数码相机拍摄出来的照片的格式是:
1、JPG格式,这种比较常见压缩格式,拍出来以后很容使用计算机查看,支持这种格式的软件很普遍,缺点是画质损失大,压缩越多损失越大。
2、传感器格式,不同品牌的相机生成的文件不尽相同,优点是画质没有损失,缺点是文件大,通用性不好,需要特定软件才能打开。
3、还有些格式,用得不普遍(PNG,)。
4、改变格式方法可以用右键点文件,点编辑,点文件---另存为选择一种其他的格式。
一般数码相机拍出来的视频通常是mts、mp4格式。其实格式只是一个封装,画质或后期制作的重要在于压缩编码。数码相机三大存储格式就是RAW、TIFF和JPEG。目前数码相机拍视频基本采用“AVC/H2.64”的编码方式。这种编码方式压缩效率高,画质好,是主流的编码方式。而一种压缩编码可以有多种封装格式,mts、mp4都是AVC/H2.64压缩编码。
大部分都是MP4格式的。
高清摄像机,即是可以高质量、高清晰影像,拍摄出来的画面可以达到720线逐行扫描方式、分辨率1280*720,或到达1080线隔行扫描方式、分辨率 1920 *1080的数码摄像机。
摄像机的清晰度取决于Sensor性能,CCD与CMOS两种感光芯片相比,CCD传感器在灵敏度、分辨率、噪声控制、高质量图像输出、动态影像表现方面都要优于COMS,所以绝大部分专业摄像机仍是选择CCD作为感光芯片,且高清百万像素网络摄像机选用的Sony 最高级ICX系列感光芯片具超低灵敏度照度,在黑暗的环境下取得更清晰的图像,是普通摄像机无法实现的。
偏灰是正常现象,别担心相机。
至于怎么解决,ps软件方法有几种
1、调整色阶,视情况调整,色阶可以增强明暗对比。
2、拉对比度,可以曲线,可以对比度。这一步什么时候用不好说,具体要在你弄好了清晰的色彩范围之后才行
3、可选颜色,一般将需要的颜色进行调整,比如下面的图片,天空颜色不好看,就选择黄色,增加红色。
4、两个图层,调整混合模式 这个你得自己试了,不同的混合模式效果不一样,柔光会增加亮度增显清新,正片叠底又会增加暗度提升质感,其它的不说了,附两张发灰的照片
第一步,将数码相机中的视频拷贝到电脑中;
第二步,在电脑中用格式工厂等软件将数码相机拷过来的视频转化成手机兼容格式视频文件;
第三步,将转换后的视频文件传输到手机上(是线传还是无线传看具备的条件而定。
如果是每张照片都过曝,应该是曝光补偿的设置问题,曝光补偿设置到+,就会曝光过度。你把曝光补偿设置为0,就恢复正常了。
如果只是有时会过曝,那就有可能是测光的模式设成“点测光”了,设置为区域测光或平均测光,一般都不会过曝了。
1、选中照片点右键属性,然后选摘要,一般会有照片数据信息,但也有时候不是很全。
2、用photoshop打开,选中照片,按快捷键 ctrl alt shift I ,就出来了。 用ACDSee打开图片,在选中图片上右键点属性。
3、网页上的图片,用一个小软件 ExifShow 抓取就可以了,网上搜索一下就有下载。希望能对你有所帮助!打开属性首先建议你选用RAW格式来拍照,这样在Photoshop打开时会直接显示属性。而且再后期调整上也十分的方便可信。如果是JPG的话可以直接打开属性,点击摘要,再点高级就会出现相片的一些基本属性。
性能好的数码相机如采用RAW格式拍照时,是尽量记录现场的全部信息,记录信息大的照片,会显得更灰,但后期的余量更大更灵活。
拍摄后文件的大小,跟相机的像素和你当时设置的文件质量和品质有关系,比如相机是1200w像素的机器,但你设成了640*480的邮件格式那样的话,拍出的照片大小可能就只有几百K甚至是几十K。
当然就算是相同的设置下,在不同的环境拍摄出的文件大小有不一样,拍摄纯黑色的对象和拍摄颜色丰富的对象,获得的照片大小会有比较大的差异。一种情况是相机的照片设置值过低,;
另一种情况,可能是你使用的是“缩略图”。还有就当然是像素小啊,130像素的摄像头最大分辨率是1280*960的图片在300多kb左右。图像 高 乘以 宽 就是像素大小,比如480*640的图片 就是480乘以640等于30万的像素,你的估计不到30万,所以图片小,导致的占用空间也小。
如果不是很老的手机或摄像头,你找找有没有设置,一般都会有设置的。20kb的图片估计是320*240或176*220的图片非常小的,在电脑上看你的照片 就像你的手机屏幕一样大,并且放大后非常浑浊。
Digital camera films the format of the photograph that come out is:
1, JPG format, this kind commonner compress a format, after be being patted very the look uses the computer to examine, the software that supports this kind of form is very general, defect is a picture qualitative loss is big, reduce more loss bigger.
2, sensor format, the file that the camera of different brand makes is endless and identical, the advantage is the picture does not have a loss character, defect is a file big, versatility is bad, need specific software ability to open.
3, return some forms, use unpopularly (PNG, ) .
4, change format method can order a document with right key, the dot edits, dot file---Put additionally to choose a kind of other forms.
The video that average number camera sends is format of Mts, Mp4 normally. Actually the format just is enclosed, what the picture pledges or later period makes is important depend on compressing encode. Digital camera format of 3 old memory is RAW, TIFF and JPEG. At present digital camera pats video to be used basically " AVC/H2.64 " encode means. Means of this kind of encode reduces efficiency tall, the picture has pledged, it is the encode means of the mainstream. And one kind compresses encode to be able to have a variety of enclosing format, mts, Mp4 is AVC/H2.64 compresses encode.
Be MP4 format for the most part.
High-definition camera, it is OK namely high quality, high-definition clear is video, film the picture that come out can obtain 720 lines 1280*720 of progressive scanning means, resolution, or reach 1080 lines the digital camera of 1920 *1080 of interlaced scanning means, resolution.
The definition of camera depends on Sensor function, photograph of two kinds of sensitive chip compares CCD and CMOS, CCD sensor is in side of dynamic and output of image of control of sensitivity, resolution, noise, high quality, video performance wants excel COMS, so majority major camera still is to choose CCD to serve as sensitive chip, and high-definition chip provides the sensitization of series of Sony ritzy ICX that camera of 1 million networks resembling element chooses exceed low sensitivity intensity of illumination, clearer picture is obtained below dark environment, common camera cannot come true.
Slant ash is normal phenomenon, do not worry about camera.
As to how to solve, ps software method has a few kinds
1, adjust color rank, inspect a circumstance to adjust, color rank can enhance contrast of light and shade.
2, draw contrast, can curve, can contrast. When is this one pace used bad to say, specific should be in your do well just go after distinct colour range
3, optional color, have the color of need adjustment commonly, leave the picture of the face for instance, celestial color is not good-looking, choose yellow, increase red.
4, two graphs layer, adjust mixture pattern this you yourself must try, distinct mixture mode effect is different, lambency can increase brightness to add show pure and fresh, positive folds a bottom to be able to increase again dark degree of promotion simple sense, of other did not say, add two pieces of pictures that send ash
The first pace, copy digital magazine video the; in computer
The 2nd pace, the video that waits for software to come over digital camera beat with format factory in computer is changed into the mobile phone; of file of compatible format video
The 3rd pace, transmit the video document after changeover the mobile phone to go up (it is a line passing still is wireless pass treat had condition and decide.
If be every pieces of photograph,expose to the sun too, should be problem of exposure compensatory setting, exposure compensation is installed + , meet overexposure. You are exposure compensation setting 0, returned to normal.
If just can expose to the sun too sometimes, that is to measure smooth mode to be set into likely " the dot measures light " , the setting measures light for area or measure light on average, won't expose to the sun too commonly.
1, pitch on photograph chooses right key property, choose a summary next, general meeting has photograph data news, but also not be very complete occasionally.
2, open with Photoshop, pitch on photograph, press shortcut key Ctrl Alt Shift I, came out. Open a picture with ACDSee, right on pitch on picture key chooses property.
3, the picture on the webpage, it is OK to use capture of ExifShow of a little software, search on the net have download. Hope to be able to be helped somewhat to you! Open attribute to suggest you choose RAW format to take a picture above all, show attribute directly in the meeting when Photoshop is opened so. And again later period is adjusted on also very convenient and authentic. If be of JPG,the word can open property directly, click a summary, nod again advanced a few major attribute with respect to meeting occurrence photo.
If the digital watch for a chance with good performance uses RAW when the format takes a picture, it is the complete information that records the scene as far as possible, record the picture with big news, can appear greyer, but the surplus of later period is larger more agile.
The size of the file after filming, the installs at that time like element and you document quality that follows camera and character are relative, for instance camera is the machine that 1200w resembles element, but the mail pattern that you set into 640*480 in that way word, the photograph volume that takes may have hundreds of K only is a few K even.
It is same setting to fall of course, film in different environment the file size that give has different, film the object of pure black and the object that film color is abounded, acquisition photograph bulk can have bigger difference.The photograph setting cost that a kind of circumstance is camera is too low, ;
Another kind of circumstance, the likelihood is you those who use is " skeletonize pursues " . Still having is small like element of course, 130 resemble element the picture that photographing the biggest like the head resolution is 1280*960 is controlled in 300 much Kb. Graph image height is multiplied with wide resemble element size namely, for instance the picture of 480*640 is 480 by with 640 be equal to of 300 thousand like element, your estimation is less than 300 thousand, the picture is so little, those who bring about take up the space is little also.
If not be very old mobile phone or photograph like the head, you search search to be installed, general metropolis has a setting. The picture of 20kb reckons the picture that is 320*240 or 176*220 is very little, the mobile phone screen that resembles you in the picture that you see on computer is euqally big, and enlarge hind is very cloudy.
