QQ image and Picasa transverse evaluation

Mention Picasa many netizens are not unfamiliar, as Google's a free version of the image management software, it is probably already more famous than the ACDSee. Perhaps it is the old saying "tall tree catches", earlier this year, a feature from the appearance to the Picasa Tencent Image management software officially listed, after several months of improvement, yesterday, the name "QQ image" of the small software issued a new version. So this new QQ image can become Picasa's arch rival? Kothe, come on.

First, start speed

Start speed I am afraid that all picture software manufacturers are most afraid to neglect a problem, that is because of this reason, once mighty ACDSee finally fell a miserable ending. With this precedent, manufacturers will naturally be careful when designing. From the author's measured results (a total of three Tests, take three averages into the table), Picasa program to start when the average 1.16 seconds, and QQ image is 1.09 seconds, basically in the same grade. At the same time, because two software has provided the Picture Association service, may act as the default picture management program to appear, therefore the author then measured by the picture correlation starts the achievement, its result is 1.72 seconds (Picasa) and 1.06 seconds (QQ image), also is the QQ image slightly fast.

Second, display management

Picasa and QQ images are both intuitive thumbnail display mode, and can use the slider to adjust the size of the thumbnail in real time. However, the author thinks that the Picasa display management is more humane, for example, in its "view" → "thumbnail picture description" Under the label, provides a "resolution", "Picture name" and other common information display, after the check can directly identify these data to the bottom of the picture, for many day-to-day applications is very convenient. At the same time its sidebar slider is also joined the "magnetic" design, if the view is longer, as long as you hold down the slider icon, Picasa will be based on a certain speed and direction of automatic scrolling, much like IBM in the famous "Little Red Hat" pointing rod.

In addition, Picasa in the folder management is also quite distinctive, in addition to the same as the QQ image of the tree structure, but also provides a "tile" type display, can be taken time to be included in the picture folder of the peer list, it is appropriate to read a large number of photos. At the same time to facilitate the user to view, Picasa also specially added a "seamless browsing" design, you can pass through the sidebar slider to browse through all the photos, no matter which folder the photos belong to which disk, if coupled with the previous mentioned "magnetic slider", you will feel that the picture is actually a kind of enjoyment, This is what the QQ image is missing.

EXIF is a digital camera automatically recorded in the photos of the shooting data, can help users to restore the scene of the shooting. Although the two software has all provided EXIF query, in contrast, I prefer the Picasa kind of direct display design. And as a result of QQ image using a group-style display, to see the parameters of the mouse instead of a little more, the total feeling there is so little superfluous.

In fact, the two software in the humanization of a small difference, that is Picasa allows the view of the picture directly dragged to the system desktop or other folders, to achieve rapid replication of the picture, and QQ image does not have this function.

Three, full screen preview

Since the two software supports picture-related services, double clicking the picture will go into a full-screen preview mode. By default, Picasa and QQ images will automatically shrink the image to ensure that the user sees a complete picture. And the surrounding space will be filled with translucent, the overall effect is very cool! However, compared to, the author prefers QQ image design, which "left", "right", "edit", "proportion" and other commonly used buttons are arranged in the bottom of the screen, not only convenient but eye-catching. At the same time its shortcut keys are more in line with the domestic user's habits, such as "space"/"Left and right cursor" can be quickly read and backward photos, "up and down cursor" can quickly modify the display ratio.

The highlight of Picasa is its unique "Picture selection bar", which allows you to quickly preview other photos with your mouse. Unfortunately, the actual use of this sidebar is always overlapping with the common toolbar, seriously affecting the use of toolbars. And more people scratching their heads is the shortcut key design is very uncomfortable (such as using "J", "K" to represent the "previous", "Next"), easy to use? At least I feel inferior to QQ image good remember.

Four, picture editor

"Simple edit" has now become the standard for picture software, and the more powerful the function, the more simple the operation. The bright spot of QQ image is the "one key beautification" under the label of "Fast tune", and all kinds of beautiful and interesting image border and adornment. In a sense, walking is in fact the beauty of Mito, can be cow image of the popular style. And Picasa is more focused on professional corrections, in addition to more extensive visual effects, but also increased the picture histogram display. But the border and adornment did not appear in Picasa body, probably is the software localization reason.

In addition, I think the QQ image of "Two-picture contrast" and "History list" is also a good design, the former can be the original and the final effect of 1:1 contrast, and the latter can be quickly implemented to restore, which in the actual combat but quite practical!

"Two-picture contrast" and "historical list" of QQ images

It is worth mentioning that Picasa can support the batch processing of many groups of pictures, and the QQ image does not have this function, but the actual work of the bulk operation of the use is much more ah!

Five, upload the network album

Compared with traditional photo management software, the QQ image and Picasa are fused into the most popular network synchronization modules. Of course, for selfish reasons, both sides are using their own online albums. Among them Picasa hangs is own "gu ge Picasa album", and the QQ image nature is the famous "QQ album".

Figure 13 Multi-image upload

From the measured results, the QQ image and Picasa have provided multiple graphics one key upload service, and the speed is also good! The difference is that Picasa provides more upload options (such as uploading and automatically modify picture size, directly modify album permissions, etc.), while the QQ image is only a simple album selection, The only consolation is that both support "no compression upload."

Vi. Photo Introduction and search

Compared with the mature management software such as Picasa, the QQ image has a fatal problem, that is, does not support directly from the digital camera to import photos, obviously this is a difficult to accept the fact. and Picasa in addition to providing from DC, scanners, U disk and other media to import photos of the function, but also in the import box set up a photo selection and preview area. Can be based on the actual situation to decide to import the photos, very flexible.

In addition, although both provide a fast search function, but from the measured comparison, Picasa's search ability is far stronger than the QQ image. Because in addition to the most basic cross folder search, search real-time hints, its biggest feature is to support EXIF search. For example, when we want to look up all the photos taken by the Nikon camera in the computer, just type "Nikon" into the search box.

Vii. Other Highlights

If the QQ image has been out of the way, then Picasa still has a lot to boast of the bright spot. such as "facial recognition" that can automatically identify faces, directly on the map marked "geographical mark", a key to upload the author blog "Blogthis", there are "rapid production of picture collage", "Multiple graphics production slide Video", "one key to achieve network printing" and other small functions. Of course, due to the difference in positioning, some features may not adapt to the domestic user habits, but better than nothing, there is always stronger than no!

Written in the last

Obviously a contrast, QQ image at most just and Picasa made a shape (also seems to be a bit worse), especially in detail is still very far, there is no other Tencent software that is born with the "high starting point." And today's test also from a side of the performance, do not simply imitate the software can be successful, only from the user's most basic use point of view, can really make a good tool. And from this point of view, QQ image I am afraid the road is still very long!
