and other information. After finding all the images, click the EXIF information modification function in the lower left corner to pop out a box, fill in the name, copyright, description, and other information, and save the information in batch. Note that the caption attribute of IPTC content should not be changed to your own. Otherwise, if you leave it blank, it indicates that the content is unchanged.

The last step is to upload images. Of course, you can use the Picasa function to upload images to the online album. Simple. Here, I strongly recommend picasaweb. If you are still looking for online album albums, you should not find them. Google provides 1 GB of free space and supports external areas and speed, what do you have to worry about when you can use picasaweb for such convenient upload? Register one. 163 album, Baba change, Windows Live album, and so on are incomparable with picasaweb.

Let's talk about this. We recommend a few software. If you have any questions or better software recommendations, please mail me.
